Hi all,
Just wondering why hsv2rgb.pd (which is pretty incomprehensible) isn't a compiled external. I had to write a C implementation because the Pd implementation was too slow. Some rough benchmarks:
CPU: 1.6GHz Pentium-M Patch: rather complex, with 25*1024 calls to hsv2rgb per second. CPU-load as reported by load-meter.pd: hsv2rgb.pd : 108% fast_hsv2rgb.c : 94%
Quite a difference.
Note that fast_hsv2rgb.c is coded really unsafely, doesn't check argument counts/types/ranges/etc - use at your own risk.
Thanks,
Claude
