Strange Octane texturing problem
Torgeir Lilleskog
I have an application that allows rendering in the
background using offscreen p_buffers.
This application uses many OpenGL features
and extensive texturing.
When I run this application iconified and in
the background, by itself, where it is rendering
lot of frames written to disc, it works fine, that
is all output is as expected.
However, since this process takes some time,
the actual reason for implementing offscreen
rendering was to allow the user to start up a separate
instance of the application, where
the user could do her other work, managing textured symbols
and other interactive OpenGL rendering.
This also includes using a lot of different OpenGL functions,
but at interactive rates (no offscreen p_buffer in use).
However, when the rendering process is minimized and
the interactive process is used while rendering,
the textures used in the background process tend
to be corrupted, that is they many times disappear completely,
but only some of them (there is always some texturing in each frame).
I can't understand that the presence of another application using
OpenGL resources such as texturing can influence my background process.
And, yes, I am using GLX_PRESERVED_CONTENTS_SGIX
for my p_buffer, and it's contents are OK, only that
some textures are missing.
This is all on an Octane (O2 runs the same application fine)
IRIX 6.5.4 on Octane MXE, R10K.
This seems like a bug to me, but of course I might have
overlooked something. Has anyone seen anything like
this before?
I appreciate any help,
Torgeir
