- Does anyone out there know how FractalWitchcraft achieves its speed?
- I was completely stunned at the time it took FW to generate the example
- image (Lightning...) in comparison to Fractint 17.2 with no floating point
- and guessing:
- Fractint 17.2: ca. 2h15min
- FW: ca. 20sec
- (486-33)
-
- I've figured that FW's speed cannot result from the way it builds up the
- screen. First of all, there is nearly no difference between edge tracing on
- and off. Also, I believe the little pseudo-tesseral thing it does can't be
- credited for the speed (it doesn't even recognize larger areas of single
- color). I think FW must have some speedup in the core iteration loop, mainly
- because it seems nearly unaffected by iteration limit variations.
- Anybody got more info?
-
- Thanks
