While it might be handy to have type-less functionality which is
similar to how C++ math is implemented it can not be easily achieved
with just preprocessor in a way which does not have side-effects on
wrong usage.
There macros where often used on a non-trivial expression, and there
was at least one usage where it was causing an actual side effect/bug
on Windows (see change around square_f(sh[index++]) in studiolight.c).
For such cases it is handy to have a function which is guaranteed to
have zero side-effects. The motivation behind actually removing the
macros is that there is already a way to do similar calculation. Also,
not having such macros is a way to guarantee that its usage is not
changed in a way which have side-effects and that it's not used as an
inspiration for cases where it should not be used.

The BVHTree was erroneously marked as not cached.

Accidentally unused in rB7c3bbe93aaa2
|
|
The stored value was always false because of shadowing.
Also disable unused code.

With this function it is easier to create and have control over editmeshes `BHVtree`s.
|
|
This is a step that allow using `bvh_cache` for `EditMeshe`s.
|
|
It was a stupid mistake with the wrong pointer being referenced.
It was a serious problem because the memory leak was considerable.
|
|
I'm not very fond of adding new types of bvhtrees.
But this is probably the most efficient solution.

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.

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This is often invalid, outdated or misleading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.

Free the BVH tree immediately along with the mesh, otherwise we might access
invalid mesh data.

There is no point having operations that iterate over the whole
bit array as macros, so convert BLI_BITMAP_SET_ALL to a function.
Also, add more utilities for copying and manipulating masks.

Helps separate variable names from descriptive text.
Was already used in some parts of the code,
double space and dashes were used elsewhere.

multiple objects.
- Use the object referenced in `BMEditMesh` as the `ghash` key to save the bvhtrees in cache;
- Create a boundbox around edit_mesh to test the snap before creating bvhtree;
- Save the `edit_mesh`s bvhtree in the mesh bvh_cache;
This is a part of the D3504.

This prevents zero-leafs bvhtrees from being recalculated multiple times.

loose edges

Same issue as in DM-based on, so follow up of rBf3efa9e15f58...

Could lead to atempt to free NULL pointer, and/or memory leak.
|
|
BLI_bvhkdop functions were not made to work with zero-leaf trees.
Perhaps a better solution would be to modify BLI_bvhkdop to work with zero leaf trees.
But this solution of returning NULL was already used for bvhtrees of looptris.

This member currently doubles the value of `ray->radius` or is not even used.

with `bvhtree_from_mesh_get`.
|
|
This will help us have more control over bvhtrees that are cached.
