3DFX GLIDE Source Code General Public License
6
This license is for software that provides a 3D graphics application
7
program interface (API).The license is intended to offer terms similar
8
to some standard General Public Licenses designed to foster open
9
standards and unrestricted accessibility to source code. Some of these
10
licenses require that, as a condition of the license of the software,
11
any derivative works (that is, new software which is a work containing
12
the original program or a portion of it) must be available for general
13
use, without restriction other than for a minor transfer fee, and that
14
the source code for such derivative works must likewise be made
15
available. The only restriction is that such derivative works must be
16
subject to the same General Public License terms as the original work.
18
This 3dfx GLIDE Source Code General Public License differs from the
19
standard licenses of this type in that it does not require the entire
20
derivative work to be made available under the terms of this license
21
nor is the recipient required to make available the source code for
22
the entire derivative work. Rather, the license is limited to only the
23
identifiable portion of the derivative work that is derived from the
24
licensed software. The precise terms and conditions for copying,
25
distribution and modification follow.
30
2.1 This License applies to any program (or other "work") which
31
contains a notice placed by the copyright holder saying it may be
32
distributed under the terms of this 3dfx GLIDE Source Code General
35
2.2 The term "Program" as used in this Agreement refers to 3DFX's
36
GLIDE source code and object code and any Derivative Work.
38
2.3 "Derivative Work" means, for the purpose of the License, that
39
portion of any work that contains the Program or the identifiable
40
portion of a work that is derived from the Program, either verbatim or
41
with modifications and/or translated into another language, and that
42
performs 3D graphics API operations. It does not include any other
45
2.4 "Modifications of the Program" means any work, which includes a
46
Derivative Work, and includes the whole of such work.
48
2.5 "License" means this 3dfx GLIDE Source Code General Public License.
50
2.6 The "Source Code" for a work means the preferred form of the work
51
for making modifications to it. For an executable work, complete source
52
code means all the source code for all modules it contains, any
53
associated interface definition files, and the scripts used to control
54
compilation and installation of the executable work.
56
2.7 "3dfx" means 3dfx Interactive, Inc.
59
3. LICENSED ACTIVITIES

(a) you conspicuously and appropriately publish on each copy
66
an appropriate copyright notice (3dfx Interactive, Inc. 1999), a notice

82
3.2 MODIFICATION OF THE PROGRAM/DERIVATIVE WORKS - You may modify your
83
copy or copies of the Program or any portion of it, and copy and
84
distribute such modifications subject to the provisions of section 3.3
85
and provided that you also meet all of the following conditions:
87
(a) you conspicuously and appropriately publish on each copy
88
of a Derivative Work an appropriate copyright notice, a notice that
89
recipients who wish to copy, distribute or modify the Derivative Work
90
can only do so subject to this License, and a disclaimer of warranty
91
as set forth in section 5;
93
(b) keep intact all the notices that refer to this License and
94
to the absence of any warranty; and

terms of this License.
108
(f) You do not make any use of the GLIDE trademark without the
109
prior written permission of 3dfx.

113
such interactive use, to print or display an announcement as follows:
115

(h) The requirements of this section 3.2 do not apply to the
124
modified work as a whole but only to the Derivative Work. It is not
125
the intent of this License to claim rights or contest your rights to
126
work written entirely by you; rather, the intent is to exercise the
127
right to control the distribution of Derivative Works.
132
(a) All copies of the Program or Derivative Works which are
133
distributed must include in the file headers the following language
136
"THIS SOFTWARE IS SUBJECT TO COPYRIGHT PROTECTION AND IS OFFERED

154
(b) You may distribute the Program or a Derivative Work in
155
object code or executable form under the terms of Sections 3.1 and 3.2
156
provided that you also do one of the following:
158
(1) Accompany it with the complete corresponding
159
machine-readable source code, which must be distributed under the
160
terms of Sections 3.1 and 3.2; or,
162
(2) Accompany it with a written offer, valid for at
163
least three years, to give any third party, for a charge no more than
164
your cost of physically performing source distribution, a complete
165
machine-readable copy of the corresponding source code, to be
166
distributed under the terms of Sections 3.1 and 3.2 on a medium
167
customarily used for software interchange; or,
169
(3) Accompany it with the information you received as
170
to the offer to distribute corresponding source code. (This alternative
171
is allowed only for noncommercial distribution and only if you received
172
the program in object code or executable form with such an offer, in
173
accord with Subsection 3.3(b)(2) above.)
175
(c) The source code distributed need not include anything
176
that is normally distributed (in either source or binary form) with
177
the major components (compiler, kernel, and so on) of the operating
178
system on which the executable runs, unless that component itself
179
accompanies the executable code.
181
(d) If distribution of executable code or object code is made
182
by offering access to copy from a designated place, then offering
183
equivalent access to copy the source code from the same place counts
184
as distribution of the source code, even though third parties are not
185
compelled to copy the source along with the object code.
187
(e) Each time you redistribute the Program or any Derivative
188
Work, the recipient automatically receives a license from 3dfx and
189
successor licensors to copy, distribute or modify the Program and
190
Derivative Works subject to the terms and conditions of the License.
191
You may not impose any further restrictions on the recipients'
192
exercise of the rights granted herein. You are not responsible for
193
enforcing compliance by third parties to this License.
195
(f) You may not make any use of the GLIDE trademark without
196
the prior written permission of 3dfx.
198
(g) You may not copy, modify, sublicense, or distribute the
199
Program or any Derivative Works except as expressly provided under
200
this License. Any attempt otherwise to copy, modify, sublicense or
201
distribute the Program or any Derivative Works is void, and will
202
automatically terminate your rights under this License. However,
203
parties who have received copies, or rights, from you under this
204
License will not have their licenses terminated so long as such
205
parties remain in full compliance.
210
4.1 Acceptance of this License is voluntary. By using, modifying or
211
distributing the Program or any Derivative Work, you indicate your
212
acceptance of this License to do so, and all its terms and conditions
213
for copying, distributing or modifying the Program or works based on
214
it. Nothing else grants you permission to modify or distribute the
215
Program or Derivative Works and doing so without acceptance of this
216
License is in violation of the U.S. and international copyright laws.
218
4.2 If the distribution and/or use of the Program or Derivative Works
219
is restricted in certain countries either by patents or by copyrighted
220
interfaces, the original copyright holder who places the Program under
221
this License may add an explicit geographical distribution limitation
222
excluding those countries, so that distribution is permitted only in
223
or among countries not thus excluded. In such case, this License
224
incorporates the limitation as if written in the body of this License.
226
4.3 This License is to be construed according to the laws of the
227
State of California and you consent to personal jurisdiction in the
228
State of California in the event it is necessary to enforce the
229
provisions of this License.

THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
