2015-05-02Drop accumulation bufferLars-Dominik Braun1-60/+19
Unused after dropping spatial/temporal filters. Cuts memory usage in half.
2015-05-02Drop progress printing from rendering threadLars-Dominik Braun7-203/+36
2015-05-02Drop fieldLars-Dominik Braun6-31/+12
2015-05-02Drop temporal filter/passesLars-Dominik Braun11-619/+18
2015-05-02Drop oversamplingLars-Dominik Braun8-137/+15
Just scale it down.
2015-05-02Move iter_storage allocation to thread functionLars-Dominik Braun2-28/+24
2015-05-02Prefetch bucket accumulatorLars-Dominik Braun2-12/+14
The bucket add is a hotspot.
2015-05-02Use rotation matrixLars-Dominik Braun4-26/+60
Reuse affine transformation code from variations.
2015-05-02Factor out genome printfLars-Dominik Braun1-10/+9
Fixes -random’s output.
2015-05-02Move width/height options from render to randomLars-Dominik Braun1-29/+63
flam3’s design is a little wonky here. An explicit bounding box in the flame’s coordinate system would help.
2015-05-02random: Adjust bounding boxLars-Dominik Braun1-0/+34
2015-05-02render: Add width/height command line optionsLars-Dominik Braun1-3/+33
2015-05-02Factor out palette interpolationLars-Dominik Braun5-41/+47
2015-05-02Vectorize color clippingLars-Dominik Braun11-166/+143
Replaces redundant code with one function. Oddly this fixes rendering with earlyclip – not sure why. Drop transparency and channel settings (always transparent, always four channels).
2015-05-02render: Add oversample argumentLars-Dominik Braun1-1/+13
2015-05-02Use floating point color values in [0,1]Lars-Dominik Braun4-40/+37
Internal color representation is [0,1] now for every channel.
2015-05-02Remove all uses of getenvLars-Dominik Braun6-213/+14
Not much functionality lost here. Move on.
2015-05-02Drop unused png read functionLars-Dominik Braun1-108/+0
2015-05-02Improve command line interfaceLars-Dominik Braun22-3289/+443
Initial arguments-based cli, replacing the three tools -animate, -genome and -render with just one. Still need to get rid of most calls to getenv.
2015-05-02Fix memory leaksLars-Dominik Braun1-2/+3
Introduced by 15f89a8390af9338227c2ee3f603b32a1a206a8f
2015-05-02Correctly align malloc’d vector arraysLars-Dominik Braun2-4/+17
Fixes segfault with -march=native
2015-05-02Support clang vector attributeLars-Dominik Braun1-0/+9
2015-05-02Vectorize accumulationLars-Dominik Braun8-178/+97
Also vectorizes some color functions and switches to double accumulation buffer. Does not seem to be slower.
2015-05-02Drop density estimatorLars-Dominik Braun9-545/+22
First of all, it does not look too pretty. But more importantly now we can reduce the bucket size to four (instead of five) and vectorize that stuff.
2015-05-02Remove unused variables, fix compiler warningsLars-Dominik Braun7-20/+11
2015-05-02Switch rng seed to /dev/urandomLars-Dominik Braun2-13/+12
2015-05-02Unify prng useLars-Dominik Braun19-433/+373
Finally drop all isaac references, do not use system rng any more. Drop rng state from flam3_frame – it was not used anyway.
2015-05-02Fix fuse iterationsLars-Dominik Braun1-1/+1
Bug introduced by commit 37b8237136afee2d47d3899b87a3bafdc40acce3
2015-05-02Drop striped renderingLars-Dominik Braun4-174/+35
The amount of memory available is not a problem anymore.
2015-05-02Drop support for jpeg/netpbm outputLars-Dominik Braun6-206/+6
2015-05-02Drop unused, exported functionsLars-Dominik Braun6-709/+19
2015-05-02Drop Windows/Mac support, require pthreadsLars-Dominik Braun12-279/+6
2015-05-02Drop support for atomic ops and bucket formatsLars-Dominik Braun3-257/+2
Atomic ops are slower than locks, probably going to switch buckets to uint64_t later.
2015-05-02Fix curve variationLars-Dominik Braun1-2/+2
2015-05-02Vectorize flam3_iterateLars-Dominik Braun4-52/+51
2015-05-02Vectorize c and post matrices as well apply_xformLars-Dominik Braun8-74/+66
2015-05-02Bugfixes for variations vectorizationLars-Dominik Braun1-5/+5
2015-05-02Explicit input coordinatesLars-Dominik Braun2-392/+389
Slower, obviously.
2015-05-02Vectorize variantsLars-Dominik Braun2-657/+562
Slightly worse with amdlibm, slightly better with gcc’s builtins (no optimization) and worse with optimization
2015-05-02Move to wafLars-Dominik Braun14-3001/+43
2015-05-02Declare variation functions staticLars-Dominik Braun2-220/+107
2015-05-02Fix compiler warningLars-Dominik Braun1-1/+1
2015-05-02Remove autoconf stuff from gitLars-Dominik Braun21-50796/+13
2015-05-02Replace isaac with xorshiftLars-Dominik Braun14-271/+79
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 Braun65-0/+0
2015-02-15Modified for libpng 1.5 API support.Erik Reckase1-14/+14
