From 8c7135ee14fb6f4d8b6e64d570daee3512c99438 Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Wed, 21 Jan 2009 09:05:02 -0700 Subject: [PATCH] swrast: fix redundant texture application in affine_textured_triangle(). This function does simple texture mapping so disable normal texture mapping before we call _swrast_write_rgba_span() so that we don't do it twice. --- src/mesa/swrast/s_triangle.c | 10 +++++++++- 1 file changed, 9 insertions(+), 1 deletion(-) diff --git a/src/mesa/swrast/s_triangle.c b/src/mesa/swrast/s_triangle.c index 2033ab55291..a2e8433e271 100644 --- a/src/mesa/swrast/s_triangle.c +++ b/src/mesa/swrast/s_triangle.c @@ -1,6 +1,6 @@ /* * Mesa 3-D graphics library - * Version: 6.5.3 + * Version: 7.3 * * Copyright (C) 1999-2007 Brian Paul All Rights Reserved. * @@ -263,6 +263,10 @@ affine_span(GLcontext *ctx, SWspan *span, struct affine_info *info) { GLchan sample[4]; /* the filtered texture sample */ + const GLuint texEnableSave = ctx->Texture._EnabledUnits; + + /* Disable tex units so they're not re-applied in swrast_write_rgba_span */ + ctx->Texture._EnabledUnits = 0x0; /* Instead of defining a function for each mode, a test is done * between the outer and inner loops.
