From 20f7aaf6be0dc186f6551761693133bb562a5be1 Mon Sep 17 00:00:00 2001 From: Antony Riakiotakis Date: Tue, 6 May 2014 23:30:51 +0300 Subject: Fix issue discovered while investigating T39950: Sculpt mode drawing fails after deleting a subsurf modifier in sculpt mode and undoing. This was quite difficult to spot. Main cause was that mesh data was not synchronized properly between undo and sculpt code because we generated a pbvh on derivedmesh invalidation without really refreshing the rest of the data. This could result in undo and drawing operating on different data. To solve this and avoid bad level calls I had to move quite some code around. Crazyspace is now moved to blenkernel, as did some sculpt calls that make sure sculpt data are properly refreshed. --- source/blender/blenkernel/BKE_crazyspace.h | 54 +++ source/blender/blenkernel/BKE_paint.h | 11 + source/blender/blenkernel/CMakeLists.txt | 4 +- source/blender/blenkernel/intern/DerivedMesh.c | 3 +- source/blender/blenkernel/intern/crazyspace.c | 448 ++++++++++++++++++++ source/blender/blenkernel/intern/paint.c | 241 +++++++++++ source/blender/editors/include/ED_sculpt.h | 7 - source/blender/editors/include/ED_util.h | 8 - source/blender/editors/object/object_modifier.c | 2 +- source/blender/editors/sculpt_paint/sculpt.c | 231 +---------- .../blender/editors/sculpt_paint/sculpt_intern.h | 5 - .../editors/transform/transform_conversions.c | 2 +- source/blender/editors/util/CMakeLists.txt | 1 - source/blender/editors/util/crazyspace.c | 449 --------------------- 14 files changed, 762 insertions(+), 704 deletions(-) create mode 100644 source/blender/blenkernel/BKE_crazyspace.h create mode 100644 source/blender/blenkernel/intern/crazyspace.c delete mode 100644 source/blender/editors/util/crazyspace.c diff --git a/source/blender/blenkernel/BKE_crazyspace.h b/source/blender/blenkernel/BKE_crazyspace.h new file mode 100644 index 00000000000..89cbd9ec119 --- /dev/null +++ b/source/blender/blenkernel/BKE_crazyspace.h @@ -0,0 +1,54 @@ +/* + * ***** BEGIN GPL LICENSE BLOCK ***** + * + * 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.
