View Full Version : The innards of area coverage for anti-aliasing

Hi All,

I'll keep this one rather short:

Does anyone know of a document, white paper, spec or anything along those lines that describes the *exact* calculation of area coverage figures for anti-aliasing when using GL_POLYGON / LINE / POINT_SMOOTH ?

The red book says "The details of calculating coverage values are complex, are difficult to specify in general...." (Version 1.2, 3rd Ed, page 234). That's about all I have been able to find after detailed searching.

(This information is required as part of physics-based research, otherwise I would just run with multisampling!!)

Thx.
