From 2d187672b7e38fcd8f6caa93f35dceb6fa11aa7f Mon Sep 17 00:00:00 2001 From: Brian Date: Thu, 30 Aug 2007 11:08:03 -0600 Subject: Sketch out per-vertex point size. The code is all in place, but mostly disabled for now: In t_vp_build.c, write the VERT_RESULT_PSIZE register In sp_state_derived.c, need to emit vertex point size if drawing points. In setup_point() use the point size from the vertex. --- src/mesa/pipe/softpipe/sp_state_derived.c | 6 ++++++ 1 file changed, 6 insertions(+) (limited to 'src/mesa/pipe/softpipe/sp_state_derived.c') diff --git a/src/mesa/pipe/softpipe/sp_state_derived.c b/src/mesa/pipe/softpipe/sp_state_derived.c index b0d79eedda..3bbe9c9fd9 100644 --- a/src/mesa/pipe/softpipe/sp_state_derived.c +++ b/src/mesa/pipe/softpipe/sp_state_derived.c @@ -102,6 +102,12 @@ static void calculate_vertex_layout( struct softpipe_context *softpipe ) emit_vertex_attr(vinfo, TGSI_ATTRIB_FOG, FORMAT_1F, INTERP_PERSPECTIVE); } + /* point size */ +#if 0 + /* XXX only emit if drawing points or front/back polygon mode is point mode */ + emit_vertex_attr(vinfo, TGSI_ATTRIB_POINTSIZE, FORMAT_4F, INTERP_CONSTANT); +#endif + /* texcoords and varying vars */ for (i = TGSI_ATTRIB_TEX0; i < TGSI_ATTRIB_VAR7; i++) { if (inputsRead & (1 << i)) { -- cgit v1.2.3
