From 33a838beb913c011b5ee8158c2717b7c8c351b17 Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Mon, 10 Aug 2009 13:35:58 -0600 Subject: mesa: new driver meta-ops module Implement glClear() in terms of quad rendering, implement glBlitFramebuffer() in terms of glCopyTexImage2D + textured quad, etc. There have been several places in the drivers where we've implemented meta rendering similar to this. This is an effort to do it in a more portable and more efficient form. The _mesa_meta_begin/end() functions act like glPush/PopAttrib() but are lighter-weight. Plus, _mesa_meta_begin() resets GL state back to default values (texturing off, identity vertex transform, etc) so the meta drawing functions don't have to worry about it. For now only _mesa_mesa_blit_framebuffer() and _mesa_meta_clear() are implemented. glDrawPixels() and glCopyPixels() would be the next candidates. --- src/mesa/drivers/common/meta.c | 814 +++++++++++++++++++++++++++++++++++++++++ 1 file changed, 814 insertions(+) create mode 100644 src/mesa/drivers/common/meta.c (limited to 'src/mesa/drivers/common/meta.c') diff --git a/src/mesa/drivers/common/meta.c b/src/mesa/drivers/common/meta.c new file mode 100644 index 0000000000..8123a762d2 --- /dev/null +++ b/src/mesa/drivers/common/meta.c @@ -0,0 +1,814 @@ +/* + * Mesa 3-D graphics library + * Version: 7.6 + * + * Copyright (C) 2009 VMware, Inc.
