Matlab z buffer for simulating kinect

Question

We are trying to simulate simple kinect output.

I have rendered a triangle mesh in Matlab and now I want to get at the depth buffer of the figure/axis where the shape has been rendered. How do I do that in matlab? i.e. how do I access the depth buffer of a figure?

I have done something similar where I wrote a raycasting algorithm to simulate such output. It never really worked too well (very slow on large meshes). I'd be interested to know if you can get it directly from a figure, as this would be much easier... – Swaziland

I guess your real question is how to get access to the JOGL objects used by MatLab's own figures? – Aube

That sounds like a good way to phrase it. I didnt realize Matlab figures were JOGL objects. – Amperehour

Could any one find the solution of this problem ? – Lowder

@Ben Voigt, are you sure that they are JOGL objects and not JFrame objects? Does Matlab necessarily use OpenGL? Is there a chance it uses direct canvas drawing instead? In either case the question is still open and I have left a 300 bounty on it.#8862967 – Amperehour

@twerdster: I know MatLab uses OpenGL for rendering. I don't know which wrapper it uses, could be JOGL, could be something else. – Aube

Answer 1

You could try this.

Unfortunately thats not what we are looking for at all. We need a per pixel depth value for the current figure output. – Amperehour
