Original code by @mano-wii, modified for general use.
|
|
These platforms didn't see maintenance in years.
This commit just removes ifdef's & cmake check.
|
|
Replace iroundf with round_fl_to_int, add other types
|
|
|
|
Only lock tri's facing different directions.
Needed because scanfill creates zero area faces.
|
|
mistakenly considering the state as degenerated"
This reverts commit a8f11f5422afa01608817755eea310e987f896be.
Result is no longer symmetrical, will investigate a different fix.

|
|
|
This allows to have different macro headers without them sharing
similar names to regular C modules.
|
|
Some error checks weren't being done in both directions
when calculating the best split direction for a quad.
|
|
|
|
Integer division that floors on negative output (like Python's).
|
|
Needed for 3D iterative edge-rotation to avoid flipping when projected
from different angles,
but could keep zero area faces in 2D polygons.
|
|
|
|
Also use assert w/ rotate_m4.
|
|
|
|
|
|
Was already used in two other headers, remove underscore prefix.
|
|
So we can use in headers without pulling in many other defines.
|
|
Includes a version that takes a separator and macros for convenience.
|
|
Useful when ghash keys are reallocated.
|
|
This exposes end-point bias argument, needed in rare cases.
|

This will allow much finer controll over how we copy data-blocks, from
full copy in Main database, to "lighter" ones (out of Main, inside an
already allocated datablock, etc.).
This commit also transfers a llot of what was previously handled by
per-ID-type custom code to generic ID handling code in BKE_library.
Hopefully will avoid in future inconsistencies and missing bits we had
all over the codebase in the past.
It also adds missing copying handling for a few types, most notably
Scene (which where using a fully customized handling previously).
Note that the type of allocation used during copying (regular in Main,
allocated but outside of Main, or not allocated by ID handling code at
all) is stored in ID's, which allows to handle them correctly when
freeing. This needs to be taken care of with caution when doing 'weird'
unusual things with ID copying and/or allocation!
As a final note, while rather noisy, this commit will hopefully not
break too much existing branches, old 'API' has been kept for the main
part, as a wrapper around new code. Cleaning it up will happen later.

Tweak the bias from the previous fix a bit to be more backwards compatible in
some scene. In the end which way we round is quite arbitrary, but keeping the
case where the texture coordinate is exactly zero the same seems better.
|
|
Solution is to bias the coordinates a little, same as Cycles checker texture.
|
|
|
|
Also remove duplicate & mismatching comments from grease-pencil header.
Keep comments close to implementation to avoid getting out of sync.
|
|
Use for calculating the angle between 2 directions on an axis.
Also signed version and normalized plane projection,
use when input is normalized.
|
|
|
|
Allow to quickly enable print & tree verify.
|
|
Single axis version of mat3_from_axis_conversion,
when the second axis isn't important (orienting an arrow for eg).
|
|
This leads to a crash in 2.8, but commiting here.
Patch by Campbell Barton.
|
|
This is handy to have C++ guards for BLI functions so they
can be easily re-used in C++ code. This matches other headers
from this library as well.
|

The idea is to accumulate all new tasks in a thread local queue
first without doing any thread synchronization (aka, locks and
conditional variables) and move those tasks to a scheduler queue
once they are all ready. This way we avoid per-task-pool lock
and only have one lock per bunch of tasks.
This is particularly handy when scheduling new dependency graph
node children. Brings FPS of cached simulation from the linked
below file from ~30 to ~50.
See documentation for BLI_task_pool_delayed_push_{begin, end}
and for TaskThreadLocalStorage::do_delayed_push.
Fixes T50027: Rigidbody playback and simulation performance regression with new depsgraph
Thanks Bastien for the review!

|
|
Those are not depsgraph or C++ specific and can be used by everyone.
|
|
This way everyone can benefit from it, not only dependency graph.

The Issue
=======
For a long time now MinGW has been unsupported and unmaintained and at this point,
it looks like something that we should just leave behind and move on.
Why Remove
==========
One of the big motivations for MinGW back in the day is that it was free compared to MSVC which was licensed based.
However, now that this is no longer true we have basically stopped updating the need CMake files.
Along with the CMake files, there are several patches to the extern libs needed to make this work. For example, see:
https://developer.blender.org/diffusion/B/browse/master/extern/carve/patches/mingw_w64.patch
If we wanted to keep MinGW then we would need to make more custom patches to the external libs and
this is not something our platform maintainers are willing to do.
For example, here is the patches needed to build python: https://github.com/Alexpux/MINGW-packages/tree/master/mingw-w64-python3
Fixes T51301
