Hi!
Has anyone tried to compile Povray with VectorC? (www.codeplay.com)
Would be nice to see if it could speed things up a litle.

Vector processing features like MMX and 3D-Now only work for integer or
single precision float values. POV-Ray uses mostly double precision
floats, and can not benefit very much from these features.

I don't see your point...MMX still won't accelerate POV-Ray to any
noticeable degree, because POV uses double precision floats for most
things. It does use single precision floats for colors, but most of the
work is done with doubles.
And since this isn't POV code, I don't see how optimizing it has
anything to do with optimizing POV...

What are you replying to here, Chris? Did someone cancel the originals?

A message that went into a discussion of optimizing a function for
copying bit maps. I think it was based on some sample code for writing
stuff to take advantage of MMX with the VectorC compiler, it used colors
stored as structs of char variables.

Apparently so...
