From d294f79190a5b25ef0fbbbf3ac94b15c9402d009 Mon Sep 17 00:00:00 2001 From: Roland Scheidegger Date: Wed, 3 Nov 2004 17:29:39 +0000 Subject: [PATCH] enable GL_EXT_fog_coord. Calculate fog factors and submit them instead of fog coords (it seems the chip cannot do fog factor computation when not using fragment depth as fog coord source). vtxfmt uses fallback for now (most code present but some magic would be needed if replaying vertices is necessary later on). --- src/mesa/drivers/dri/r200/r200_context.c | 4 + src/mesa/drivers/dri/r200/r200_context.h | 5 + src/mesa/drivers/dri/r200/r200_maos_arrays.c | 56 ++++++++++++ src/mesa/drivers/dri/r200/r200_state.c | 33 ++++++- src/mesa/drivers/dri/r200/r200_swtcl.c | 7 +- src/mesa/drivers/dri/r200/r200_tcl.c | 96 ++++++++++++++++++++ src/mesa/drivers/dri/r200/r200_tcl.h | 4 + src/mesa/drivers/dri/r200/r200_vtxfmt.c | 37 +++++++- src/mesa/drivers/dri/r200/r200_vtxfmt_c.c | 33 ++++++- 9 files changed, 266 insertions(+), 9 deletions(-) diff --git a/src/mesa/drivers/dri/r200/r200_context.c b/src/mesa/drivers/dri/r200/r200_context.c index 0868febc346..d5d2ce150a5 100644 --- a/src/mesa/drivers/dri/r200/r200_context.c +++ b/src/mesa/drivers/dri/r200/r200_context.c @@ -131,6 +131,7 @@ static const char * const card_extensions[] = "GL_ARB_vertex_buffer_object", "GL_EXT_blend_minmax", "GL_EXT_blend_subtract", + "GL_EXT_fog_coord", "GL_EXT_secondary_color", "GL_EXT_stencil_wrap", "GL_EXT_texture_edge_clamp", @@ -252,6 +253,9 @@ GLboolean r200CreateContext( const __GLcontextModes *glVisual, rmesa = (r200ContextPtr) CALLOC( sizeof(*rmesa) );
