From fd5511d27fc44096117c47ab503fb5b47f993061 Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Tue, 29 Dec 2009 16:17:14 -0700 Subject: mesa: implement per-buffer color masking This is part of the GL_EXT_draw_buffers2 extension and part of GL 3.0. The ctx->Color.ColorMask field is now a 2-D array. Until drivers are modified to support per-buffer color masking, they can just look at the 0th color mask. The new _mesa_ColorMaskIndexed() function will be called by glColorMaskIndexedEXT() or glColorMaski(). --- src/mesa/drivers/common/driverfuncs.c | 22 +++++++++++++++++----- 1 file changed, 17 insertions(+), 5 deletions(-) (limited to 'src/mesa/drivers/common/driverfuncs.c') diff --git a/src/mesa/drivers/common/driverfuncs.c b/src/mesa/drivers/common/driverfuncs.c index 9b271f85e92..5c5e17820d6 100644 --- a/src/mesa/drivers/common/driverfuncs.c +++ b/src/mesa/drivers/common/driverfuncs.c @@ -264,11 +264,23 @@ _mesa_init_driver_state(GLcontext *ctx) ctx->Color.BlendDstRGB, ctx->Color.BlendSrcA, ctx->Color.BlendDstA); - ctx->Driver.ColorMask(ctx, - ctx->Color.ColorMask[RCOMP], - ctx->Color.ColorMask[GCOMP], - ctx->Color.ColorMask[BCOMP], - ctx->Color.ColorMask[ACOMP]); + if (ctx->Driver.ColorMaskIndexed) { + GLuint i; + for (i = 0; i < ctx->Const.MaxDrawBuffers; i++) { + ctx->Driver.ColorMaskIndexed(ctx, i, + ctx->Color.ColorMask[0][RCOMP], + ctx->Color.ColorMask[0][GCOMP], + ctx->Color.ColorMask[0][BCOMP], + ctx->Color.ColorMask[0][ACOMP]); + } + } + else { + ctx->Driver.ColorMask(ctx, + ctx->Color.ColorMask[0][RCOMP], + ctx->Color.ColorMask[0][GCOMP], + ctx->Color.ColorMask[0][BCOMP], + ctx->Color.ColorMask[0][ACOMP]); + } ctx->Driver.CullFace(ctx, ctx->Polygon.CullFaceMode); ctx->Driver.DepthFunc(ctx, ctx->Depth.Func); -- cgit v1.2.3
