The main task of this module is to build -swrast vertices from the t&l vertex_buffer structs, and to use them to -perform triangle setup functions not implemented in the software -rasterizer. - -The module implements a full set of functions to plug into the -t_vb_render.c driver interface (tnl->Driver.Render.*). - -There are strong advantages to decoupling the software rasterizer from -the t&l module, primarily allowing hardware drivers better control -over fallbacks, the removal of implicit knowledge about the software -rasterizer in the t&l module, allowing the two modules to evolve -independently and allowing either to be substituted with equivalent -functionality from another codebase. - -This module implements triangle/quad setup for offset, unfilled and -twoside-lit triangles. The software rasterizer doesn't handle these -primitives directly. - -Hardware rasterization drivers typically use this module in situations -where no hardware rasterization is possible, ie during total -fallbacks. - -STATE - -To create and destroy the module: - - GLboolean _swsetup_CreateContext( GLcontext *ctx ); - void _swsetup_DestroyContext( GLcontext *ctx ); - -The module is not active by default, and must be installed by calling -_swrast_Wakeup(). This function installs internal swrast_setup -functions into all the tnl->Driver.Render driver hooks, thus taking -over the task of rasterization entirely: - - void _swrast_Wakeup( GLcontext *ctx ); - - -This module tracks state changes internally and maintains derived -values based on the current state. For this to work, the driver -ensure the following funciton is called whenever the state changes and -the swsetup module is 'awake': - - void _swsetup_InvalidateState( GLcontext *ctx, GLuint new_state ); - -There is no explicit call to put the swsetup module to sleep. Simply -install other function pointers into all the tnl->Driver.Render.* -hooks, and (optionally) cease calling _swsetup_InvalidateState(). - -DRIVER INTERFACE - -The module offers a minimal driver interface: - - void (*Start)( GLcontext *ctx ); - void (*Finish)( GLcontext *ctx ); - -These are called before and after the completion of all swrast drawing -activity. As swrast doesn't call callbacks during triangle, line or -point rasterization, these are necessary to provide locking hooks for -some drivers. They may otherwise be left null. - - diff --git a/nx-X11/extras/Mesa/src/mesa/swrast_setup/descrip.mms b/nx-X11/extras/Mesa/src/mesa/swrast_setup/descrip.mms deleted file mode 100644 index 3b8af930c..000000000 --- a/nx-X11/extras/Mesa/src/mesa/swrast_setup/descrip.mms +++ /dev/null @@ -1,39 +0,0 @@ -# Makefile for core library for VMS -# contributed by Jouk Jansen joukj@hrem.stm.tudelft.nl -# Last revision : 16 June 2003 - -.first - define gl [---.include.gl] - define math [-.math] - define tnl [-.tnl] - define swrast [-.swrast] - define array_cache [-.array_cache] - -.include [---]mms-config. - -##### MACROS ##### - -VPATH = RCS - -INCDIR = [---.include],[-.main],[-.glapi] -LIBDIR = [---.lib] -CFLAGS = /include=($(INCDIR),[])/define=(PTHREADS=1)/name=(as_is,short) - -SOURCES = ss_context.c ss_triangle.c - -OBJECTS = ss_context.obj,ss_triangle.obj -##### RULES ##### - -VERSION=Mesa V3.4 - -##### TARGETS ##### -# Make the library -$(LIBDIR)$(GL_LIB) : $(OBJECTS) - @ library $(LIBDIR)$(GL_LIB) $(OBJECTS) - -clean : - purge - delete *.obj;* - -ss_context.obj : ss_context.c -ss_triangle.obj : ss_triangle.c diff --git a/nx-X11/extras/Mesa/src/mesa/swrast_setup/ss_vb.h b/nx-X11/extras/Mesa/src/mesa/swrast_setup/ss_vb.h deleted file mode 100644 index 6ea0cb1a7..000000000 --- a/nx-X11/extras/Mesa/src/mesa/swrast_setup/ss_vb.h +++ /dev/null @@ -1,38 +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.
