From 23caf20169ac38436ee9c13914f1d6aa7cf6bb5e Mon Sep 17 00:00:00 2001 From: Keith Whitwell Date: Thu, 16 Nov 2000 21:05:34 +0000 Subject: Move the transform and lighting code to two new directories math: Provides basic matrix and vector functionality that might be useful to multiple software t&l implementations, and is used by core mesa to manage the Model, Project, etc matrices. tnl: The real transform & lighting code from core mesa, including everything from glVertex3f through vertex buffer handling, transformation, clipping, lighting and handoff to a driver for rasterization. The interfaces of these can be further tightened up, but the basic splitting up of state and code move is done. --- src/mesa/math/m_translate.h | 92 +++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 92 insertions(+) create mode 100644 src/mesa/math/m_translate.h (limited to 'src/mesa/math/m_translate.h') diff --git a/src/mesa/math/m_translate.h b/src/mesa/math/m_translate.h new file mode 100644 index 0000000000..5c60b972ff --- /dev/null +++ b/src/mesa/math/m_translate.h @@ -0,0 +1,92 @@ +/* $Id: m_translate.h,v 1.1 2000/11/16 21:05:41 keithw Exp $ */ + +/* + * Mesa 3-D graphics library + * Version: 3.1 + * + * Copyright (C) 1999 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.
