From ea5fe7abc183c1e53d327f97280f589499fe60bb Mon Sep 17 00:00:00 2001 From: Campbell Barton Date: Tue, 7 Jul 2020 17:29:17 +1000 Subject: UV: path selection support This adds support for path selection for vertex edge & face selection modes, matching mesh editing behavior, useful with the UV rip tool. Region select & edge tagging are currently not supported, although they could be added eventually. --- source/blender/bmesh/tools/bmesh_path_uv.h | 47 ++++++++++++++++++++++++++++++ 1 file changed, 47 insertions(+) create mode 100644 source/blender/bmesh/tools/bmesh_path_uv.h (limited to 'source/blender/bmesh/tools/bmesh_path_uv.h') diff --git a/source/blender/bmesh/tools/bmesh_path_uv.h b/source/blender/bmesh/tools/bmesh_path_uv.h new file mode 100644 index 00000000000..c7c5768f7d0 --- /dev/null +++ b/source/blender/bmesh/tools/bmesh_path_uv.h @@ -0,0 +1,47 @@ +/* + * 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.
