From eb522af4fec58876ac1b0a73ad9bcdae2d82d33f Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Sybren=20A=2E=20St=C3=BCvel?= Date: Fri, 6 Mar 2020 16:19:35 +0100 Subject: Cleanup: move Alembic, AVI, Collada, and USD to `source/blender/io` This moves the `alembic`, `avi`, `collada`, and `usd` modules into a common `io` directory. This also cleans up some `#include "../../{somedir}/{somefile}.h"` by adding `../../io/{somedir}` to `CMakeLists.txt` and then just using `#include "{somefile}.h"`. No functional changes. --- source/blender/io/collada/TransformReader.cpp | 151 ++++++++++++++++++++++++++ 1 file changed, 151 insertions(+) create mode 100644 source/blender/io/collada/TransformReader.cpp (limited to 'source/blender/io/collada/TransformReader.cpp') diff --git a/source/blender/io/collada/TransformReader.cpp b/source/blender/io/collada/TransformReader.cpp new file mode 100644 index 00000000000..8ee31f80405 --- /dev/null +++ b/source/blender/io/collada/TransformReader.cpp @@ -0,0 +1,151 @@ +/* + * This program is free software; you can redistribute it and/or + * modify it under the terms of the GNU General Public License + * as published by the Free Software Foundation; either version 2 + * of the License, or (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
