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/blend.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/mesa/main/blend.c') diff --git a/src/mesa/main/blend.c b/src/mesa/main/blend.c index 830e3b2e51..5a9d94e12d 100644 --- a/src/mesa/main/blend.c +++ b/src/mesa/main/blend.c @@ -564,7 +564,7 @@ void _mesa_init_color( GLcontext * ctx ) ctx->Color.AlphaEnabled = GL_FALSE; ctx->Color.AlphaFunc = GL_ALWAYS; ctx->Color.AlphaRef = 0; - ctx->Color.BlendEnabled = GL_FALSE; + ctx->Color.BlendEnabled = 0x0; ctx->Color.BlendSrcRGB = GL_ONE; ctx->Color.BlendDstRGB = GL_ZERO; ctx->Color.BlendSrcA = GL_ONE; -- cgit v1.2.3
