Listing the "Blender Foundation" as copyright holder implied the Blender
Foundation holds copyright to files which may include work from many
developers.
While keeping copyright on headers makes sense for isolated libraries,
Blender's own code may be refactored or moved between files in a way
that makes the per file copyright holders less meaningful.
Copyright references to the "Blender Foundation" have been replaced with
"Blender Authors", with the exception of `./extern/` since these this
contains libraries which are more isolated, any changed to license
headers there can be handled on a case-by-case basis.
Some directories in `./intern/` have also been excluded:
- `./intern/cycles/` it's own `AUTHORS` file is planned.
- `./intern/opensubdiv/`.
An "AUTHORS" file has been added, using the chromium projects authors
file as a template.
Design task: #110784
Ref !110783.
A lot of files were missing copyright field in the header and
the Blender Foundation contributed to them in a sense of bug
fixing and general maintenance.
This change makes it explicit that those files are at least
partially copyrighted by the Blender Foundation.
Note that this does not make it so the Blender Foundation is
the only holder of the copyright in those files, and developers
who do not have a signed contract with the foundation still
hold the copyright as well.
Another aspect of this change is using SPDX format for the
header. We already used it for the license specification,
and now we state it for the copyright as well, following the
FAQ:
https://reuse.software/faq/
Use a shorter/simpler license convention, stops the header taking so
much space.
Follow the SPDX license specification: https://spdx.org/licenses
- C/C++/objc/objc++
- Python
- Shell Scripts
- CMake, GNUmakefile
While most of the source tree has been included
- `./extern/` was left out.
- `./intern/cycles` & `./intern/atomic` are also excluded because they
use different header conventions.
doc/license/SPDX-license-identifiers.txt has been added to list SPDX all
used identifiers.
See P2788 for the script that automated these edits.

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`.
Differential Revision: https://developer.blender.org/D8466
The changes come from the `functions` branch, where I'm using
these structures a lot.
This also includes a new `BLI::Optional<T>` type, which is similar
to `std::Optional<T>` which can be used when Blender starts using
C++17.
Some users of the 3D versions were storing 2D data in it.
Using a 3D tree for 2D data adds a spatially redundant branch
every 3rd level, as well as some extra memory use, best avoid this.
This moves logic into kdtree_impl.h which is included in a source
file that defines the number of dimensions - so we can easily support
different numbers of dimensions as needed
(currently 3D and 4D are supported).
Macro use isn't so nice but avoids a lot of duplicate code.
Logic to for boids to avoid head-on collisions was in BLI_kdtree.
Move this into a callback which is now defined in boids.c
so the kdtree code can be kept generic.
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.
This performs a range search on the kdtree, running a callback instead of allocating an array.
Allows the caller to perform extra checks in the case of overlap,
avoids redundant array allocations, since caller can handle matches.
* Fix crash entering particle mode, and particles not showing.
Janne, please check the changes I made in psys_cache_paths,
I'm not confident they are correct.
* Fix some warnings
Too many new features to list! But here are the biggies:
- Boids can move on air and/or land, or climb a goal object.
- Proper interaction with collision objects.
* Closest collision object in negative z direction is considered as ground.
* Other collision objects are obstacles and boids collide with them.
- Boid behavior rules are now added to a dynamic list.
* Many new rules and many still not implemented.
* Different rule evaluation modes (fuzzy, random, average).
- Only particle systems defined by per system "boid relations" are considered for simulation of that system.
* This is in addition to the boids own system of course.
* Relations define other systems as "neutral", "friend" or "enemy".
- All effectors now effect boid physics, not boid brains.
* This allows forcing boids somewhere.
* Exception to this is new "boid" effector, which defines boid predators (positive strength) and goals (negative strength).
Known issue:
- Boid health isn't yet stored in pointcache so simulations with "fight" rule are not be read from cache properly.
- Object/Group visualization object's animation is not played in "particle time". This is definately the wanted behavior, but isn't possible with the current state of dupliobject code.
Other new features:
- Particle systems can now be named separately from particle settings.
* Default name for particle settings is now "ParticleSettings" instead of "PSys"
- Per particle system list of particle effector weights.
* Enables different effection strengths for particles from different particle systems with without messing around with effector group setting.
Other code changes:
- KDTree now supports range search as it's needed for new boids.
- "Keyed particle targets" renamed as general "particle targets", as they're needed for boids too. (this might break some files saved with new keyed particles)
Bug fixes:
- Object & group visualizations didn't work.
- Interpolating pointcache didn't do rotation.
=========
Merge of the famous particle patch by Janne Karhu, a full rewrite
of the Blender particle system. This includes:
- Emitter, Hair and Reactor particle types.
- Newtonian, Keyed and Boids physics.
- Various particle visualisation and rendering types.
- Vertex group and texture control for various properties.
- Interpolated child particles from parents.
- Hair editing with combing, growing, cutting, .. .
- Explode modifier.
- Harmonic, Magnetic fields, and multiple falloff types.
.. and lots of other things, some more info is here:
http://wiki.blender.org/index.php/BlenderDev/Particles_Rewritehttp://wiki.blender.org/index.php/BlenderDev/Particles_Rewrite_Doc
The new particle system cannot be backwards compatible. Old particle
systems are being converted to the new system, but will require
tweaking to get them looking the same as before.
Point Cache
===========
The new system to replace manual baking, based on automatic caching
on disk. This is currently used by softbodies and the particle system.
See the Cache API section on:
http://wiki.blender.org/index.php/BlenderDev/PhysicsSprint
Documentation
=============
These new features still need good docs for the release logs, help
for this is appreciated.
