Ton Roosendaal	8d940dfafe	Random() issues with rendering... ... - AO and soft shadow AreaLight tables were generated without fixed seed, causing animations to give unwanted amounts of noise. - Made sure these tables now are calculated before render, with fixed seed - Then found out the BLI_rand() has very bad seeding... it showed up as patterns. After some experimenting, found a nice method using noise.c hash tables. For compatibility with old code, named it BLI_srandom() to use this next to the BLI_srand(). This follows libc rand() and random() naming convention. - Then of course threading should work... so made a BLI_thread_rand version of the calls. Now supports up to 16 threads, comments added in .h and .c Result is stable animation render with AO and soft shadow. But, please test and feedback!	2005-08-25 13:11:04 +00:00

Daniel Dunbar	40a5ed791d	- added RNG abstract random object rng_{new/free/seed/get{Int,Double,Float}} ... to avoid use of global generator. at the moment the renderer owns the number generator and this is important for retaining render consistency.	2005-07-25 20:33:10 +00:00

Kent Mein	f1c4f705a1	Removed the config.h thing from the .h's in the source dir. ... So we should be all set now :) Kent -- mein@cs.umn.edu	2002-12-27 13:11:01 +00:00
Kent Mein	b9a19f1ea7	Did all of the .h's in source ... (adding) #ifdef HAVE_CONFIG_H #include <config.h> #endif also the Makefile.in's were from previous patch adding the system depend stuff to configure.ac Kent -- mein@cs.umn.edu	2002-11-25 11:16:17 +00:00
Kent Mein	01bff70383	fixed spacing in the headers to get rid of some warnings and some other ... little minor spacing issues.	2002-10-30 02:07:20 +00:00
