VTM render 3D Model

[Longri, Andre Höpfner]

Hi

I have seen that it give a 3D model from a tree. 

This 3D Model are loaded on org.oscim.test.gdx.poi3d.Poi3DLayer but with run Gdx3DTest it will never show!  

Any suggestion to show a 3D Model on a Layer! 

My Target is to render a 3D Model on my own position, like this:

Are you sure?
Here is a screenshot from Gdx3DTest (see the tile coordinates).

Thanks for fast answer.
I will check again with this coordinates.

Ok, you are right, the trees will be render!

So please give me a hint to set the right transformation to a 3D object that I can see this object on my location.

Ok, I have found the LocationOverlay! But this has Android dependency’s!

Maybe it will be better to move it from ‘vtm-app’ to ‘vtm’ ?

And interface all platform dependency’s like compass!

The important part is its LayerRenderer.

I'll check it later for how to make it more modular and improve its implementation (opened #171).

I have played with LocationOverlay and have a little problem with the shader program.

On Mac desktop I become a shader compile error with first line!

"precision mediump float;"

When I delete this line, so on Mac it will be render fine!

Do you have an idea, how to detect Mac?

So I can replace this line if I running on Mac!

[Emux]

To recognize a macOS in Java (or you mean iOS ?) could be done with something like:

boolean isMac = System.getProperty("os.name").toLowerCase(Locale.ENGLISH).contains("mac");

But eventually we better find why this simple call causes trouble..

BTW we can increase also here the shader precision to 'highp', but I have to perform tests before pushing any changes.

For general issues we can add a new GDX_MAC_QUIRKS boolean in GLAdapter like the other ones.

I pushed a standalone LocationRenderer in 'vtm' module #171.

With many improvements and needed fixes for working properly.
You can see its api in use at 'vtm-app'.

I also activated all fragment shaders.
We can create even more creative renders. :)

I added in #171 screenshots of the two location shaders.

This looks good and I will certainly use, but my goal is a 3D model to draw.

Now I have tried the Poi3DLayer.java analyze, but unfortunately http://www.opensciencemap.org/ is straight down and in Maps Forge maps, there is no static 

...

final day TREE_TAG = new Day ("natural", "tree");

...

Also, in the maps of openandromaps, there are no trees. Do you have a map in the trees, I can use offline?

Both the site and the vector tiles are offline..

I see Mapsforge tag-mapping doesn't have the natural=tree, so the built maps in our server.

I remember we had removed it some time ago, since they tend to fill all over the map.

You can still build a map file with a modified tag-mapping and trees.

now I use TREE_TAG = new Tag("highway", "bus_stop");

It's easier !
