Mathutils types were always GC tracked even when it wasn't intended.
Not having to track objects speeds up Python execution.
In an isolated benchmark created to stress test the GC
creating 4-million vectors (re-assigning them 100 times), this gives
an overall ~2.5x speedup, see: P3221.
Details:
Since [0] (which added support for sub-classed mathutils types)
tp_alloc was called which defaults to PyType_GenericAlloc which always
GC tracked the resulting object when Py_TPFLAGS_HAVE_GC was set.
Avoid using PyType_GenericAlloc unless the type is sub-classed,
in that case the object is un-tracked.
Add asserts that the tracked state is as expected before tracking &
un-tracking, to ensure changes to object creation don't cause objects
to be tracked unintentionally.
Also assign the PyTypeObject.tp_is_gc callback so types optionally GC
track objects only do so when an object is referenced.

While both are supported, 'arg' is in more common use so prefer it.

Making the callers responsible for this isn't practical as matrices are
often passed indirectly to a functions such as mat3_to_axis_angle,
BKE_object_mat3_to_rot & BKE_pchan_mat3_to_rot.
Or the matrix is combined from other matrices which could be negative.
Given quaternions calculated from negative matrices are completely
invalid and checking only needs to negate matrices with a negative
determinant, move the check into mat3_to_quat and related functions.
Add mat3_normalized_to_quat_fast for cases no error checking on the
input matrix is needed such as blending rotations.
|
|
The result of mat3_normalized_to_quat isn't valid for negative matrices.
Isolate the fix to the Matrix.to_quaternion() instead of changing
mat3_normalized_to_quat to prevent unintended side effects elsewhere.
|
|
Add a convenient way of checking if the matrix is an identity matrix.
|
|
Also minor improvements & corrections to comments.

Use a shorter/simpler license convention, stops the header taking so
much space.

While most of the source tree has been included
- `./extern/` was left out.
- `./intern/cycles` & `./intern/atomic` are also excluded because they

There was no convenient way to check if the owner
of a mathutils type was valid.
Added to support issue reported in T91111.

While doxygen supports both, conform to our style guide.

Event though in practice this wasn't causing problems as the fixed size
buffers are generally large enough not to truncate text.
Using the result from `snprint` or `BLI_snprintf` to step over a fixed
size buffer allows for buffer overruns as the returned value is the size
needed to copy the entire string, not the number of bytes copied.
Building strings using this convention with multiple calls:
ofs += BLI_snprintf(str + ofs, str_len_max - ofs);
.. caused the size argument to become negative,
wrapping it to a large value when cast to the unsigned argument.

Combining location, rotation and scale channels into a matrix is
a standard task, so while it is easily accomplished by constructing
and multiplying 3 matrices, having a standard utility allows for
more clear code.
The new constructor builds a 4x4 matrix from separate location,
rotation and scale values. Rotation can be represented as a 3x3
Matrix, Quaternion or Euler value, while the other two inputs
are vectors. Unneeded inputs can be replaced with None.

Replace deprecated _PyUnicode_AsString{AndSize} usage.
T83626 still needs to be resolved before 3.10 is usable.

This addresses warnings from Clang-Tidy's `readability-else-after-return`
rule in the `source/blender/python` module.
No functional changes.

This was disabled during 2.8x for smooth porting of 2.7x scripts,
Now '@' is used for matrix multiplication,
support '*' to multiple vector elements.

For some reason there seems to be no way to do the very simple and
obvious task of converting a scale vector to a matrix via mathutils.
The Matrix.Scale constructor does something complicated instead.

Mostly functions wrapping args, not confirming to our style guide.

While \file doesn't need an argument, it can't have another doxy

Move \ingroup onto same line to be more compact and
make it clear the file is in the group.

Needed for clan-format not to wrap onto one line.
