728b713d86 use more BLI math functions. 2010-08-15 15:14:08 +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.

fdfb46337c - Use vector interpolation functions from math_vector module in
curve subdivision operator.
- Added function interp_v4_v4v4().

07b547980d remove unused includes for blenlib, left ifdef's for non linux os's alone. 2010-03-20 18:52:03 +00:00

8ec59c7c68 Math Lib:
* inline some more functions, from math_base and math_vector
* also made some changes to the way inline is done so it can
  work for more than one file
* reflect_v3_v3v3 requires input vectors to be normalized now.
* added rgb_to_grayscale
* added zero_v4, copy_v4_v4, swap_v4_v4, is_one_v3
* added box_clip_bounds_m4 to clip a bounding box against a
  projection matrix

fde4686d77 barycentric transform utility geometry function.
From 2 triangles and 1 point, the relative position between the point and the first triangle is applied to the second triangle to find the target point.
the barycentric weights are calculated in 2D space with a signed area so values outside the triangle bounds are supported.

wrapped by python:
 pt_to = Geometry.BarycentricTransform(pt_from, t1a, t1b, t1c, t2a, t1b, t1c)

NOTE: 
- moved some barycentric weight functions out of projection painting into the math lib.
- ended up making some of the math functions use const args.
TODO:
- support exceptional cases. zero area tries and similar.

8cce609a04 Missing angle_v3v3 definition (it was declared)
Wrong definition for angle_v2v2 (it read 2d vectors as 3d vectors)

b83751d8c2 Math Lib: merging over some changes from the sculpt branch:
* swap v2/v3
* multiply-and-add (madd) v3
* inline v3 short/float conversion
* mul_v3_m3v3

bd1f548d8e fix for [#19655] Curve is a disaster
when changing curve twist I assumed 2D curves would not need dir or quat values set, however these are used when getting a path from a curve.
also added interp_v3_v3v3v3v3

385875632d Math Lib
* Fix remaining issues before conversion.
* Inline various vector functions, currently enabled for all platforms.
  I expect this to work in GCC/MSVC at least, if other platforms don't
  support it, #ifdef's can be added.

60ea745613 Math Lib Reorganization
* New header and source files.
* Still need a few tweaks before switching code to use them.
