The problem is caused by a lack of prediction in the `isect_line_segment_tri_v3`
that incorrectly confirms some intersections of coplanar segments to the triangle.
The solution is to use another algorithm to detect intersections.
This also resulted in a slight improvement in the performance:
- 1min 17sec to 1min 6sec in my test file

This replaces header include guards with `#pragma once`.
A couple of include guards are not removed yet (e.g. `__RNA_TYPES_H__`),
because they are used in other places.
This patch has been generated by P1561 followed by `make format`.

Having includes in debug builds makes it possible to accidentally
break release builds.
Avoid this by moving calls to other modules out of BLI_assert.h
into BLI_assert.c

Also order return matrices last.

Covers basics like generation of new UUID.
Also contains code needed to use the SessionUUID as a key in the Map.

These precision issues were evident in corrected uvs when the option
`"Correct Face Attributes"` is enabled.

The name was misleading as it returns true whenever it intersects the
line represented by the points.

Implementation of lerp without a function requires repeating one of
the arguments, which is not ideal. To avoid that, add a new function
to the driver namespace. In addition, provide a function for clamping
between 0 and 1 to support easy clamped lerp, and a smoothstep function
from GLSL that is somewhat related.
The function implementations are added to a new bl_math module.
As an aside, add the round function and two-argument log to the
pylike expression subset.

Currently if you drag and drop an item from the outliner elsewhere in
the Blender window, the outliner will scroll the entire time, even if the
mouse is far away. This commit adds optional behavior for the edge pan
operator that makes it only act if the mouse is close enough to the region.

Thanks to Campbell for pointing this out.

Those are useful when you have to create containers with static
storage duration. If those would use Blender's guarded allocator,
it would report memory leaks, that are not actually leaks.
|
|
This still cannot be controlled by the user. Currently, all particles are
killed after two seconds

This updates the usage of integer types in code I wrote according to our new style guides.
Major changes:
* Use signed instead of unsigned integers in many places.
* C++ containers in blenlib use `int64_t` for size and indices now (instead of `uint`).
* Hash values for C++ containers are 64 bit wide now (instead of 32 bit).
I do hope that I broke no builds, but it is quite likely that some compiler reports
slightly different errors. Please let me know when there are any errors. If the fix
is small, feel free to commit it yourself.
I compiled successfully on linux with gcc and on windows.

This should be used whenever you rely on the fact, that the
returned pointer points to the beginning of a null-terminated array.

Those are defined exactly as their corresponding functions in Cycles.
|
|
The same function is also used by cycles.

The move constructor of `mpq_class` from GMP currently
allocates when it is moved. So, it cannot be noexcept.
Since we want to use this type, this static assert cannot
stay there.

Clang-tidy reported that those parameters could be const,
but that is not true on windows.

shobjidl_core.h only exists in the windows 10 SDK in the 8.1
SDK ShObjIdl.h will have the definitions we need, which still
exists in the 10 SDK and implicitly includes shobjidl_core.h.
so ShObjIdl.h will work on both SDK versions.

I don't see the need for a BVH Tree to have root but not have leafs.
But apparently this case is possible.
|

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

This adds `blender::RandomNumberGenerator` in `BLI_rand.hh`.
Furthermore, `RNG` is now implemented in terms of this new generator.
No functional changes are expected, the generated random numbers
are not changed by this commit.

This makes adding to the end of a linked list simpler,
In most cases we avoid this in favor of BLI_linklist_append.
For one off operations it's OK.

This allows us to avoid many calls to `as_span()` methods. I will
remove those in the next commit. Furthermore, constructors
of Vector and Array can convert from one type to another now.
I tested these changes on Linux with gcc and on Windows.

This is not necessary in C++17 anymore.

This can be used to find separate islands in meshes efficiently (as is
done in cycles already). Furthermore, this helps to implement some
algorithms on node trees more efficiently.
