+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.

+

+

+5. NO WARRANTIES

+

+	5.1 TO THE EXTENT PERMITTED BY APPLICABLE LAW, THERE IS NO WARRANTY

+	FOR THE PROGRAM. OR DERIVATIVE WORKS THE COPYRIGHT HOLDERS AND/OR

+	OTHER PARTIES PROVIDE THE PROGRAM AND ANY DERIVATIVE WORKS"AS IS"

+	WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING,

+	BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND

+	FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY

+	AND PERFORMANCE OF THE PROGRAM AND ANY DERIVATIVE WORK IS WITH YOU.

+	SHOULD THE PROGRAM OR ANY DERIVATIVE WORK PROVE DEFECTIVE, YOU ASSUME

+	THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.

+

+	5.2 IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW WILL 3DFX

+	INTERACTIVE, INC., OR ANY OTHER COPYRIGHT HOLDER, OR ANY OTHER PARTY

+	WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM OR DERIVATIVE WORKS AS

+	PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL,

+	SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR

+	INABILITY TO USE THE PROGRAM OR DERIVATIVE WORKS (INCLUDING BUT NOT

+	LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES

+	SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM OR

+	DERIVATIVE WORKS TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH

+	HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH

+	DAMAGES.
