mat4_to_eul & mat3_to_eul are already working this way.
Without this we get problems with constraints, eg:
rotation on the Y axis over 90d can be represented by setting the X and Z to -PI, Y would decrease to 0 (infact 180d).
- 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.
Examples.
euler = Euler(1, 2, 3)
euler.order = 'ZXY'
euler = matrix.to_euler('XZY')
Still missing rna support. this still wont give the right order, defaulting to XYZ.
eul = object.rotation_euler
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.
* 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.
