Detailed Description

Depth buffer in OpenGL format provided by an application, enabling NVIDIA IndeX to do depth-correct compositing with a rendering performed by the application.

The depth buffer must be be in normalized unsigned integer format. It can be retrieved with an OpenGL call such as:

glReadPixels(0, 0, width, height, GL_DEPTH_COMPONENT, GL_UNSIGNED_INT, buffer);
