[osg-users] OpenSceneGraph-3.3.3 developer release
Robert Osfield
I have just tagged the 3.3.3 developer release. A quick copy and paste of what I've just written up on the website:
OpenSceneGraph-3.3.3, released on 19th December 2014, key deliverables in this dev release are:
- New
osgTerrain::DisplacementMappingTechnique that uses sharing of geometry
tiles and height field textures to render the terrain, reducing main
memory and GPU memory usage to less than 40% of previous usage, and
reduces GPU costs to around 60% of previous requirements for a terrain.
- New LAS plugin (depends upon libLAS and Boost)
- New GStreamer plugin for cross platform video
- New OpenGL extension set-up architecture that reduces both the code footprint, library size and runtime memory footprint, as well as make it easier to extend.
- Support for glVertexAttribDivisor via new osg::VertexAttribDivisor StateAttribute
- Support for glBlendEquationi, glBendFunci, glColorMaski and glEnable/glDisablei iva new BlendEquationi, BlendFunci, ColorMaski, and Enablei/Disablei StateAttributes to better support Multiple Render Target usage.
- New osg::ShaderStorageBufferObject class and osgssbo example.
- New osggpucull example that demonstrates culling on the GPU.
- Threading safety and performance improvements to the DatabasePager
- Refactor of osg::Drawable so that it is no subclassed from osg::Node allow it to be directly placed in the scene graph without the need for a Geode parent.
- Standardization of callbacks in Node, Drawable, StateSet and StateAttributes
- Improved Android toolchain build
- Improvements to QT4 and QT5 support in osgQt
- Improvements to the new osgUI NodeKit and Lua Scripting support
- Bug and build fixes

variables set to NOT-Found being used in searching
2014-12-19 08:25 robert
* CMakeModules/FindLIBLAS.cmake: Fixed script warnings
2014-12-18 17:47 robert
* CMakeLists.txt, CMakeModules/FindLIBLAS.cmake,
src/osgPlugins/CMakeLists.txt, src/osgPlugins/las,
src/osgPlugins/las/CMakeLists.txt,
src/osgPlugins/las/ReaderWriterLAS.cpp: From Aitor Moreno, LAS
plugin - depends upon boost and liblas and liblas-c
2014-12-18 16:52 robert
* PlatformSpecifics/Android/Application.mk.master.in: From Adrian
Clark, build fix for recent Android NDK using the old Android
build approach.
2014-12-18 15:59 robert
* CMakeLists.txt: From Mattias Helsing, "CMake have release 3.0 and
3.1 and we have some bad checks for cmake
major version when settings cmake policies in CMakeLists.txt.
This fixes it"
2014-12-18 11:36 robert
* AUTHORS.txt, applications/osgversion/Contributors.cpp: Updated
AUTHORS
2014-12-18 11:19 robert
* ChangeLog: Updated ChangeLog in prep for dev release
2014-12-18 11:09 robert
* examples/osgmovie/CMakeLists.txt: Fixed warning
2014-12-18 10:59 robert
* include/osg/DisplaySettings, src/osg/DisplaySettings.cpp: Added
DisplaySettings::s/getNvOptimusEnablement() and
OSG_NvOptimusEnablement env var control to control the setting of
the NvOptimusEnablement variable
2014-12-18 09:24 robert
* src/osgPlugins/fbx/ReaderWriterFBX.cpp: From Sukender, "Added
options to the FBX writer: an ascii/binary switch, and the
ability to select FBX version as the SDK handles it (Ex:
"FBX201300").
This allows the user to achieve backward compatibility, and debug
format issues using text output."
2014-12-18 09:03 robert
* CMakeModules/FindGStreamer.cmake: From Mattias Helsing, "The
addition of the GStreamer cmake find script broke my build
because
cmake vars weren't passed correctly to find_package_handler_args,
so
while the find script didn't find a single required GStreamer lib
or
include path it still reported GSTREAMER_FOUND=TRUE (and then
tried to
compile the new plugin). This fixes it and correctly reports
missing
components."
2014-12-17 19:21 robert
* CMakeLists.txt, CMakeModules/FindSDL2.cmake,
examples/osgmovie/CMakeLists.txt, examples/osgmovie/osgmovie.cpp:
Added support for using SDL2 to the osgmovie to enable it to
handle floating point audio formats
2014-12-17 19:20 robert
* CMakeModules/FindFFmpeg.cmake,
src/osgPlugins/ffmpeg/FFmpegDecoderAudio.cpp: From Javier Taibo,
" I have found that since version 1.1, FFMPEG changed the way
audio streams are retrieved, from packed to planar format. SDL
interprets packed audio, as is used in the osgmovie example. To
make the audio work when the OSGffmpeg plug-in is compiled
against recent FFMPEG versions, FFmpegDecoderAudio must check for
planar formats and in these cases request the samples as packed.
This way all works as before. It can be checked with osgmovie
example application.
$ osgmovie --audio movie.avi.ffmpeg
FFmpegImageStream::open audio failed, audio stream will be
disabled: unknown audio format
With the attached FFmpegDecoderAudio.cpp, audio sounds correctly.
I am also attaching a modified version of FindFFmpeg.cmake that
allows to set as FFMPEG_DIR the ffmpeg compiled in the source
directory structure. It should not break anything as it only adds
some additional search paths.
"
Note from Robert Osfield, I have found in testing that audio
quality is not good for planar floating point formats, even with
adding support for SDL2 to the osgmovie example. I haven't yet
tracked down the cause of these audio problems or a solution.
2014-12-17 10:19 robert
* src/osgPlugins/fbx/ReaderWriterFBX.cpp: From Sukender, "FBX
writer was writing an empty file when the scene had a root node
being a Geode.
This was caused be the change in Drawable (now derived from Node)
and Geode (now derived from Group).
This fix simply sticks with previous behaviour. Another change
could be to adapt WriterNodeVisitor.
"
2014-12-16 17:37 robert
* src/osgPlugins/gstreamer/GStreamerImageStream.cpp: Fixed warnings
and memmory leaks

Added support for ImageStream::LoopigMode variable
Fixed memory leak associtied with restarting videos
Changed Image::setData() to Image::dirty() to avoid resetting
data
2014-12-16 11:20 robert
* CMakeLists.txt, CMakeModules/FindGLIB.cmake,
CMakeModules/FindGStreamer.cmake, src/osgPlugins/CMakeLists.txt,
src/osgPlugins/gstreamer,
src/osgPlugins/gstreamer/CMakeLists.txt,
src/osgPlugins/gstreamer/GStreamerImageStream.cpp,
src/osgPlugins/gstreamer/GStreamerImageStream.hpp,
src/osgPlugins/gstreamer/ReaderWriterGStreamer.cpp: From Julen
Garcia, "Here there is a small plugin I use to play video files.
It is based on GStreamer http://gstreamer.freedesktop.org and I
have used the FFmpeg plugin as inspiration."
From Robert Osfield, fixed handled of row widths so that they are
padded to a 4 byte boundary as certain row widths were being
rendered incorrectly.
2014-12-16 09:34 robert
* include/osg/TriangleLinePointIndexFunctor,
include/osgUtil/MeshOptimizers, src/osgUtil/MeshOptimizers.cpp:
From Marc Helbling, "please find enclosed a submission that
should improve the VertexAccessOrderVisitor (pre-transform)
optimizer:
* it sorts primitives to keep "more complex" primitives first;
maybe you'll prefer to have this as an option (but usually it
should make more sense to pre-transform triangles before e.g.
lines)
* currently, the visitor rely on TriangleIndexFunctor and does
not take care of points and lines (see
https://github.com/openscenegraph/osg/blob/master/include/osg/TriangleIndexFunctor#L124-130).
This can lead to issues e.g. if you store the wireframe lines
along with some triangles: the triangles will be reindexed but
not the line. I've therefore added
osg/include/TriangleLinePointIndexFunctor to index triangles,
lines and points and derived VertexReorder from this class.
* to avoid issues, shared arrays are duplicated. However, in some
cases (e.g. an UV channel shared in the geometry only) this is
not required. I'm adding a SharedArrayOptimizer to optimize this:
it looks for duplicated UVs before the array duplication and
deduplicate arrays after.
"
2014-12-15 17:15 robert
* include/osgUtil/TriStripVisitor, src/osgUtil/TriStripVisitor.cpp:
From Marc Helbling, "please find the mergeTriangleStrip code
merged in osgUtil::TriStripVisitor.
I've removed the references to DrawArrays as we should no longer
produce any.
Note that:
* as the name suggest, it only works for triangle strips but
could probably be easily extended to quads
* the resulting primitive is not highly optimized; we could
probably sort the strips in order to minimize the number of
primitive restart
* as we may merge DrawElementsUInt and DrawElementUShort, the
code will only generate DrawElementsUInt"

src/osg/CMakeLists.txt: From PawelKsiezopolski, "This submission
contains a new example for OSG : a geometry instancing rendering
algorithm consisting of two consequent phases :
- first phase is a GLSL shader performing object culling and LOD
picking ( a culling shader ).
Every culled object is represented as GL_POINT in the input
osg::Geometry.
The output of the culling shader is a set of object LODs that
need to be rendered.
The output is stored in texture buffer objects. No pixel is drawn
to the screen
because GL_RASTERIZER_DISCARD mode is used.
- second phase draws osg::Geometry containing merged LODs using
glDrawArraysIndirect()
function. Information about quantity of instances to render, its
positions and other
parameters is sourced from texture buffer objects filled in the
first phase.
The example uses various OpenGL 4.2 features such as texture
buffer objects,
atomic counters, image units and functions defined in
GL_ARB_shader_image_load_store
extension to achieve its goal and thus will not work on graphic
cards with older OpenGL
versions.
The example was tested on Linux and Windows with NVidia 570 and
580 cards.
The tests on AMD cards were not conducted ( due to lack of it ).
The tests were performed using OSG revision 14088.
The main advantages of this rendering method :
- instanced rendering capable of drawing thousands of different
objects with
almost no CPU intervention ( cull and draw times are close to 0
ms ).
- input objects may be sourced from any OSG graph ( for example -
information about
object points may be stored in a PagedLOD graph. This way we may
cover the whole
countries with trees, buildings and other objects ).
Furthermore if we create osgDB plugins that generate data on the
fly, we may
generate information for every grass blade for that country.
- every object may have its own parameters and thus may be
distinct from other objects
of the same type.
- relatively low memory footprint ( single object information is
stored in a few
vertex attributes ).
- no GPU->CPU roundtrip typical for such methods ( method uses
atomic counters
and glDrawArraysIndirect() function instead of OpenGL queries.
This way
information about quantity of rendered objects never goes back to
CPU.
The typical GPU->CPU roundtrip cost is about 2 ms ).
- this example also shows how to render dynamic objects ( objects
that may change
its position ) with moving parts ( like car wheels or airplane
propellers ) .
The obvious extension to that dynamic method would be the
animated crowd rendering.
- rendered objects may be easily replaced ( there is no need to
process the whole
OSG graphs, because these graphs store only positional
information ).
The main disadvantages of a method :
- the maximum quantity of objects to render must be known
beforehand
( because texture buffer objects holding data between phases have
constant size ).
- OSG statistics are flawed ( they don't know anymore how many
objects are drawn ).
- osgUtil::Intersection does not work
Example application may be used to make some performance tests,
so below you
will find some extended parameter description :
--skip-dynamic - skip rendering of dynamic objects if you only
want to
observe static object statistics
--skip-static - the same for static objects
--dynamic-area-size - size of the area for dynamic rendering.
Default = 1000 meters
( square 1000m x 1000m ). Along with density defines
how many dynamic objects is there in the example.
--static-area-size - the same for static objects. Default = 2000
meters
( square 2000m x 2000m ).
Example application defines some parameters (density, LOD ranges,
object's triangle count).
You may manipulate its values using below described modifiers:
--density-modifier - density modifier in percent. Default = 100%.
Density ( along with LOD ranges ) defines maximum
quantity of rendered objects. registerType() function
accepts maximum density ( in objects per square kilometer )
as its parameter.
--lod-modifier - defines the LOD ranges. Default = 100%.
--triangle-modifier - defines the number of triangles in finally
rendered objects.
Default = 100 %.
--instances-per-cell - for static rendering the application
builds OSG graph using
InstanceCell class ( this class is a modified version of Cell
class
from osgforest example - it builds simple quadtree from a list
of static instances ). This parameter defines maximum number
of instances in a single osg::Group in quadtree.
If, for example, you modify it to value=100, you will see
really big cull time in OSG statistics ( because resulting
tree generated by InstanceCell will be very deep ).
Default value = 4096 .
--export-objects - write object geometries and quadtree of
instances to osgt files
for later analysis.
--use-multi-draw - use glMultiDrawArraysIndirect() instead of
glDrawArraysIndirect() in a
draw shader. Thanks to this we may render all ( different )
objects
using only one draw call. Requires OpenGL version 4.3 and some
more
work from me, because now it does not work ( probably I
implemented
it wrong, or Windows NVidia driver has errors, because it hangs
the apllication at the moment ).
This application is inspired by Daniel Rákos work : "GPU based
dynamic geometry LOD" that
may be found under this address :
http://rastergrid.com/blog/2010/10/gpu-based-dynamic-geometry-lod/
There are however some differences :
- Daniel Rákos uses GL queries to count objects to render, while
this example
uses atomic counters ( no GPU->CPU roundtrip )
- this example does not use transform feedback buffers to store
intermediate data
( it uses texture buffer objects instead ).
- I use only the vertex shader to cull objects, whereas Daniel
Rákos uses vertex shader
and geometry shader ( because only geometry shader can send more
than one primitive
to transform feedback buffers ).
- objects in the example are drawn using glDrawArraysIndirect()
function,
instead of glDrawElementsInstanced().
Finally there are some things to consider/discuss :
- the whole algorithm exploits nice OpenGL feature that any GL
buffer
may be bound as any type of buffer ( in our example a buffer is
once bound
as a texture buffer object, and later is bound as
GL_DRAW_INDIRECT_BUFFER ).
osg::TextureBuffer class has one handy method to do that trick (
bindBufferAs() ),
and new primitive sets use osg::TextureBuffer as input.
For now I added new primitive sets to example (
DrawArraysIndirect and
MultiDrawArraysIndirect defined in
examples/osggpucull/DrawIndirectPrimitiveSet.h ),
but if Robert will accept its current implementations ( I mean -
primitive
sets that have osg::TextureBuffer in constructor ), I may add it
to
osg/include/PrimitiveSet header.
- I used BufferTemplate class writen and published by Aurelien in
submission forum
some time ago. For some reason this class never got into
osg/include, but is
really needed during creation of UBOs, TBOs, and possibly SSBOs
in the future.
I added std::vector specialization to that template class.
- I needed to create similar osg::Geometries with variable number
of vertices
( to create different LODs in my example ). For this reason I've
written
some code allowing me to create osg::Geometries from osg::Shape
descendants.
This code may be found in ShapeToGeometry.* files. Examples of
use are in
osggpucull.cpp . The question is : should this code stay in
example, or should
it be moved to osgUtil ?
- this remark is important for NVidia cards on Linux and Windows
: if
you have "Sync to VBlank" turned ON in nvidia-settings and you
want to see
real GPU times in OSG statistics window, you must set the power
management
settings to "Prefer maximum performance", because when "Adaptive
mode" is used,
the graphic card's clock may be slowed down by the driver during
program execution
( On Linux when OpenGL application starts in adaptive mode, clock
should work
as fast as possible, but after one minute of program execution,
the clock slows down ).
This happens when GPU time in OSG statistics window is shorter
than 3 ms.

CMakeModules/FindQuickTime.cmake,
src/osgViewer/PixelBufferCocoa.mm: From Jan Klimke, "i noticed,
that there are a couple of additional flaws when building osg for
Mac OS X 10.10 Yosemite.
The mac os sdk version is recognized by the current CMAKE script
as 10.1 instead of 10.10 since it cuts the version string from
the 4th place. I introduced a more reliable version checking
based on splitting the returned version code into MAJOR MINOR and
PATCH parts and reassemble the OSG sdk version afterwards.
I replaced the existing CMake code against the following
(returning now version 10.10 as expected):
# Determine the canonical name of the selected Platform SDK
EXECUTE_PROCESS(COMMAND "/usr/bin/sw_vers" "-productVersion"
OUTPUT_VARIABLE OSG_OSX_SDK_NAME
OUTPUT_STRIP_TRAILING_WHITESPACE)
STRING(REPLACE "." ";" MACOS_VERSION_LIST ${OSG_OSX_SDK_NAME})
LIST(GET MACOS_VERSION_LIST 0 MACOS_VERSION_MAJOR)
LIST(GET MACOS_VERSION_LIST 1 MACOS_VERSION_MINOR)
LIST(GET MACOS_VERSION_LIST 2 MACOS_VERSION_PATCH)
SET(OSG_OSX_SDK_NAME
"macosx${MACOS_VERSION_MAJOR}.${MACOS_VERSION_MINOR}")
Also i added the check for the new Version to some more find
scripts.
Additionally the nil object in Objective C now seems to be
equivalent with a null_ptr that cannot be passed as GLInt
anymore. So i switched this in the PixelBufferCocoa.mm to pass a
zero instead of nil.

* src/osgDB/CMakeLists.txt, src/osgDB/FileUtils.cpp: From Alberto
Luaces,"the current code uses the preprocessor for generating the

a way that when CMAKE_INSTALL_PREFIX contains something along the

of
/usr/x86_64-linux-gnu/
it gets substituted as
/usr/x86_64-1-gnu/
that is, the string is preprocessed again, thereby making changes
to
anything that matches any defined symbol, as "linux" in this
example
(https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=763816).
Quoting that path directly in CMake scripts solves that problem.

src/osgWrappers/serializers/osg/LibraryWrapper.cpp: From Rafa
Gaitan, "I finally had some time to change the build system for
Android using a Toolchain, which, I think, will be easier to
maintain and uses cmake standard system to build it.
My changes:
-------------------
- I changed the cmake files and added a toolchain for building
OSG in Android. The toolchain is based on the one used at OpenCV.
For building OSG for android you just need to do:
mkdir build_android_static_gles2 && cd build_android_static_gles2
cmake .. -DANDROID_NDK=<path-to-the-android-ndk>
-DCMAKE_TOOLCHAIN_FILE=../PlatformSpecifics/Android/android.toolchain.cmake
-DOPENGL_PROFILE="GLES2"
-DDYNAMIC_OPENTHREADS=OFF
-DDYNAMIC_OPENSCENEGRAPH=OFF
-DANDROID_NATIVE_API_LEVEL=15 # optional
-DANDROID_ABI=armeabim #optional
-DCMAKE_INSTALL_PREFIX=<path-to-the-install-path> #optional
make -j 8
make install
The OPENGL_PROFILE works as expected, changing it to "GLES1" it
builds and links OSG using GLES1.
The DYNAMIC_OPENTHREADS/DYNAMIC_OPENSCENEGRAPH parameters also
allows to build the dynamic libraries
- I also added some build fixes for android related to the
texture formats and added some missing USE_OSG_SERIALIZER_WRAPPER
in the osg serializer library to support loading osgb files in
static."

with VBO's to try to get them on par with display

deeper I found out it came from State::disableTexCoordPointer
where
the function would call glClientActiveTexture but not
glDisableClientState because the geometry didn't have texture
coordinates for that channel. This is because in our scene there
are
some geometries that have move than one uv channels making
State::_texCoordArrayList grow. Then the method
State::applyDisablingOfVertexAttributes() will call
disableTexCoordPointer multiple times.
I rearrange the method a little to combat this. Now the logic has
the
same ordering as disableTexCoordPointersAboveAndIncluding which
already combats this."

* src/osgPlugins/txp/ReaderWriterTXP.cpp: From Ryan Kawicki, "There
is an issue where the model insets of a terrex terrain are being
removed during the loading process. The issue is described below.
- the issue here is that the plugin is removing group nodes if
that group node only has one child. becuase transforms are also
group nodes, there were cases when the transform would have only
one child under it and would cause it to remove the translation
portion. this would cause all the vertex data to be loaded around
the last matrix operation, which in our case was the origin
(0,0,0).
We work off of OSG 2.8.1 but see that this has not been addressed
on latest yet. I’ve tested this against 2.8.1 and have cleanly
applied it to my local repository off of latest."
2014-08-08 16:34 robert
* src/osgUtil/RenderStage.cpp: From Tim George, "Currently there is
a problem with using a camera with a viewport with a non 0 offset
and also using an FBO. The problem is that only area made up of
the viewports width and height is drawn based on an offset of 0,0
instead of using the viewports offset.
It is caused by line 991 in RenderStage.cpp:
Code:
fbo_ext->glBlitFramebuffer(
0, 0, static_cast<GLint>(_viewport->width()),
static_cast<GLint>(_viewport->height()),
0, 0, static_cast<GLint>(_viewport->width()),
static_cast<GLint>(_viewport->height()),
blitMask, GL_NEAREST);
which is not taking into account the viewport x and y when
performing the blit. It probably should be:
Code:
fbo_ext->glBlitFramebuffer(
static_cast<GLint>(_viewport->x()),
static_cast<GLint>(_viewport->y()),
static_cast<GLint>(_viewport->width()) +
static_cast<GLint>(_viewport->x()),
static_cast<GLint>(_viewport->height()) +
static_cast<GLint>(_viewport->y()),
static_cast<GLint>(_viewport->x()),
static_cast<GLint>(_viewport->y()),
static_cast<GLint>(_viewport->width()) +
static_cast<GLint>(_viewport->x()),
static_cast<GLint>(_viewport->height()) +
static_cast<GLint>(_viewport->y()),
blitMask, GL_NEAREST);
"
Note from Robert Osfield, made small tweak to above on merge,
changing the width+x to x+width to make it read more naturally.
2014-08-08 16:09 robert
* src/osgUtil/MeshOptimizers.cpp: From Marc Helbling, "please find
a fix for the vertex pretransform visitor
(VertexAccessOrderVisitor).
The issue with current code is that arrays are collected *before*
duplicating shared arrays which leads to arrays that are
correctly duplicated but that are not reordered.
Also the submitted patch contains a small cleaning in
GeometryArrayGathrer as the _useDrawElements variable is not
used; it is only set in the GeometryArrayGathrer constructor and
VertexAccessOrderVisitor already checks that primitives have
indexed type."

would you expect problems with old osgTerrain databases (build with ~3.2.0, osgb format)?
I have some strange behaviour with a huge database, which simply not displayed anymore and somehow breaks state (See attached picture).
Also there is a warning coming from an optimzer I guess:
Warning: CollectLowestTransformsVisitor::removeTransforms() error, encountered a NULL Transform pointer
A second, much smaller database is sometimes displayed, but crashes the viewer sometimes.
Unfortunately my first email, containing a database didn't get through.
It is really hard to find the culprit.
Any hints?
I'll investigate the issue further ...
Cheers
Sebastian

Hi All,
Sebastian Messerschmidt
I've identified one crash in the GLBufferObject::bindBuffer due to an uninitialized _extension member.
It seems, it gets destroyed somewhere in the middle. Unfortunately the GLExtensions object doesn't have a declared destructor, so chasing this down is harder than I thought.
I'll analyze futher.
Btw. I've already rebuild cleanly and used the HEAD for testing, but it seems the behaviour stays the same.
Cheers
Sebastian
Sebastian Messerschmidt
as already written, the problem is an invalidated _extensions object.
It seems to be invalidated by the State destructor, which causes the destructor of the GLExtensions object to be called. (I've got there using a memory breakpoint)
I've attached a callstack for analysis. (i've added a destructor for the GLExtensions for testing)
Cheers
Sebastian

I haven't had chance to try and reproduce the bug yet. The description sounds like there an initialization order issue with the osg::State. In theory the osg::State object now does the initalization, and the osg::GraphicsContext on the first makeCurrent() should ensure that it's set up correctly, in theory this should be the first set of OpenGL calls made.

What is application you are testing within? What is the platform?
It is crashing in a minimal application as well as using osgviewer.
Have you tried to use my minimal database? It reproduces the crash when loading it with the osgviewer and stiring around with the mouse a bit. (Also take a look at the attached picture: It shows a messed up State)
I was able to fix the crash by removing the GLExentsions::Set(contextId,0) in the State destructor. But this seems plain wrong. I suspect on my platform, the State is cleared and reinitialized for some reason.
When I can spent some time on this, I can try to create a minimal example. Just out of curiosity: Is there any reason for the State to remove the extensions for the ContextID? I suspect there is only one State per Context, which seems ok, but I cannot grasp, why it is released in my scenario.
Also I had problems after the fix loading other databases; It seems the range lists in paging are invalid. It randomly displays the wrong tiles with wrong facing. I'll try to hunt this down too.
Any suggestions how to narrow down the problem on my side?
Cheers

The design is meant to have the osg::State created by an osg::GraphicsContext and managed through the lifetime of that GraphicsContext. One shouldn't in theory be creating osg::State or destroying osg::State outside of this context usage.
Something somewhere is obviously trying to do it's own thing w.r.t osg::State, right now I don't know where this might be.

What do you mean by range lists? You'll need to send me a screen shot.
Doing cross testing, it works fine with a osg111 version (I don't have the osgversion with this deploy, so it is hard to tell you which version this is exactly).
Robert.

I will now focus on why the stats is causing a crash as it's something I can reliably recreate and get a stack trace from. Fixing this might address or reveal what other things are going amiss.
I have have add a check into the osg::State destructor to avoid calling GLExtensions::Set() if the local State::_glExtensions pointer is NULL. This fixes the crash and is now checked into svn/trunk. I'm still get bad font for the stats though, and the tiles still appear inappropriately in your dataset. Will keep investigating.
Robert.
Sebastian Messerschmidt
If I can provide any details/additional test results, let me know.
Robert Osfield
I have now been able to reproduce the odd behaviour with the svn/trunk version of the OSG and your data.
OSG-3.2.2 mostly works fine, I only have to rotate the viewer camera around to see the tiles appear and then the LOD's all work fine, it does however cause problems with the font of the stats when I bring them up. I do however the the "Warning: CollectLowestTransformsVisitor::removeTransforms() error, encountered a NULL Transform pointer" with OSG-3.2.2 as well.
Robert Osfield
Could you try svn/trunk to see if the fix I checked in today address this crash?
Thanks,
Robert.
Hi,
If it's of any help I've observed pretty much the same thing, when using the old geometrytechnique (win 7 VS2010). I've tried with .osgb and .ive vpb generated terrain databases.
With a singlethreaded viewer it seems to work although crashes when opening the stats.
With a multithreaded viewer though I consistently get a crash in osg::State during the first frame.
Cheers

Attached is a link[1] to the database build with the current trunk of OSG and VPB.
It works as intended with the trunk osgviewer.
However, I think I just found the next issue :-(
I cannot use vpbmaster anymore for compiling. It gets stuck after adding all tasks (I've waited a fair amout of time) . I didn't find an indication why the tasks are not starting (no osgdem process is started).
So the presented database is structured differently, as it was build using osgdem soley.

Hi Robert,
Did you have a chance to look into this?
Currently wrapping my head around controlling shaders in a more compatible way to old fixed function pipeline.
Sebastian Messerschmidt
If you are doing any work on the ShaderComposition, please spent 5 minutes on this, as this is a relatively small change to enable user defined composition schemes:
<snip>
Great. I've been doing something like this by modifying the ShaderComposition (as proposed by you) and injection defines at start of the composed shader.
It still seems to be a clutch, so I'm looking forward to your ideas. If you want to, I'm totally happy to share my insights.
I had some request to review it some months ago, but you where into some other stuff at this time, so it might have ended up below the radar. (The topic was "[osg-users] ShaderComposer and some missing features")
</snip>
In my derived ShaderComposer I ended up in having a bunch of defines and an include system composing the shaders. The defines are like "techniques" where you enable bumpmapping/HDR or whatever you like. The shader composition will then create the combinations as needed and inject the code and includes. (which usually hold utility functions or define the technique-specific functionality).

Recompiling would be my total last Option, as it would take a week or more.
Basically I need a clear way to recreate problems.
https://drive.google.com/file/d/0Bz3BDTPpY5sxekZhd1ZMU2VSYkU/edit
Also the first database sent (opening this thread) will be totally messed. (culling goes crazy and sometimes stats display will be garbage).
I know it would be totally better to recompile the databases, but I cannot do this with any minor release unfortunately, since it it simply takes a lot of resources.

Well I've done what I can, various bugs have been fixed along the way. The database you've provided is working as far as I can tell.
It's really now up to you to test at your end. Recompiling the OSG should not take "a lot of resources". I recompiled the fresh builds of the OSG under Windows and Linux this morning is prep for OSG-3.3.4, it didn't take me a week.
They worked for quite a while and got broken with the new 3.3.3/4 trunks.
Sorry, if there is some misunderstanding of some kind. I tryed to debug what is going on but I'm simply clueless and I somehow would expect the attached database to still work.
Robert Osfield
'm not talking recompiling OSG. I'm referring to the re-attached database from the start of this thread, which is a downscaled version of my huge database, and shows problems with culling and somehow cripples the stats-viewer.

I quite literally can't keep afford to chasing this stuff up with so little to go on.
Any idea what might got broken on the way? With all due respect, and I have a lot for your work, I don't think that unintentional incompatibilities regarding the format can be tolerated.
In retrospective you encouraged me and others to try the trunk, and there we are ... I found a couple of bugs and tried to give as much detail and context as possible here - and also I offered to do whatever needed t chase down the bug.
I do understand, that you cannot spend your time on chasing arbitrary bugs, with no samples, context etc. provided, but please try to see it from my point of view: Things got broken, and I don't know how to fix them.
Robert Osfield
It worked with older osg-versions, so database generation can be rules out. It stopped working with the 3.3.3 developer release.
It is visible only from the back-side, so stirring around with the mouse will display it. The information is in the thread, so I can only try to resummarize, what is going on.
