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 new file mode 100644 index 000000000..3b8af930c --- /dev/null +++ b/nx-X11/extras/Mesa/src/mesa/swrast_setup/descrip.mms @@ -0,0 +1,39 @@ +# 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_context.c b/nx-X11/extras/Mesa/src/mesa/swrast_setup/ss_context.c new file mode 100644 index 000000000..c63646ca9 --- /dev/null +++ b/nx-X11/extras/Mesa/src/mesa/swrast_setup/ss_context.c @@ -0,0 +1,250 @@ +/* + * Mesa 3-D graphics library + * Version: 6.1 + * + * Copyright (C) 1999-2004 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.
