76e989d7b1 function renaming for own recently added BLI_math functions, suggested by Brecht. 2013-07-30 10:58:36 +00:00
5dc3cfc983 fix [#36282] Spin error with non uniform scale
add support for passing object matrix to bmesh transform operators.
2013-07-26 11:15:22 +00:00
29df776b89 optimization: call one bmesh operator for rotate (not 3).
added pivot_m4() utility function since rotating about an arbitrary point is handy.
2013-07-26 06:12:49 +00:00
ec8d277c64 BLI_math rename functions:
- mult_m4_m4m4 -> mul_m4_m4m4
- mult_m3_m3m4 -> mul_m3_m3m4

these temporary names were used to avoid problems when argument order was switched.

89c8de1f48 add matrix multiply for projection that outputs 2d values. 2013-05-08 12:55:36 +00:00
4a7feafa49 Support object scale for mesh display options. (currently only uniform scale for thickness test) 2013-04-17 23:30:19 +00:00
ae58968e0a Blender Internal Render in viewport
Because of our release soon, feature has been added behind the Debug Menu.
CTRL+ALT+D and set it to -1. Or commandline --debug-value -1.

When debug set to -1, you can put the viewport to 'render' mode, just like
for Cycles. Notes for testers: (and please no bugs in tracker for this :)

- It renders without AA, MBlur, Panorama, Sequence, Composite
- Only active render layer gets rendered. Select another layer will re-render.
- But yes: it works for FreeStyle renders!
- Also does great for local view.
- BI is not well suited for incremental renders on view changes. This only
  works for non-raytrace scenes, or zoom in ortho or camera mode, or for 
  Material changes. In most cases a full re-render is being done.
- ESC works to stop the preview render.
- Borders render as well. (CTRL+B)
- Force a refresh with arrow key left/right. A lot of settings don't trigger
  re-render yet.

Tech notes:

- FreeStyle is adding a lot of temp objects/meshes in the Main database. This
caused DepsGraph to trigger changes (and redraws). I've prepended the names
for these temp objects with char number 27 (ESC), and made these names be
ignored for tag update checking.

- Fixed some bugs that were noticable with such excessive re-renders, like 
  for opening file window, quit during renders.

fcbd9c3a33 Old bug fix: Uv smart stitch failed to detect angle if islands were
rotated close to 180 degrees and there were edges both below and above
the 180 degree threshhold. Separating and averaging the negative and
positive angles seems to solve the issue making the tool a bit more
robust ;)

2eab18dc32 code cleanup: use const for matrix functions vector args. 2013-02-09 07:14:42 +00:00
2b875a947f skip calculating the normal for each face when triangulating, all callers make sure its valid. also remove some commented code (more then one generation of bmesh old). 2013-01-29 15:05:23 +00:00
e83e3b0cf7 math: Add functions to decompose transformation matrices
mat4_decompose() is similar to mat4_to_loc_rot_size() but returns
rotation as quaternion.
mat4_to_loc_quat() just returns location and rotation without size.

071a43f754 Fix #33497: seting object scale to 0 on one axis made moving verts in edit mode
impossible. In this case matrix inversion failed and didn't give a useful result.
Now it falls back to a pseudoinverse in that case, so that moving along the
other axes still works.

There may be other places that can benefit from this, but this is a place where
it has no significant performance impact, doing this in general for e.g. bone
matrices could be quite slow.

f727448e10 fix [#33106] Decimate modifier/collapse give bad result
FLT_EPSILON was too small to use when checking if the edge collapse result is an error.

add invert_m3_m3_ex(), invert_m3_ex() functiosn which take an epsilon to check the determinant, saves calculating it twice per edge collapse.

dbb40e805d py api: add mathutils.Matrix adjugate(d) methods, also add adjoint_m2_m2() to BLI_math_matrix 2012-10-29 03:36:55 +00:00
9892736206 code cleanup: header cleanup and remove some duplicate defines. 2012-05-12 20:39:39 +00:00
6527f42b6b Fix #31193: Normals don't have any Z component
Issue was caused by heavily non-uniform scale applied on object.
Run scale correction on face and vertex normals draw if there's non-uniform scale.
2012-05-01 11:01:24 +00:00
26b0255049 Fix for is_orthogonal check which in fact was checking for orthonormal matrix.
Separated it into two functions so now it'll be clear if check happens for
orthonormal or just orthogonal.
2012-04-01 00:14:41 +00:00
c6d80d1db1 Fix ##30455: Orthographic grid alignment jumps/shifts when zooming
Issue was caused by precision errors with floats.
Made internal grid drawing stuff using doubles and also added some
functions to multiply double vector by float matrix which also makes
all intermediate calculation in doubles.

95670e03a0 style cleanup / comment formatting for bli/bke/bmesh 2012-03-03 20:19:11 +00:00
2b7ca2304a unify include guard defines, __$FILENAME__
without the underscores these clogged up the namespace for autocompleation which was annoying.

3311164b24 Math lib: matrix multiplication order fix for two functions that were
inconsistent with similar functions & math notation:

mul_m4_m4m4(R, B, A) => mult_m4_m4m4(R, A, B)
mul_m3_m3m4(R, B, A) => mult_m3_m3m4(R, A, B)

For branch maintainers, it should be relatively simple to fix things manually,
it's also possible run this script after merging to do automatic replacement:

149955b3e2 print_m3/m4 didnt use const char *, which gave an errror with passing strings & pedantic warnings.
also minor rename in bvh export
2011-01-06 13:49:09 +00:00
f781780cc0 - blend_m3_m3m3 and blend_m4_m4m4 now support matrices with negative scales.
- python/mathutils api matrix.lerp(other, factor)
- new function mat3_to_rot_size(), like mat4_to_loc_rot_size but with no location.
2010-11-22 10:39:28 +00:00
a44f4dd400 dont use const for matrix arg, since it needs to be cast in most cases. 2010-10-26 20:41:16 +00:00
f8ec6b8654 move matrix decomposition out of object.c into BLI_math_matrix function: mat4_to_loc_rot_size(), use this now for pchan_apply_mat4() to support negative scale, visual keying now uses compatible eulers.
also added access to this in python's mathutils.Matrix()
 loc, quat, scale = matrix.decompose()

6540bb1375 Add some missing const's 2010-10-22 10:17:55 +00:00
2fe940f8df Fix for snapping pose bones with axis-angle rotation.
- armature_mat_pose_to_bone() was missing axis-angle check.
- added loc_axisangle_size_to_mat4() for completeness.
- use 'const' prefix where possible in math rotation functions.

58683fa993 enable DEBUG define in CMake and scons, also change booleans debug option to BOP_DEBUG, which was used inconsistently, and had to add a define for superlu. 2010-10-18 11:21:22 +00:00
7db9558cf6 bugfix [#24291] Error parenting a child with any negative scaling coordinate
the bug was in object_apply_mat4(), caused by applying a non-normalized matrix to the rotation.
Blender 2.4x also had this problem, surprising nobody noticed!.

30a7c6d281 Merge a few small blenlib changes from the render25 branch:
* define for missing hypotf on msvc.
* svd_m4 and pseudoinverse_m4_m4 functions.
* small tweak to perlin noise, use static function instead of macro.
* BLI_linklist_find and BLI_linklist_insert_after functions.
* MALWAYS_INLINE define to force inlining.

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.

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.
2009-11-10 19:13:05 +00:00
60ea745613 Math Lib Reorganization
* New header and source files.
* Still need a few tweaks before switching code to use them.
