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.

Gawain: reorganize source code Put Gawain source code in a subfolder to make the boundary between the library and the rest of Blender clear. Changed Gawain’s license from Apache to Mozilla Public License. Has more essence of copyleft — closer to GPL but not as restrictive. Split immediate.c into several files so parts can be reused (adding more files soon…) 2016-09-13 02:18:33 -04:00
GWN: Perf: Bypass glUseProgram(0) I left a flag to quickly debug if something is wrong. But now that everything uses shader, it seems to be alright since a shader is always set active before drawing. 2018-03-30 23:27:45 +02:00			`#define PROGRAM_NO_OPTI 0`
Cleanup: Rename `#if GPU_USE_PY_REFERENCES` to `#ifndef GPU_NO_USE_PY_REFERENCES` This is safer for incremental build. And there was already a macro `GPU_USE_PY_REFERENCES` used elsewhere. 2021-04-30 11:20:39 -03:00			`//#define GPU_NO_USE_PY_REFERENCES`

Gawain: add method of stepping over data directly This avoids using GWN_vertbuf_attr_set which needs to calculate the offset and perform a memcpy every call. Exposing the data directly allows us to avoid a memcpy in some cases and means we can write to the vertex buffer's memory directly. 2017-06-29 20:09:05 +10:00
