- I would guess a Watcom compiled version run through a decent code optimiser
- would have a significant effect, as indeed would support for a Weitek copro
- (which I don't have, alas).
-
- I haven't been through the code in detail, but there must be a few loops
- that could be unwound a little. The sluggishness comes from multiplatform
- code I guess.
-
- I have heard of a Watcom version of POV, but so far been unable to track one
- down, a nice chap said he would mail me one, but his address was rejected
- by his domain's postmaster... :-(
-
- Cheers
- Andy.
