- 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.

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.

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 ;)

make sure its valid. also remove some commented code (more then one generation of bmesh old).

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.

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.

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.

to BLI_math_matrix

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.
|
|
Separated it into two functions so now it'll be clear if check happens for
orthonormal or just orthogonal.
|
|
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.

without the underscores these clogged up the namespace for autocompleation which was annoying.

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:

This branch adds mostly organizational improvements to the node system by renaming the node folders and files. A couple of internal features have been added too.

strings & pedantic warnings.
also minor rename in bvh export
|

- python/mathutils api matrix.lerp(other, factor)
- new function mat3_to_rot_size(), like mat4_to_loc_rot_size but with no location.
|
|
|
|
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()
|

|
|
- 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.

BOP_DEBUG, which was used inconsistently, and had to add a define for superlu.
|
|
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!.

* 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.
|
|
* 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.

access Matrix.is_negative
renamed Mathutils attribute wrapped -> is_wrapped
|
|
* swap v2/v3
* multiply-and-add (madd) v3
* inline v3 short/float conversion
* mul_v3_m3v3
|
|
* 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.
|
|
* New header and source files.
* Still need a few tweaks before switching code to use them.
