- It is my understanding that ANSI is once more interested in this

- sugested addendum.

-
- dunno
- Applying a cell array to uv parameter space for NURBS might be one option...
-
- The Evans&Sutherland implementation has had antialiasing for a while.
- The DEC implementation supports it only on harware that supports it.
- Both do it as escapes. There is no support for antialiasing in the ISO
- standard.

-
- I will comment on OpenGL once an implementation has actually been
- released. In the mean time, I will continue using PHIGS and PEX, as I
- cannot program with promises.

-
- Yes I believe so. Try archie
