From 423f45d18a665423e319dcea08c11ff9f5646a80 Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Mon, 29 Jun 2009 15:24:42 -0600 Subject: [PATCH] gallium/draw: sketch out some missing pointcoord code The gl_PointCoord attribute is currently expected to be in the fog coord register's z/w components. This was never totally fleshed out though. This is just some placeholder code. --- src/gallium/auxiliary/draw/draw_pipe_wide_point.c | 12 +++++++++++- 1 file changed, 11 insertions(+), 1 deletion(-) diff --git a/src/gallium/auxiliary/draw/draw_pipe_wide_point.c b/src/gallium/auxiliary/draw/draw_pipe_wide_point.c index d84bab9eaae..014d8c7346d 100644 --- a/src/gallium/auxiliary/draw/draw_pipe_wide_point.c +++ b/src/gallium/auxiliary/draw/draw_pipe_wide_point.c @@ -181,6 +181,16 @@ static void widepoint_point( struct draw_stage *stage, } +static int +find_fog_input_attrib(struct draw_context *draw) +{ + /* Scan the fragment program's input decls to find the fogcoord + * attribute.
