I read lots of information about getting depth with fragment shader. such as http://www.opengl.org/discussion_boards/ubbthreads.php?ubb=showflat&Number=234519
I\'m writing a 2d game in OpenGL ES 1.0 (with casts to 1.1 Extensions where applicable). I\'m trying to keep this as generic as possible in case I\'ve missed something obvious.
I\'m on Android OpenGL-ES 2.0 and after all the limitations that come with it, I can\'t figure out how to take 2D screen touches to the 3D points I have. I can\'t get the right results.
I\'d like to retrieve the depth buffer from my camera view for a 3D filtering application. Currently, I\'m using glReadPixels to get the depth component. Instead of the [0,1] values, I need the true v
I can\'t seem to read the depth buffer values in OpenGL ES2 on iOS 4.3 afDepthPixels = (float*)malloc(sizeof(float) * iScreenWidth * iScreenHeight);
I am doing a ray-casting in a 3d texture until I hit a correct value. I am doing the ray-casting in a cube and the cube corners are already in world coordinates so I don\'t have to multiply the vertic
I saw many examples on the web (for example) which do the following Create and Bind FBO Create and Bind BUFFERS (texture, render, depth, stencil)

I\'m rendering my scene to a texture. This works fine except that depth testing does not work. How do I enable depth testing if rendering to an offscreen texture? I\'m using the FrameBuffer class http
