This is for design task T67744, Boolean Redesign.
It adds a choice of solver to the Boolean modifier and the
Intersect (Boolean) and Intersect (Knife) tools.
The 'Fast' choice is the current Bmesh boolean.
The new 'Exact' choice is a more advanced algorithm that supports
overlapping geometry and uses more robust calculations, but is
slower than the Fast choice.
The default with this commit is set to 'Exact'. We can decide before
the 2.91 release whether or not this is the right choice, but this
choice now will get us more testing and feedback on the new code.

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

Clang Tidy reported a couple of false positives. I disabled
those `NOLINTNEXTLINE`.

The 'random' unit tests and some examples from the new boolean code
triggered asserts and crashes. This fixes those.
There is a new flag in the input that optionally disables a pass
over input to snap segment edges to other segments.

This 'fixes' T68554: 'API mathutils.geometry.tessellate_polygon returns
bad results sometimes' by documenting the limitations of the current
implementation.
I've also added a unit test for the function, so that any change in this
behaviour will get noticed.
No functional changes.

This computation is complex and useful enough to expose the existing
C math utility used by BVH nearest to Python. Otherwise this requires
the use of intersect_point_tri and multiple intersect_point_line calls
with some added vector math.

Use mathutils_array_parse which converts any sequence of numbers.
|
|
Use fixed normal for 2D input, no need to calculate it.

Provides Python API access to recently added Constrained Delaunay
Triangulation routine.

Apply clang format as proposed in T53211.

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

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.

BF-admins agree to remove header information that isn't useful,
to reduce noise.
- BEGIN/END license blocks
Developers should add non license comments as separate comment blocks.
No need for separator text.
- Contributors
This is often invalid, outdated or misleading
especially when splitting files.
It's more useful to git-blame to find out who has developed the code.
See P901 for script to perform these edits.

`mathutils.geometry.barycentric_transform` used `tri_a[1-3]` for the
target triangle, but in fact they are `tri_b[1-3]`

Some of these API's can have 3D versions, explicitly name them 2D.

This was meant to be generic but introduced possible type errors
and unnecessary complication.
Replace with typed PyC_Tuple_PackArray_* functions.
Also add PyC_Tuple_Pack_* macro which replaces some uses of
Py_BuildValue, with the advantage of not having to parse a string.

Ugly issue really, but at least doc now matches behavior of the function. :|

This could cause problems since they could be any int,
then passed directly to internal functions that assume bools.

Fixed/enhanced a few usages of `mathutils_array_parse()` in this file actually...
|
|
Dummy typo, we need a 3D vector here...

This appends while giving ownership to the list, avoiding temp assignment.
This matches PyList_SET_ITEM which bypasses refcount's
Note, this also reduce code-size, Py_DECREF is a rather heavy macro.

Setting all values of a tuple is such a common operation that it deserves its own macro.
Also added Py_INCREF_RET to avoid confusing use of comma operator.

Trivial, safe for final 2.73.

remove 'type' argument, very few mathutils objects are wrapped,
add new function for creating wrapped objects.
also fixes unlikely memory leak if the data-array can't be allocated.

Previously this only supported tri/quads,
now arbitrary size poly lines are supported.
|
|
Previously only vector args were accepted,
now allow generic sequence of numbers.
Was annoying to create vectors just to pass in args.
