This patch is from erik85, who says:
This patch makes populate_plane inside polymesh_from_trimesh_with_dissolve run in parallel.
On a test file with a boolean between two subdivided cubes (~6 million verts) this gives a 10% speed increase (49.5s to 45s) on my 6 core CPU.
Also there is an optimization of other_tri_if_manifold to skip the contains-call and get the pointer directly.
This reduces CPU time for find_patches from 5s to 2.2s on the same test file.
|
|
When there are many components (separate pieces of connected mesh),
a part of the algorithm to determine component containment was slow.
Using a float version of finding the nearest point on a triangle
as a prefilter sped this up enormously. A case of 25 icospheres
subdivided twice goes 11 seconds faster on my Macbook pro with this
change.

This corrects an outdated comment in the vector header and a typo
in the index mask header.

This is from patch D11432 from Erik Abrahamsson. He found that
in some mpq3 functions called frequently from loops, passing in
buffers for termporary mpq3 values can save substantial time.
On my machine, his example in that patch went from 9.48s to 7.50s
for the boolean part of the calculation. On his machine, a running
time went from 17s to 10.3s.

The fseek() function on Windows only accepts a 32-bit long offset
argument. Because of this we have our own version, BLI_fseek(), which
will use 64-bit _fseeki64() on Windows. This patch just replaces some
fseek() calls with BLI_fseek().

This patch from Erik Abrahamsson uses a parallel_for to speed up
the case where the input is not manifold and the "hole_tolerant"
option is set.
In a test case on a 24 core (48 thread) machine, this sped up a
the boolean part on an object with 221k triangles from 12.06s to 0.46s.

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.

This patch fixes a long-standing complaint from users:
the console window shortly flashing when they start
blender.
This is done by adding a new executable called
blender-launcher.exe which starts blender.exe while
hiding the console.
Any command line parameters given to blender-launcher
will be passed on to blender.exe so it'll be a drop
in replacement.
Starting blender.exe on its own will still function as
a proper console app so no changes required here for
users that use blender for batch processing.
Notable changes:
Registering blender (-R switch) will now register
blender-launcher as the preferred executable.
This patch updates the installer and updates the
shortcuts to start blender-launcher.exe rather
than blender.exe

Colors are often thought of as being 4 values that make up that can make any color.
But that is of course too limited. In C we didn’t spend time to annotate what we meant
when using colors.
Recently `BLI_color.hh` was made to facilitate color structures in CPP. CPP has possibilities to
enforce annotating structures during compilation and can adds conversions between them using
function overloading and explicit constructors.
The storage structs can hold 4 channels (r, g, b and a).
Usage:
Convert a theme byte color to a linearrgb premultiplied.
```
ColorTheme4b theme_color;
ColorSceneLinear4f<eAlpha::Premultiplied> linearrgb_color =
BLI_color_convert_to_scene_linear(theme_color).premultiply_alpha();
```
The API is structured to make most use of inlining. Most notable are space
conversions done via `BLI_color_convert_to*` functions.
- Conversions between spaces (theme <=> scene linear) should always be done by
invoking the `BLI_color_convert_to*` methods.
- Encoding colors (compressing to store colors inside a less precision storage)
should be done by invoking the `encode` and `decode` methods.
- Changing alpha association should be done by invoking `premultiply_alpha` or
`unpremultiply_alpha` methods.
# Encoding.
Color encoding is used to store colors with less precision as in using `uint8_t` in
stead of `float`. This encoding is supported for `eSpace::SceneLinear`.
To make this clear to the developer the `eSpace::SceneLinearByteEncoded`
space is added.
# Precision
Colors can be stored using `uint8_t` or `float` colors. The conversion
between the two precisions are available as methods. (`to_4b` and
`to_4f`).
# Alpha conversion
Alpha conversion is only supported in SceneLinear space.
Extending:
- This file can be extended with `ColorHex/Hsl/Hsv` for different representations
of rgb based colors. `ColorHsl4f<eSpace::SceneLinear, eAlpha::Premultiplied>`
- Add non RGB spaces/storages ColorXyz.

This patch turns off the creation of file thumbnails for files that are
offline and therefore not fully-present on the file system. These types
of files - typically cloud-based or stored on slower backup media -
only have their contents available when actually accessed, at which
point there will be a short delay. If we allow thumbnail creation in
this state then all offline files in a folder will be downloaded just
to view a listing, which can take a long time.
Files in this state will instead get a more generic thumbnail that
still indicates file type (icon in center) and that shows offline state
will a special icon at the bottom-left.
Although this currently only affects Windows users, most of this patch
is platform-agnostic. So other platforms inherit this behavior if they
only add FILE_ATTR_OFFLINE attribute to files in this state.
See D11101 for more information.

Heterogeneous lookup is useful when constructing a key in a
map/set is relatively expensive (e.g. `std::string`). When doing
lookups in the map/set, one usually does not want to construct
the type to avoid overhead. Instead, heterogeneous lookup
allows for using a different type (such as `StringRef`) as key.
This change makes it easier to implement heterogeneous
lookup for custom types. Before, one had to specialize
`blender::DefaultHash`. Now, one just has to implement
a `static uint64_t hash_as(value)` on the type itself.
One still has to provide the equality operator in addition
to the hash function of course.
|
|
Sometimes it is useful to find the key that compares equal
to a known key. Typically that happens when the key itself
has additional data attached that is not part of its hash.
Note that the returned key reference/pointer is const, because
the caller must not change the key in a way that changes its
hash or how it compares to other keys.

The wrapper is necessary to support building without TBB.
This class is used by the upcoming new evaluator for

Previously, one could allocate an array, but not construct its

This patch adds initial curve support to geometry nodes. Currently
there is only one node available, the "Curve to Mesh" node, T87428.
However, the aim of the changes here is larger than just supporting
curve data in nodes-- it also uses the opportunity to add better spline
data structures, intended to replace the existing curve evaluation code.
The curve code in Blender is quite old, and it's generally regarded as
some of the messiest, hardest-to-understand code as well. The classes
in `BKE_spline.hh` aim to be faster, more extensible, and much more
easily understandable. Further explanation can be found in comments in
that file.
Initial builtin spline attributes are supported-- reading and writing
from the `cyclic` and `resolution` attributes works with any of the
attribute nodes. Also, only Z-up normal calculation is implemented
at the moment, and tilts do not apply yet.
**Limitations**
- For now, you must bring curves into the node tree with an "Object
Info" node. Changes to the curve modifier stack will come later.
- Converting to a mesh is necessary to visualize the curve data.
Further progress can be tracked in: T87245

There was a quadratic algorithm extracting triangles from a coplanar
cluster. This is now linear.
Also found and fixed a bug in the same area related to the triangulator
added recently: it didn't get the right correspondence between new
edges and original edges.

While it was technically safe to call Map.remove while iterating over
a map, it wasn't really designed to work. Also it wasn't very efficient,
because to remove the element, the map would have to search it
again. Now it is possible to remove an element given an iterator
into the map. It is safe to remove the element while iterating over
the map. Obviously, the removed element must not be accessed
anymore after it has been removed.
|
|
This is useful for an upcoming commit that allows removing
an element based on an iterator.
|
|
This adds two new methods:
* `clear` just removes all keys from the vector set.
* `index_of_or_add` returns the index of a key and adds it if has not
been added before.

Sometimes functions expect a span instead of a virtual array.
If the virtual array is a span internally already, great. But if it is
not (e.g. the position attribute on a mesh), the elements have
to be copied over to a span.
This patch makes the copying process more efficient by giving
the compiler more opportunity for optimization.
|

In some cases functions were defined with arguments of different array
lengths in headers vs. implementations. This commit fixes some of the
cases I ran into, but probably not all of them.

The old version was correct as well but did a move even when not necessary.

This is convenient because having a uniform interface is nice, and
because of the similarity to "last".

This method is similar to `std::vector::emblace_back` in that it constructs
the new object inplace in the vector, removing the need for a move.
The `_as` suffix is consistent with similar behavior in Map and Set data structures.
