From c0b4fb06b8b570b1999a0849797d3cb77f6ee5cd Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Thu, 31 Dec 2009 14:44:40 -0700 Subject: [PATCH 1/4] gallium: pipe_context::render_condition() and mode flags For conditional rendering predicated on results of an occlusion query. If this driver function is NULL, conditional rendering is not supported by the driver. --- src/gallium/include/pipe/p_context.h | 8 ++++++++ src/gallium/include/pipe/p_defines.h | 9 +++++++++ 2 files changed, 17 insertions(+), 0 deletions(-) diff --git a/src/gallium/include/pipe/p_context.h b/src/gallium/include/pipe/p_context.h index 6c06fb9..60fa9ce 100644 --- a/src/gallium/include/pipe/p_context.h +++ b/src/gallium/include/pipe/p_context.h @@ -84,6 +84,14 @@ struct pipe_context { unsigned count); /*@}*/ + /** + * Predicate subsequent rendering on occlusion query result + * \param query the query predicate, or NULL if no predicate + * \param mode one of PIPE_COND_RENDER_x + */ + void (*render_condition)( struct pipe_context *pipe, + struct pipe_query *query, + uint mode ); /** * Query objects diff --git a/src/gallium/include/pipe/p_defines.h b/src/gallium/include/pipe/p_defines.h index 2cda408..c3b1e63 100644 --- a/src/gallium/include/pipe/p_defines.h +++ b/src/gallium/include/pipe/p_defines.h @@ -355,6 +355,15 @@ enum pipe_transfer_usage { /** + * Conditional rendering modes + */ +#define PIPE_RENDER_COND_WAIT 0 +#define PIPE_RENDER_COND_NO_WAIT 1 +#define PIPE_RENDER_COND_BY_REGION_WAIT 2 +#define PIPE_RENDER_COND_BY_REGION_NO_WAIT 3 + + +/** * Point sprite coord modes */ #define PIPE_SPRITE_COORD_NONE 0 -- 1.6.2.5
