An example is fog - * coordinate generation, which is not required in the FX driver. - * - * - replacing general-purpose machine-independent stages with - * general-purpose machine-specific stages. There is no example of - * this to date, though it must be borne in mind that all subsequent - * stages that reference the output of the new stage must cope with - * any machine-specific data introduced. This may not be easy - * unless there are no such stages (ie the new stage is the last in - * the pipe). - * - * - inserting optimized (but specialized) stages ahead of the - * general-purpose fallback implementation. For example, the old - * fastpath mechanism, which only works when the VB->Elts input is - * available, can be duplicated by placing the fastpath stage at the - * head of this pipeline. Such specialized stages are currently - * constrained to have no outputs (ie. they must either finish the * - * pipeline by returning GL_FALSE from run(), or do nothing). - * - * Some work can be done to lift some of the restrictions in the final - * case, if it becomes necessary to do so. - */ -const struct tnl_pipeline_stage *_tnl_default_pipeline[] = { - &_tnl_vertex_transform_stage, - &_tnl_normal_transform_stage, - &_tnl_lighting_stage, - &_tnl_fog_coordinate_stage, - &_tnl_texgen_stage, - &_tnl_texture_transform_stage, - &_tnl_point_attenuation_stage, -#if defined(FEATURE_NV_vertex_program) || defined(FEATURE_ARB_vertex_program) - &_tnl_arb_vertex_program_stage, - &_tnl_vertex_program_stage, -#endif - &_tnl_render_stage, - NULL -}; - -const struct tnl_pipeline_stage *_tnl_vp_pipeline[] = { - &_tnl_arb_vertex_program_stage, - &_tnl_render_stage, - NULL -}; diff --git a/nx-X11/extras/Mesa/src/mesa/tnl/t_pipeline.h b/nx-X11/extras/Mesa/src/mesa/tnl/t_pipeline.h deleted file mode 100644 index 6c7a0814c..000000000 --- a/nx-X11/extras/Mesa/src/mesa/tnl/t_pipeline.h +++ /dev/null @@ -1,76 +0,0 @@ - -/* - * Mesa 3-D graphics library - * Version: 3.5 - * - * Copyright (C) 1999-2001 Brian Paul 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, sublicense, - * 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 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 NONINFRINGEMENT.
