2015-05-02Remove unused variables, fix compiler warningsLars-Dominik Braun1-2/+0
2015-05-02Unify prng useLars-Dominik Braun1-6/+6
Finally drop all isaac references, do not use system rng any more. Drop rng state from flam3_frame – it was not used anyway.
2015-05-02Drop Windows/Mac support, require pthreadsLars-Dominik Braun1-60/+4
2015-05-02Drop support for atomic ops and bucket formatsLars-Dominik Braun1-26/+0
Atomic ops are slower than locks, probably going to switch buckets to uint64_t later.
2015-05-02Vectorize flam3_iterateLars-Dominik Braun1-10/+12
2015-05-02Replace isaac with xorshiftLars-Dominik Braun1-4/+1
No difference in performance. rdrand instruction alone is too slow.
2015-05-02Fix crashLars-Dominik Braun1-3/+2
For some reason filter is overwritten by pthread_join, removing its second argument fixes the problem. It is unused anyway.
2015-05-02Move out of subdirLars-Dominik Braun1-0/+1287
