From 53560311294814ae0daa8457307a2b25077bf4e9 Mon Sep 17 00:00:00 2001 From: Keith Whitwell Date: Tue, 17 Jul 2001 19:39:32 +0000 Subject: Lighting now emits colors as CHAN_TYPE, as it used to. This will require minor adjustments in the dri drivers for twosided lighting to work again. --- src/mesa/drivers/common/t_dd_tritmp.h | 14 +-- src/mesa/swrast/s_context.c | 6 +- src/mesa/swrast_setup/ss_context.c | 18 ++- src/mesa/swrast_setup/ss_context.h | 8 +- src/mesa/swrast_setup/ss_triangle.c | 6 +- src/mesa/swrast_setup/ss_tritmp.h | 10 +- src/mesa/swrast_setup/ss_vb.c | 70 +++++++++-- src/mesa/swrast_setup/ss_vbtmp.h | 29 ++--- src/mesa/tnl/t_vb_light.c | 75 +++++++++--- src/mesa/tnl/t_vb_lighttmp.h | 217 ++++++++++++++++++++-------------- 10 files changed, 293 insertions(+), 160 deletions(-) diff --git a/src/mesa/drivers/common/t_dd_tritmp.h b/src/mesa/drivers/common/t_dd_tritmp.h index ce63e0c50d..9408588b5f 100644 --- a/src/mesa/drivers/common/t_dd_tritmp.h +++ b/src/mesa/drivers/common/t_dd_tritmp.h @@ -1,4 +1,4 @@ -/* $Id: t_dd_tritmp.h,v 1.11 2001/06/01 12:07:15 keithw Exp $ */ +/* $Id: t_dd_tritmp.h,v 1.12 2001/07/17 19:39:32 keithw Exp $ */ /* * Mesa 3-D graphics library @@ -177,9 +177,9 @@ static void TAG(triangle)( GLcontext *ctx, GLuint e0, GLuint e1, GLuint e2 ) } } else { - GLfloat (*vbcolor)[4] = VB->ColorPtr[1]->Ptr;
