From 13261304a331b4cff37de477ddf19c915ed64b2c Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Cl=C3=A9ment=20Foucault?= Date: Mon, 26 Feb 2018 19:41:17 +0100 Subject: DRW: Add new Draw Manager OpenGL Context. This separate context allows two things: - It allows viewports in multi-windows configuration. - F12 render can use this context in a separate thread and do a non-blocking render. The downside is that the context cannot be used while rendering so a request to refresh a viewport will lock the UI. This is something that will be adressed in the future. Under the hood what does that mean: - Not adding more mess with VAOs management in gawain. - Doing depth only draw for operators / selection needs to be done in an offscreen buffer. - The 3D cursor "autodis" operator is still reading the backbuffer so we need to copy the result to it. - All FBOs needed by the drawmanager must to be created/destroyed with its context active. - We cannot use batches created for UI in the DRW context and vice-versa. There is a clear separation of resources that enables the use of safe multi-threading. --- source/blender/gpu/GPU_batch.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'source/blender/gpu/GPU_batch.h') diff --git a/source/blender/gpu/GPU_batch.h b/source/blender/gpu/GPU_batch.h index d2f3409dc07..5807af7b359 100644 --- a/source/blender/gpu/GPU_batch.h +++ b/source/blender/gpu/GPU_batch.h @@ -58,6 +58,8 @@ void gpu_batch_init(void); void gpu_batch_exit(void); /* gpu_batch_presets.c */ +/* Only use by draw manager.
