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.
