From 0bd1cbcd0d28dbadfb0c3e1f8b048a18b56bc72c Mon Sep 17 00:00:00 2001 From: Keith Whitwell Date: Fri, 14 May 2010 13:04:42 +0100 Subject: gallium: convert rasterizer state to use gl-style front/back concepts Use front/back instead of cw/ccw throughout. Also, use offset_point/line/fill instead of offset_cw/ccw. Brings gallium representation of this state into line with its main user, and also what turns out to be the most common hardware representation. This fixes a long-standing bias in the interface towards the architecture of the software rasterizer. --- src/gallium/drivers/llvmpipe/lp_setup_tri.c | 10 +++++----- src/gallium/drivers/llvmpipe/lp_state_rasterizer.c | 4 ++-- 2 files changed, 7 insertions(+), 7 deletions(-) (limited to 'src/gallium/drivers/llvmpipe') diff --git a/src/gallium/drivers/llvmpipe/lp_setup_tri.c b/src/gallium/drivers/llvmpipe/lp_setup_tri.c index 53b91690b68..fbbfa3275f3 100644 --- a/src/gallium/drivers/llvmpipe/lp_setup_tri.c +++ b/src/gallium/drivers/llvmpipe/lp_setup_tri.c @@ -671,14 +671,14 @@ void lp_setup_choose_triangle( struct lp_setup_context *setup ) { switch (setup->cullmode) { - case PIPE_WINDING_NONE: + case PIPE_FACE_NONE: setup->triangle = triangle_both; break; - case PIPE_WINDING_CCW: - setup->triangle = triangle_cw; + case PIPE_FACE_FRONT: + setup->triangle = setup->ccw_is_frontface ? triangle_ccw : triangle_cw; break; - case PIPE_WINDING_CW: - setup->triangle = triangle_ccw; + case PIPE_FACE_BACK: + setup->triangle = setup->ccw_is_frontface ? triangle_cw : triangle_ccw; break; default: setup->triangle = triangle_nop; diff --git a/src/gallium/drivers/llvmpipe/lp_state_rasterizer.c b/src/gallium/drivers/llvmpipe/lp_state_rasterizer.c index 622eb47ff45..afd3e0b21c9 100644 --- a/src/gallium/drivers/llvmpipe/lp_state_rasterizer.c +++ b/src/gallium/drivers/llvmpipe/lp_state_rasterizer.c @@ -67,8 +67,8 @@ llvmpipe_bind_rasterizer_state(struct pipe_context *pipe, void *handle) */ if (llvmpipe->rasterizer) { lp_setup_set_triangle_state( llvmpipe->setup, - llvmpipe->rasterizer->cull_mode, - llvmpipe->rasterizer->front_winding == PIPE_WINDING_CCW, + llvmpipe->rasterizer->cull_face, + llvmpipe->rasterizer->front_ccw, llvmpipe->rasterizer->scissor, llvmpipe->rasterizer->gl_rasterization_rules); lp_setup_set_flatshade_first( llvmpipe->setup, -- cgit v1.2.3
