afb4b65167 Random number generator: replace a bunch of usage of the global random number
generator with a local one. It's not thread safe and will not give repeatable
results, so in most cases it should not be used.

Also fixes #34992 where the noise texture of a displacement modifier was not
properly random in opengl animation render, because the seed got reset to a
fixed value by an unrelated function while for final render it changed each
frame.

101660c809 code cleanup: give rng functions BLI prefix. 2012-10-23 13:50:44 +00:00
9892736206 code cleanup: header cleanup and remove some duplicate defines. 2012-05-12 20:39:39 +00:00
7bbf4b7831 style cleanup
- spelling - turns out we had tessellation spelt wrong all over.
- use \directive for doxy (not @directive)
- remove BLI_sparsemap.h - was from bmesh merge IIRC but entire file commented and not used.

2b7ca2304a unify include guard defines, __$FILENAME__
without the underscores these clogged up the namespace for autocompleation which was annoying.

b97ad119b9 doxygen: add blenlib under core as module. 2011-02-18 13:58:08 +00:00
9a85013692 Merge various small changes from render branch:
* Division by zero fix for TNT SVD code.
* Sound fix, in case ffmpeg decode fails, don't use the samples.
* Fix for incorrect bounds of transformed objects in new raytracing code.
* Gave memory arena's a name used for allocations for easier memory
  usage debugging.
* Dupligroup no_draw option was using layers but not restrict view/render
  setting. (not a bugfix exactly but would do display list context switching
  while drawing for no reason).
* Fix objects instanced on hair particles not giving consistent results
  when the object is transformed.
* New math functions: madd_v4_v4fl, len_squared_v3v3, interp_v4_v4v4v4,
  mul_v4_m4v4, SH and form factor functions, box_minmax_bounds_m4.
* mul_m4_m4m4 and mul_m3_m3m3 now accept the same pointers for multiple
  arguments.
* endjob callback for WM jobs system.
* Geometry node uv/color layer now has search list/autocomplete.
* Various small buildsystem tweaks, not strictly needed yet in trunk.

d5a890c078 a) New unified effector system by Janne (jahka) + Me (genscher): particle and cloth/sb don't use different systems anymore. b) cloth wind corrected for new system c) Wind has noise option now d) @ Bjornmose: since the old factors are gone SB doesn't need to divide by 1000 etc. anymore. I didn't want to touch your code - you might like to take a look at it :) 2008-08-18 11:09:27 +00:00

5d0a207ecb Patch from GSR that a) fixes a whole bunch of GPL/BL license
blocks that were previously missed; and b) greatly increase my
ohloh stats!

32a8b4f8e6 Particles
=========

- Fix crash in particle transform with the particle system not editable.
- Particle child distribution and caching is now multithreaded.
- Child particles now have a separate Render Amount next to the existing
  Amount. The render amount particles are now only distributed and cached
  at render time, which should make editing with child particles faster.

- Two new options for diffuse strand shading:
	- Surface Diffuse: computes the strand normal taking the normal at
	  the surface into account.
	- Blending Distance: the distance in Blender units over which to
	  blend in the normal at the surface.
- Special strand rendering for more memory efficient and faster hair and
  grass. This is a work in progress, and has a number of known issues,
  don't report bugs to me for this feature yet.

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!

3dcc653365 - mixed up RNG type definition 2005-07-25 20:56:48 +00:00
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.

ba28fc489a - added an array shuffling function to BLI_rand 2005-07-20 03:33:44 +00:00
f1c4f705a1 Removed the config.h thing from the .h's in the source dir.
So we should be all set now :)

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

01bff70383 fixed spacing in the headers to get rid of some warnings and some other
little minor spacing issues.
