- use NULL rather then 0 where possible (makes code & function calls more readable IMHO).
- set static variables and functions (exposed some unused vars/funcs).
- use func(void) rather then func() for definitions.
- modifier code was using sizeof() without knowing the sizeof the array when clearing the modifier type array.
- use BLI_snprintf rather then sprintf where the size of the string is known.
- particle drawing code kept a reference to stack float values (not a problem at the moment but would crash if accessed later).
- 'axis' arg was not coerced from a tuple like other args now do.
- 'axis' arg was being modified in-place (VERY BAD).
- also made new function matrix_3x3_as_4x4().
- comparing eulers was ignoring the order.
- printing Euler()'s now prints the order too.
- un-orderable types (all except for Vector's), were not raising an exception when compared with >=, >, <, <=.
each accept Euler/Quaternion/Matrix types.
eg:
Euler.rotate(Quaternion(axis, angle))
Vector.rotate(Euler((pi/2, 0, 0)))
matrix.resize_4x4() and euler.make_compatible() were still returning an instance of themselves, now return None.
The plane which defined the shear had the factor applied to each axis equally.
This meant that the shear for any 3x3 or 4x4 matrix would be diagonal on the positive values of each axis.
Only being able to create diagonal shear matrices seems stupid, now take a pair of floats for the shear factor corresponding to the plane axis values, so its possible to shear on only one axis of the plane.
rotation range clamping used a while loop which would run forever when the value was so big subtracting a full revolution didnt change the value.
Solve by using fmod() and double precision angle.
(should have made this change along with the others).
Matrix([1, 2], [3, 4]) --> Matrix(([1, 2], [3, 4]))
This is so adding initialization args works right.
Also simplify initialization code (re-use slice assignment).
The main advantage with this is that its close to twice as fast to do 'vertex.co[:]' then 'tuple(vertex.co)', this is common for writing a vertex array.
the correct python behavior in this case is to return a copy of the original type, however euler and quats don't support different sizes so we cant do so easily.
- pep8 script was giving an error on non utf8 scons source files.
- use PyList_SET_ITEM macro when list type is ensured.
- all mathutils types use subtypes to create new types when available.
- use defines MAT3_UNITY, MAT4_UNITY to initialize unit matrices.
- 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.
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.
- 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.
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.
- 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.
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.
- 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.
