From e9d1889891ce32ffb3d6425f1e70510ea2c3e24b Mon Sep 17 00:00:00 2001 From: "H. Verbeet" Date: Mon, 16 Jun 2008 10:40:32 -0600 Subject: Compute/setup fog coordinates even if vertex program is enabled. Only when fog's enabled, of course. In the usual case, this is just a pass-through operation. --- src/mesa/tnl/t_vb_fog.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'src/mesa/tnl/t_vb_fog.c') diff --git a/src/mesa/tnl/t_vb_fog.c b/src/mesa/tnl/t_vb_fog.c index d8bca3820bc..99e5a09c755 100644 --- a/src/mesa/tnl/t_vb_fog.c +++ b/src/mesa/tnl/t_vb_fog.c @@ -148,11 +148,11 @@ run_fog_stage(GLcontext *ctx, struct tnl_pipeline_stage *stage) struct fog_stage_data *store = FOG_STAGE_DATA(stage); GLvector4f *input; - if (!ctx->Fog.Enabled || ctx->VertexProgram._Current) - return GL_TRUE; + if (!ctx->Fog.Enabled) + return GL_TRUE; - if (ctx->Fog.FogCoordinateSource == GL_FRAGMENT_DEPTH_EXT) { + if (ctx->Fog.FogCoordinateSource == GL_FRAGMENT_DEPTH_EXT && !ctx->VertexProgram._Current) { GLuint i; GLfloat *coord; /* Fog is computed from vertex or fragment Z values */ -- cgit v1.2.3
