From 3b71cb6ad6dabfefc9363a35872f4e70e1125603 Mon Sep 17 00:00:00 2001 From: Chia-I Wu Date: Sat, 27 Nov 2010 15:04:30 +0800 Subject: [PATCH] st/vega: Add POLYGON_STENCIL and POLYGON_FILL renderer state. The states are designated for polygon filling. Polygon filling is a two-pass process utilizing the stencil buffer. polygon_fill and polygon_array_fill functions are updated to make use of the state. --- src/gallium/state_trackers/vega/polygon.c | 300 +++++---------------- src/gallium/state_trackers/vega/renderer.c | 195 ++++++++++++++ src/gallium/state_trackers/vega/renderer.h | 22 ++ 3 files changed, 277 insertions(+), 240 deletions(-) diff --git a/src/gallium/state_trackers/vega/polygon.c b/src/gallium/state_trackers/vega/polygon.c index ca8831064c9..a491de27fa6 100644 --- a/src/gallium/state_trackers/vega/polygon.c +++ b/src/gallium/state_trackers/vega/polygon.c @@ -244,24 +244,11 @@ VGboolean polygon_is_closed(struct polygon *p) return floatsEqual(start[0], end[0]) && floatsEqual(start[1], end[1]); } -static void set_blend_for_fill(struct pipe_blend_state *blend) -{ - memset(blend, 0, sizeof(struct pipe_blend_state)); - blend->rt[0].colormask = 0; /*disable colorwrites*/ - - blend->rt[0].rgb_src_factor = PIPE_BLENDFACTOR_ONE; - blend->rt[0].alpha_src_factor = PIPE_BLENDFACTOR_ONE; - blend->rt[0].rgb_dst_factor = PIPE_BLENDFACTOR_INV_SRC_ALPHA; - blend->rt[0].alpha_dst_factor = PIPE_BLENDFACTOR_INV_SRC_ALPHA; -} - -static void draw_polygon(struct vg_context *ctx, - struct polygon *poly) +static void polygon_prepare_buffer(struct vg_context *ctx, + struct polygon *poly) { int vert_size; struct pipe_context *pipe; - struct pipe_vertex_buffer vbuffer; - struct pipe_vertex_element velement; vert_size = poly->num_verts * COMPONENTS * sizeof(float); @@ -281,35 +268,15 @@ static void draw_polygon(struct vg_context *ctx, PIPE_BIND_VERTEX_BUFFER); poly->dirty = VG_FALSE; } - - - /* tell pipe about the vertex buffer */ - memset(&vbuffer, 0, sizeof(vbuffer)); - vbuffer.buffer = poly->vbuf; - vbuffer.stride = COMPONENTS * sizeof(float); /* vertex size */ - vbuffer.buffer_offset = 0; - vbuffer.max_index = poly->num_verts - 1; - pipe->set_vertex_buffers(pipe, 1, &vbuffer); - - /* tell pipe about the vertex attributes */ - memset(&velement, 0, sizeof(velement)); - velement.src_offset = 0; - velement.instance_divisor = 0; - velement.vertex_buffer_index = 0; - velement.src_format = PIPE_FORMAT_R32G32_FLOAT; - cso_set_vertex_elements(ctx->cso_context, 1, &velement); - - /* draw */ - util_draw_arrays(pipe, PIPE_PRIM_TRIANGLE_FAN, 0, (uint) poly->num_verts); } void polygon_fill(struct polygon *poly, struct vg_context *ctx) { - struct pipe_depth_stencil_alpha_state dsa; - struct pipe_stencil_ref sr; - struct pipe_blend_state blend; + struct pipe_vertex_element velement; + struct pipe_vertex_buffer vbuffer; VGfloat bounds[4]; VGfloat min_x, min_y, max_x, max_y; + assert(poly); polygon_bounding_rect(poly, bounds); min_x = bounds[0]; @@ -322,113 +289,42 @@ void polygon_fill(struct polygon *poly, struct vg_context *ctx) min_x, min_y, max_x, max_y); #endif - set_blend_for_fill(&blend); - - memset(&dsa, 0, sizeof(struct pipe_depth_stencil_alpha_state)); - memset(&sr, 0, sizeof(struct pipe_stencil_ref)); - /* only need a fixed 0.
