[net.graphics] Profiling 3D rendering systems

pete@utcsrgv.UUCP (P. Schoeler) (06/28/84)

Does anyone out there know of any work on profiling  3D graphics rendering 
packages ? I'm interested in particular on how much time is spent in each 
phase of the process :
* geometric transformations
* hidden surface removal
* antialiasing
* shading
* texture mapping etc ...
Results would of course depend on the type and complexity of the image
as well as a million or so other factors, but that's what makes it
interesting ...

In the case of our "render" program, most of the time is spent in shading
calculations.  We spend very little time in hidden surface calculations,
since we use a Z-buffer type approach.  Anti-aliasing takes some fraction,
but is highly optimized.
