From: Zack Rusin Date: Wed, 9 Jun 2010 15:13:34 +0000 (-0400) Subject: geometry shaders: make gs work with changable primitives and variable number of vertices X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d4ef0f6c67aefe06d8dd647acf8d9005df39a709;p=mesa.git geometry shaders: make gs work with changable primitives and variable number of vertices lots and lots of fixes for geometry shaders. in particular now we work when the gs emits a different primitive than the one the pipeline was started with and also we work when gs emits more vertices than would fit in the original buffer. --- diff --git a/src/gallium/auxiliary/draw/draw_gs.c b/src/gallium/auxiliary/draw/draw_gs.c index 131deed43e4..4034bd40bbe 100644 --- a/src/gallium/auxiliary/draw/draw_gs.c +++ b/src/gallium/auxiliary/draw/draw_gs.c @@ -112,7 +112,7 @@ draw_create_geometry_shader(struct draw_context *draw, TGSI_PROPERTY_GS_OUTPUT_PRIM) gs->output_primitive = gs->info.properties[i].data[0];
