From f1b42595d02828bcc617bc88b4ce6cf38a69ddbf Mon Sep 17 00:00:00 2001 From: Brian Date: Mon, 17 Mar 2008 15:38:14 -0600 Subject: gallium: new mipmap generation code Based on code from Mesa's state tracker. Still need to implement fallbacks for those texture formats which can't generally be rendered to. --- src/gallium/auxiliary/util/u_gen_mipmap.h | 63 +++++++++++++++++++++++++++++++ 1 file changed, 63 insertions(+) create mode 100644 src/gallium/auxiliary/util/u_gen_mipmap.h (limited to 'src/gallium/auxiliary/util/u_gen_mipmap.h') diff --git a/src/gallium/auxiliary/util/u_gen_mipmap.h b/src/gallium/auxiliary/util/u_gen_mipmap.h new file mode 100644 index 0000000000..6ee909f0a6 --- /dev/null +++ b/src/gallium/auxiliary/util/u_gen_mipmap.h @@ -0,0 +1,63 @@ +/************************************************************************** + * + * Copyright 2008 Tungsten Graphics, Inc., Cedar Park, Texas. + * All Rights Reserved. + * + * Permission is hereby granted, free of charge, to any person obtaining a + * copy of this software and associated documentation files (the + * "Software"), to deal in the Software without restriction, including + * without limitation the rights to use, copy, modify, merge, publish, + * distribute, sub license, and/or sell copies of the Software, and to + * permit persons to whom the Software is furnished to do so, subject to + * the following conditions: + * + * The above copyright notice and this permission notice (including the + * next paragraph) shall be included in all copies or substantial portions + * of the Software. + * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS + * OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF + * MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NON-INFRINGEMENT. + * IN NO EVENT SHALL TUNGSTEN GRAPHICS AND/OR ITS SUPPLIERS BE LIABLE FOR + * ANY CLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT, + * TORT OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION WITH THE + * SOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE. + * + **************************************************************************/ + +#ifndef U_GENMIPMAP_H +#define U_GENMIPMAP_H + +#include "pipe/p_state.h" + + +struct gen_mipmap_state +{ + struct pipe_context *pipe; + + void *blend; + void *depthstencil; + void *rasterizer; + /*struct pipe_viewport_state viewport;*/ + struct pipe_sampler_state *vs; + struct pipe_sampler_state *fs; +}; + + + +extern struct gen_mipmap_state * +util_create_gen_mipmap(struct pipe_context *pipe); + + +extern void +util_destroy_gen_mipmap(struct gen_mipmap_state *ctx); + + + +extern void +util_gen_mipmap(struct gen_mipmap_state *ctx, + struct pipe_texture *pt, + uint face, uint baseLevel, uint lastLevel); + + +#endif -- cgit v1.2.3
