3DFX GLIDE Source Code General Public License | |
1. PREAMBLE | |
This license is for software that provides a 3D graphics application | |
program interface (API).The license is intended to offer terms similar | |
to some standard General Public Licenses designed to foster open | |
standards and unrestricted accessibility to source code. Some of these | |
licenses require that, as a condition of the license of the software, | |
any derivative works (that is, new software which is a work containing | |
the original program or a portion of it) must be available for general | |
use, without restriction other than for a minor transfer fee, and that | |
the source code for such derivative works must likewise be made | |
available. The only restriction is that such derivative works must be | |
subject to the same General Public License terms as the original work. | |
This 3dfx GLIDE Source Code General Public License differs from the | |
standard licenses of this type in that it does not require the entire | |
derivative work to be made available under the terms of this license | |
nor is the recipient required to make available the source code for | |
the entire derivative work. Rather, the license is limited to only the | |
identifiable portion of the derivative work that is derived from the | |
licensed software. The precise terms and conditions for copying, | |
distribution and modification follow. | |
2. DEFINITIONS | |
2.1 This License applies to any program (or other "work") which | |
contains a notice placed by the copyright holder saying it may be | |
distributed under the terms of this 3dfx GLIDE Source Code General | |
Public License. | |
2.2 The term "Program" as used in this Agreement refers to 3DFX's | |
GLIDE source code and object code and any Derivative Work. | |
2.3 "Derivative Work" means, for the purpose of the License, that | |
portion of any work that contains the Program or the identifiable | |
portion of a work that is derived from the Program, either verbatim or | |
with modifications and/or translated into another language, and that | |
performs 3D graphics API operations. It does not include any other | |
portions of a work. | |
2.4 "Modifications of the Program" means any work, which includes a | |
Derivative Work, and includes the whole of such work. | |
2.5 "License" means this 3dfx GLIDE Source Code General Public License. | |
2.6 The "Source Code" for a work means the preferred form of the work | |
for making modifications to it. For an executable work, complete source | |
code means all the source code for all modules it contains, any | |
associated interface definition files, and the scripts used to control | |
compilation and installation of the executable work. | |
2.7 "3dfx" means 3dfx Interactive, Inc. | |
3. LICENSED ACTIVITIES | |
3.1 COPYING - You may copy and distribute verbatim copies of the | |
Program's Source Code as you receive it, in any medium, subject to the | |
provision of section 3.3 and provided also that: | |
(a) you conspicuously and appropriately publish on each copy | |
an appropriate copyright notice (3dfx Interactive, Inc. 1999), a notice | |
that recipients who wish to copy, distribute or modify the Program can | |
only do so subject to this License, and a disclaimer of warranty as | |
set forth in section 5; | |
(b) keep intact all the notices that refer to this License and | |
to the absence of any warranty; and | |
(c) do not make any use of the GLIDE trademark without the prior | |
written permission of 3dfx, and | |
(d) give all recipients of the Program a copy of this License | |
along with the Program or instructions on how to easily receive a copy | |
of this License. | |
3.2 MODIFICATION OF THE PROGRAM/DERIVATIVE WORKS - You may modify your | |
copy or copies of the Program or any portion of it, and copy and | |
distribute such modifications subject to the provisions of section 3.3 | |
and provided that you also meet all of the following conditions: | |
(a) you conspicuously and appropriately publish on each copy | |
of a Derivative Work an appropriate copyright notice, a notice that | |
recipients who wish to copy, distribute or modify the Derivative Work | |
can only do so subject to this License, and a disclaimer of warranty | |
as set forth in section 5; | |
(b) keep intact all the notices that refer to this License and | |
to the absence of any warranty; and | |
(c) give all recipients of the Derivative Work a copy of this | |
License along with the Derivative Work or instructions on how to easily | |
receive a copy of this License. | |
(d) You must cause the modified files of the Derivative Work | |
to carry prominent notices stating that you changed the files and the | |
date of any change. | |
(e) You must cause any Derivative Work that you distribute or | |
publish to be licensed at no charge to all third parties under the | |
terms of this License. | |
(f) You do not make any use of the GLIDE trademark without the | |
prior written permission of 3dfx. | |
(g) If the Derivative Work normally reads commands | |
interactively when run, you must cause it, when started running for | |
such interactive use, to print or display an announcement as follows: | |
"COPYRIGHT 3DFX INTERACTIVE, INC. 1999, ALL RIGHTS RESERVED THIS | |
SOFTWARE IS FREE AND PROVIDED "AS IS," WITHOUT WARRANTY OF ANY KIND, | |
EITHER EXPRESSED OR IMPLIED. THERE IS NO RIGHT TO USE THE GLIDE | |
TRADEMARK WITHOUT PRIOR WRITTEN PERMISSION OF 3DFX INTERACTIVE, | |
INC. SEE THE 3DFX GLIDE GENERAL PUBLIC LICENSE FOR A FULL TEXT OF THE | |
DISTRIBUTION AND NON-WARRANTY PROVISIONS (REQUEST COPY FROM | |
INFO@3DFX.COM)." | |
(h) The requirements of this section 3.2 do not apply to the | |
modified work as a whole but only to the Derivative Work. It is not | |
the intent of this License to claim rights or contest your rights to | |
work written entirely by you; rather, the intent is to exercise the | |
right to control the distribution of Derivative Works. | |
3.3 DISTRIBUTION | |
(a) All copies of the Program or Derivative Works which are | |
distributed must include in the file headers the following language | |
verbatim: | |
"THIS SOFTWARE IS SUBJECT TO COPYRIGHT PROTECTION AND IS OFFERED | |
ONLY PURSUANT TO THE 3DFX GLIDE GENERAL PUBLIC LICENSE. THERE IS NO | |
RIGHT TO USE THE GLIDE TRADEMARK WITHOUT PRIOR WRITTEN PERMISSION OF | |
3DFX INTERACTIVE, INC. A COPY OF THIS LICENSE MAY BE OBTAINED FROM | |
THE DISTRIBUTOR OR BY CONTACTING 3DFX INTERACTIVE INC (info@3dfx.com). | |
THIS PROGRAM. IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER | |
EXPRESSED OR IMPLIED. SEE THE 3DFX GLIDE GENERAL PUBLIC LICENSE FOR A | |
FULL TEXT OF THE NON-WARRANTY PROVISIONS. | |
USE, DUPLICATION OR DISCLOSURE BY THE GOVERNMENT IS SUBJECT TO | |
RESTRICTIONS AS SET FORTH IN SUBDIVISION (C)(1)(II) OF THE RIGHTS | |
IN TECHNICAL DATA AND COMPUTER SOFTWARE CLAUSE AT DFARS 252.227-7013, | |
AND/OR IN SIMILAR OR SUCCESSOR CLAUSES IN THE FAR, DOD OR NASA FAR | |
SUPPLEMENT. UNPUBLISHED RIGHTS RESERVED UNDER THE COPYRIGHT LAWS OF | |
THE UNITED STATES. | |
COPYRIGHT 3DFX INTERACTIVE, INC. 1999, ALL RIGHTS RESERVED" | |
(b) You may distribute the Program or a Derivative Work in | |
object code or executable form under the terms of Sections 3.1 and 3.2 | |
provided that you also do one of the following: | |
(1) Accompany it with the complete corresponding | |
machine-readable source code, which must be distributed under the | |
terms of Sections 3.1 and 3.2; or, | |
(2) Accompany it with a written offer, valid for at | |
least three years, to give any third party, for a charge no more than | |
your cost of physically performing source distribution, a complete | |
machine-readable copy of the corresponding source code, to be | |
distributed under the terms of Sections 3.1 and 3.2 on a medium | |
customarily used for software interchange; or, | |
(3) Accompany it with the information you received as | |
to the offer to distribute corresponding source code. (This alternative | |
is allowed only for noncommercial distribution and only if you received | |
the program in object code or executable form with such an offer, in | |
accord with Subsection 3.3(b)(2) above.) | |
(c) The source code distributed need not include anything | |
that is normally distributed (in either source or binary form) with | |
the major components (compiler, kernel, and so on) of the operating | |
system on which the executable runs, unless that component itself | |
accompanies the executable code. | |
(d) If distribution of executable code or object code is made | |
by offering access to copy from a designated place, then offering | |
equivalent access to copy the source code from the same place counts | |
as distribution of the source code, even though third parties are not | |
compelled to copy the source along with the object code. | |
(e) Each time you redistribute the Program or any Derivative | |
Work, the recipient automatically receives a license from 3dfx and | |
successor licensors to copy, distribute or modify the Program and | |
Derivative Works subject to the terms and conditions of the License. | |
You may not impose any further restrictions on the recipients' | |
exercise of the rights granted herein. You are not responsible for | |
enforcing compliance by third parties to this License. | |
(f) You may not make any use of the GLIDE trademark without | |
the prior written permission of 3dfx. | |
(g) You may not copy, modify, sublicense, or distribute the | |
Program or any Derivative Works except as expressly provided under | |
this License. Any attempt otherwise to copy, modify, sublicense or | |
distribute the Program or any Derivative Works is void, and will | |
automatically terminate your rights under this License. However, | |
parties who have received copies, or rights, from you under this | |
License will not have their licenses terminated so long as such | |
parties remain in full compliance. | |
4. MISCELLANEOUS | |
4.1 Acceptance of this License is voluntary. By using, modifying or | |
distributing the Program or any Derivative Work, you indicate your | |
acceptance of this License to do so, and all its terms and conditions | |
for copying, distributing or modifying the Program or works based on | |
it. Nothing else grants you permission to modify or distribute the | |
Program or Derivative Works and doing so without acceptance of this | |
License is in violation of the U.S. and international copyright laws. | |
4.2 If the distribution and/or use of the Program or Derivative Works | |
is restricted in certain countries either by patents or by copyrighted | |
interfaces, the original copyright holder who places the Program under | |
this License may add an explicit geographical distribution limitation | |
excluding those countries, so that distribution is permitted only in | |
or among countries not thus excluded. In such case, this License | |
incorporates the limitation as if written in the body of this License. | |
4.3 This License is to be construed according to the laws of the | |
State of California and you consent to personal jurisdiction in the | |
State of California in the event it is necessary to enforce the | |
provisions of this License. | |
