- 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.
calling
bpy.ops.wm.read_factory_settings()
... would clear a scripts namespace if running directly, not in a module.
Fix by backing up and restoring the __main__ module.
Also found BKE_reportf wasnt printing all reports in background mode as BKE_report() was doing.
- bpy.data.*.load() functions were only accepting UTF-8 paths.
- rna functions/properties now accept byte values rather then strings for file paths.
- bpy.path.resolve_ncase now supports byte objects.
- multiplying a 2D vector by a 3x3 or 4x4 matrix would use un-initialized memory, now throw an exception.
- use more variable length array BLI_math functions.
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.
- invalid dimension type could be passed without raising an error.
- negative dimensions could crash blender, now they raise errors.
- zero length dimension arg was not detected.
- floating point lengths were accepted, now only allow ints.
also comment unused vars.
- rna array parsing was using PySequence_Size() in a loop, this can be slow to run so only call once.
- assigning a single value to a multi-dimensional array was missing type check.
- improve exception messages for rna array type errors.
- simplify vector slice assignment by using mathutils_array_parse(...)
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.
