Just wondering, I'd like to get something I made in jME to output to the screen in the form of a depthmap rather than standard 3D graphics. By a depthmap I mean, a greyscale view where the furthest away from the viewpoint are black and the closest to the viewpoint are white - ignoring all textures. Is this at all possible? I wouldn't even know where to start :oops:
Cheers if anyone can help 
Also, in any simplegame you can see an example of this by pressing one of the function keys… F2 maybe? Don't recall off the top of my head.
Hello everyone.
I admit, this topic is not exactly new, but I nevertheless have some questions. I want to render the scene as a depthmap only (i. e. replacing the usual output). What is the best method to achieve that? At the moment, I have a render method that looks like this:
@Override
public void render(float tpf) {
super.render(tpf);
if (showDepthMap) {
Renderer r = DisplaySystem.getDisplaySystem().getRenderer();
r.renderQueue();
Debugger.drawBuffer(Texture.RenderToTextureType.Depth, -1, r, 100);
}
}
This is more or less taken from the SimpleGame example. Unfortunately, it's not exactly possible to replace the existing scene by the depthmap-only-scene this way. I'd have to rewrite or copy drawBuffer for it. But is this the way to go?
