4f4bd27512 bugfix [#24665] mathutils.Matrix initialization is counter-intuitive and generates bugs
was printing transposed, also nicer printing.

>>> from mathutils import Matrix
>>> Matrix()
Matrix((1.0, 0.0, 0.0, 0.0),
       (0.0, 1.0, 0.0, 0.0),
       (0.0, 0.0, 1.0, 0.0),
       (0.0, 0.0, 0.0, 1.0))

was...
Matrix((1.000000, 0.000000, 0.000000, 0.000000), (0.000000, 1.000000, 0.000000, 0.000000), (0.000000, 0.000000, 1.000000, 0.000000), (0.000000, 0.000000, 0.000000, 1.000000))

a34f525a21 bugfix [#24660] (vector * matrix) fails, (matrix * vector) succeeds
- Reverse vector * matrix multiplication order. now this matches how numpy works.
- Disallow 'matrix * vec' and 'quat * vec', now it raises an error.
- Add missing in-place multiply 'vec *= quat'

Many scripts will need to be updated for this but at least it will error rather then failing silently.

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()

be32cf8b32 UNUSED() macro so -Wunused-parameter can be used with GCC without so many warnings.
applied to python api and exotic.c, removed some args being passed down which were not needed.

keyword args for new mathutils types were being ignored when they should raise an error.

1be4eda552 bugfix [#23454] vector*matrix not the same as vector*=matrix
- they now share the same code so it wont happen again.
- added id_data to properties so we can do...
  matrix = C.object.matrix_world
  obj = matrix.owner.id_data # get the original object back.

0be08725ad Py API (GSoC): Second merging commit
Rough summary of fixes/changes:
- Blender Py API: GameLogic -> bge.logic
- Blender Py API: Implemented missing KX_PYATTRIBUTE_TODOs and -DUMMYs.
- Fix for [#22924] KX_PolygonMaterial.diffuse does not return expected list[r,g,b]
- Py API: Renaming _owner attribute of mathutils classes to owner.
- Fix some minor errors in mathutils and blf.
- Enabling game engine autoplay again based on a patch by Dalai:
  * The biggest 3D view in the open scene is used, if there is none, blender opens the file normally and raises an error.
  * The 3D view are is made fullscreen.
  * Quad view, header, properties and toolbox panel are all hidden to get the maximum view.
  * If the game engine full screen setting is set, the game starts in fullscreen.
- Fix for ipo conversion on file transition in the game engine.

556b615cf8 mathutils module methods only contained matrix constructors, move these to matrix class methods since this is acceptable in python. eg: dict.fromkeys() and groups them more logically.
mathutils.RotationMatrix -> mathutils.Matrix.Rotation
 mathutils.ScaleMatrix -> mathutils.Matrix.Scale
 mathutils.ShearMatrix -> mathutils.Matrix.Shear
 mathutils.TranslationMatrix -> mathutils.Matrix.Translation
 mathutils.OrthoProjectionMatrix -> mathutils.Matrix.OrthoProjection

Changing " **type** " into "\n\n:type: " in Mathutils, to have like "type: float" in its own line.

f9fbfd9297 oversight in recent mathutils update. obj.matrix = obj.matrix would call its own updage callbacks until it crashed. 2010-04-27 18:55:25 +00:00

6bb55fd93e py/rna, euler objects order is now wrapped correctly...
eg:
 eul = bpy.context.object.rotation_euler
 eul.order = 'XZY' # will update the objects setting.

4fc4fb9bfb rna/python mathutils module
- return euler rotation values from rna now have correct rotation order.
- mathutils.Euler stored rotation order off by 1. (didnt work at all)
- Euler/Quat/Color sliceing working again.

182587fce1 [#22045] Memory leak in Mathutils.Matrix
own fault when adding mathutils callbacks, generic destructor didnt free the matrix accessor array, made the array apart of the matrix struct since its not worth malloc'ing to save at most 16bytes.

67cfc427ee PyAPI
- added new mathutils.Color() type, use with rna so we can do for eg:
 material.diffuse_color.r = 1.0
 # also has hsv access
 material.diffuse_color.s = 0.6

 - made Mathutils and Geometry module names lowercase.

fe9a22a018 py api file rename
- prefix mathutils api.
- 2 blf.c files (annoying for debugging)
- py api docs ignore keying sets as with operators.
