Minimum Z depth

The TMinZDepthComposite uses depth values in zBuffers to determine whether or not to replace the destination color. When the source z-Buffer value is less than the destination zBuffer value, the destination color is replaced; otherwise, it is left as is.

This transfer mode is independent of a color space, and is used to assemble a 3D scene from individually rendered elements. For example, you can use this class to take a 3D rendered view of an office, and a separate 3D rendered view of a sphere to copy only the unobstructed portions of the sphere onto the office.
