From 1dd737759639c63d3279be774202585de778dac5 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Cl=C3=A9ment=20Foucault?= Date: Fri, 7 Aug 2020 17:00:28 +0200 Subject: GPUBackend: Add new GPUBackend object to manage GL object allocations This just set a global object responsible for allocating new objects in a thread safe way without needing any GPUContext bound to this thread. This also introduce the GLContext which will contain all the GL related functions for the current context. --- source/blender/gpu/intern/gpu_backend.hh | 37 ++++++++++++++++++++++++++++++++ 1 file changed, 37 insertions(+) create mode 100644 source/blender/gpu/intern/gpu_backend.hh (limited to 'source/blender/gpu/intern/gpu_backend.hh') diff --git a/source/blender/gpu/intern/gpu_backend.hh b/source/blender/gpu/intern/gpu_backend.hh new file mode 100644 index 00000000000..24f592f214f --- /dev/null +++ b/source/blender/gpu/intern/gpu_backend.hh @@ -0,0 +1,37 @@ +/* + * 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.
