License Headers: Set copyright to "Blender Authors", add AUTHORS 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.

File headers: SPDX License migration 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.

Add a skeleton of C API for Eigen3. Title says pretty much everything. For now, only thing available is a solver of eigen values/vectors for self-adjoint matrices. We can easily add more when needed. Thanks to Sergey and Campbell for quick review. 2015-07-13 17:40:06 +02:00

Math: optimizations for 4x4x matrix inverse, multiplications. In some heavy rigs matrix inverse can be 10% of computation time. This reduces it to 2% by using Eigen's optimized 4x4 matrix inverse and SSE matrix multiplication. 2018-05-31 16:36:20 +02:00			`intern/matrix.cc`

CMake: prepare for BLENDER_SORTED_LIBS removal No functional change, this adds LIB definition and args to cmake files. Without this it's difficult to migrate away from 'BLENDER_SORTED_LIBS' since there are many platforms/configurations that could break when changing linking order. Manually add and enable WITHOUT_SORTED_LIBS to try building without sorted libs (currently fails since all variables are empty). This check will eventually be removed. See T46725. 2019-04-14 15:18:44 +02:00			`set(LIB`
Refactor: Build: Add bf::dependencies::eigen target To make adding a dependeny on TBB easier. Additional changes: * Using LIB for libmv tests, as it now brings in includes * Removing Eigen header listing in iTaSC Pull Request: https://projects.blender.org/blender/blender/pulls/136865 2025-04-02 02:59:02 +02:00			`PRIVATE bf::dependencies::eigen`
