From d475730357ff1595470fbe9856b2c88ad0a771ca Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Fri, 20 Oct 2000 19:54:49 +0000 Subject: [PATCH] Changes for multitexture > 3, code clean-ups. Added GLboolean ctx->Texture.MultiTextureEnabled to determine when multitexture is enabled. Eventually ctx->Texture.ReallyEnabled may become a boolean. --- src/mesa/main/context.c | 12 +++++++++--- src/mesa/main/lines.c | 6 +++--- src/mesa/main/points.c | 10 +++++----- src/mesa/main/state.c | 7 ++++++- src/mesa/main/varray.c | 18 ++++++++++++++++-- 5 files changed, 39 insertions(+), 14 deletions(-) diff --git a/src/mesa/main/context.c b/src/mesa/main/context.c index 34180a78c23..3f4bcec2fb5 100644 --- a/src/mesa/main/context.c +++ b/src/mesa/main/context.c @@ -1,4 +1,4 @@ -/* $Id: context.c,v 1.92 2000/10/09 22:42:40 brianp Exp $ */ +/* $Id: context.c,v 1.93 2000/10/20 19:54:49 brianp Exp $ */ /* * Mesa 3-D graphics library @@ -882,8 +882,14 @@ init_attrib_groups( GLcontext *ctx ) ASSIGN_3V( ctx->Current.Normal, 0.0, 0.0, 1.0 ); ctx->Current.Primitive = (GLenum) (GL_POLYGON + 1); - ctx->Current.Flag = (VERT_NORM|VERT_INDEX|VERT_RGBA|VERT_EDGE| - VERT_TEX0_1|VERT_TEX1_1|VERT_MATERIAL); + ctx->Current.Flag = (VERT_NORM | + VERT_INDEX | + VERT_RGBA | + VERT_EDGE | + VERT_TEX0_1 | + VERT_TEX1_1 | + VERT_TEX2_1 | /* XXX fix for MAX_TEXTURE_UNITS > 3 */ + VERT_MATERIAL); init_fallback_arrays( ctx ); diff --git a/src/mesa/main/lines.c b/src/mesa/main/lines.c index 7330ea573bd..41d3262eadf 100644 --- a/src/mesa/main/lines.c +++ b/src/mesa/main/lines.c @@ -1,4 +1,4 @@ -/* $Id: lines.c,v 1.15 2000/09/30 18:42:29 brianp Exp $ */ +/* $Id: lines.c,v 1.16 2000/10/20 19:54:49 brianp Exp $ */ /* * Mesa 3-D graphics library @@ -1086,7 +1086,7 @@ void gl_set_line_function( GLcontext *ctx ) /* antialiased lines */ if (rgbmode) { if (ctx->Texture.ReallyEnabled) { - if (ctx->Texture.ReallyEnabled >= TEXTURE1_1D + if (ctx->Texture.MultiTextureEnabled || ctx->Light.Model.ColorControl==GL_SEPARATE_SPECULAR_COLOR) /* Multitextured!
