From 3728673bd1b974e54858fbab6ff62d3607b0d3f0 Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Tue, 29 Dec 2009 15:04:03 -0700 Subject: mesa: per-buffer blend enabled flags ctx->Color.BlendEnabled is now a GLbitfield instead of a GLboolean to indicate blend on/off status for each color/draw buffer. This is infrastructure for GL_EXT_draw_buffers2 and OpenGL 3.x New functions include _mesa_EnableIndexed(), _mesa_DisableIndexed(), and _mesa_IsEnabledIndexed(). The enable function corresponds to glEnableIndexedEXT() for GL_EXT_draw_buffers2 or glEnablei() for GL3. Note that there's quite a few tests for ctx->Color.BlendEnabled != 0 in drivers, etc. Those tests can remain as-is since the mask will be 0 or ~0 unless GL_EXT_draw_buffers2 is enabled. --- src/mesa/main/mtypes.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/mesa/main/mtypes.h') diff --git a/src/mesa/main/mtypes.h b/src/mesa/main/mtypes.h index b52c84b491..170c35b11c 100644 --- a/src/mesa/main/mtypes.h +++ b/src/mesa/main/mtypes.h @@ -581,7 +581,7 @@ struct gl_colorbuffer_attrib * \name Blending */ /*@{*/ - GLboolean BlendEnabled; /**< Blending enabled flag */ + GLbitfield BlendEnabled; /**< Per-buffer blend enable flags */ GLenum BlendSrcRGB; /**< Blending source operator */ GLenum BlendDstRGB; /**< Blending destination operator */ GLenum BlendSrcA; /**< GL_INGR_blend_func_separate */ -- cgit v1.2.3
