29df776b89 optimization: call one bmesh operator for rotate (not 3). 
added pivot_m4() utility function since rotating about an arbitrary point is handy.

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.

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.

533f359c0d code cleanup: some style edits, also allow mul_v2_m2v2() to have the same value as in-out, since this is a convention for existing matrix functions. 2013-02-12 00:35:31 +00:00

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 ;)

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.

e5d0dcb8d8 Few cleanup in matrix mathutils (make mul_m3_m3m4 and mul_m4_m3m4 consistant with other similar funcs, mainly copy-safe [i.e. you can use the same matrix as operand and result, saves lines in some already over-complicated code!]). 2012-09-16 15:25:28 +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.

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.
