Difference between W- and Z-Buffer

[fragiskos]

General question:
What is the difference between W- and Z-Buffer (like in the Glide plugin)?

Which one provides more quality?

 

[Gonetz]

For voodoos, w-buffer uses floating-point depth values and z-buffer uses fixed point ones. Thus, z-buffer is a bit faster, but less precise. Unfortunately, I can't always use w-buffer in glide64 due to some hardware limitations.

Thanks for the info, Gonetz!
