This reverts commit 41e650981861c2f18ab0548e18851d1d761066ff.
This broke "CubeMaskFirst" test.
Any value even slightly outside the [-1.0..1.0] range
caused the result to be nan, which can happen when calculating
the dot-product between two unit length vectors.
|
|
The clamped version of acos isn't needed as degenerate (nan) coordinates
result in zeroed vectors which don't need clamping.

This patch makes us less restrictive on the allowed types of FreeType
font character maps we allow, rather than primarily unicode-only. This
allows us to use some legacy, symbol, specialty, and proprietary fonts
like Wingdings. Note we were a little less restrictive with vfonts,
used for 3D Text Objects, so this patch primarily helps VSE.
See D12124 for details and examples.

When displaying the names of fonts for 3D Text objects, use the same
format as shown in File Browser: Family name + Style name. They are
currently shown with Postscript Name, which doesn't match well.

`r_left`, `r_right`, `r_bottom` and `r_top` were ignoring `clip_near` value

Also rename `projmat` to `winmat` in these cases.

Fix division by zero when `BKE_bone_parent_transform_invert()` inverts a
scale vector with zero components.
Zero values in the to-be-inverted vector are now simply skipped, i.e.
remain zero after inversion. This at least ensures that
`invert_v3_safe(invert_v3_safe(vector))` results in the same vector.
This commit does NOT fix the conceptual problem that an inversion of a
potentially non-invertible vector is relied upon. It just avoids the
division by zero.

For T78995 we want to change the data structure of keylists to
improve performance. (Probably a Vector with bin-search capabilities).
This patch hides the internal structure of the keylists behind `AnimKeylist`
structure. This allows us to change the internals without 'breaking' where it is
being used.
The change adds functions to create, free, find and walk over the
keylist.

When `BLI_task_parallel_mempool` does not use threading, the
`userdata_chunk` is allocated locally simulating a TLS.
However `func_reduce` is not called so the original chunk is ignored.
`task_parallel_iterator_no_threads` is another function that doesn't call
`func_reduce`. It also ignores `userdata_chunk_local` in the main iterator.
The solution in these cases is not to create a `userdata_chunk_local`.
This fixes T90131

Calculate frequency of time/frame label drawing, such that labels have
at least 10px margin and don't overlap.
Change timecode format:
- Use at least `mm:ss` format
- Don't display frames if all labels would end with +00

Add three functions that trim characters from the front & end of a
`StringRef`. All functions return a new `StringRef` that references a
sub-string of the original `StringRef`.
- `trim(chars_to_remove)`: strips all characters from the start and end
that occur in `chars_to_remove`.
- `trim(char_to_remove)`: same, but with a single character to remove.
- `trim()`: remove leading & trailing whitespace, so same as
`trim(" \r\n\t")`

The old modifier code, now just used for Fast, has code in it to
flip faces of arguments when their tranform's negativity differs
from the main object's transform's negativity.
I had neglected to put that logic in when I made the change that
skipped the round trip through BMesh.
Fixing this means that the results are more what the user expects
when some or all operands have negative scales.

This might change the rotation of some instances after a Curve to Points.
Unfortunately, there is not much we can do about that, the math before
was just wrong. The forward and up axis stayed the same though.

When the new "need_ids" flag is false and the output type is not
one of the valid BMesh kinds, there is no need to propagate even
a dummy id to all of the faces.

These used their own ad-hoc syntax.

The test forgot to set the new need_ids field, which luckily
exposed a bug in the C api for delaunay when that field is false.
Fixed the bug and the test, and added a test for the need_ids false
case.

Some uses of delaunay_2d_calc don't need to know the original verts,
edges, and faces that correspond to output elements.
This change adds a "need_ids" value to the CDT input spec, default true,
which tracks the input ids only when true.
The python api mathutils.geometry.delaunay_2d_cdt gets an optional
final bool argument that is the value of need_ids. If the argument
is not supplied, it is true by default, so this won't break old uses
of the API.
On a sample text test, not tracking ids save about 30% of the runtime.
For most inputs the difference will not be so dramatic: it only really
kicks in if there are a lot of holes.

From Erik Abrahamsson, this uses parallel loops for raycasting.
It speeds up one example with many crossings of a bezier curve,
from 0.68s to 0.28s.

Using part of a patch from Erik Abrahamsson, this replaces the
use of linked lists for original id tracking by Sets.
I had thought that the lists were unlikely to grow to more than
a few elements, but when the mesh has a lot of holes (whose
original ids go *outside* the hole, and therefore, most of the
mesh), this assumption can be very wrong.
On a Text regression test, the time went from 11.67s to 0.16s
with this fix. I also tested to make sure that Boolean didn't
slow down with this, and found it actually had a very slight speedup.
Using Sets exposed a dependency on the ordering of the items
in the id lists, luckily caught by a mesh intersect regression test,
so fixed that.
