These are two examples that use both an FBO and a pbuffer to read back depth buffer values in a Producer::Camera postDrawCallback. They are both a "single shot" snapshot of the depth buffer saved to an .rgb image. I've included the PBuffer example as it is a lot less code.

Have you tried a CameraNode post draw callback?

I'll let Don do his promotional bit for Producer::Camera.
