This document pertains to the use and distribution of the POVLAB 3D Modeller. It
applies to all POVLAB program source files, executable (binary) files, scene
files, documentation files, help file, bitmaps and INI files contained in
official POVLAB package. All of these are referred to here as "the software".
The POVLAB Authors reserves the right to revise these rules in future versions
and to make additional rules to address new circumstances at any time.
Although it is distributed as freeware, it is NOT PUBLIC DOMAIN.
The copyrighted package may ONLY be distributed and/or modified according to the
license granted herein. The spirit of the license is to promote POVLAB as a
standard modeller, provide the full POVLAB package freely to as many users as
possible, prevent POVLAB users and developers from being taken advantage of,
enhance the life quality of those who come in contact with POVLAB. This license
was created so these goals could be realized. You are legally bound to follow
these rules, but we hope you will follow them as a matter of ethics, rather than
fear of litigation.
USAGE PROVISIONS
Permission is granted to the user to use the software and associated files in
this package to create and render images. The use of this software for the
purpose of creating images is completely free. The creator of a scene file and
the image created from the scene file, retains all rights to the image and scene
file they created and may use them for any purpose commercial or non-commercial.
The user is also granted the right to use the scenes files, fonts, bitmaps, and
include files distributed in sub-directories in their own scenes. Such
permission does not extend to files in the SCENE directory or all
sub-directories. The SCENE files are for your enjoyment and education but may
not be the basis of any derivative works.
GENERAL RULES FOR ALL DISTRIBUTION
The permission to distribute this package under certain very specific conditions
is granted in advance, provided that the following conditions are met.
These archives must not be re-archived using a different method without the
explicit permission of the POVLAB Authors. You may rename the archives only to
meet the file name conventions of your system or to avoid file name duplications
but we ask that you try to keep file names as similar to the originals as
possible. (For example: POVLAB40.ZIP to POVLAB.ZIP)
Ready-to-run unarchived distribution on CD-ROM is also permitted if the files
are arranged in the POVLAB standard directory or folder structure as though it
had been properly installed on a hard disk.
You must distribute a FULL PACKAGE of files as described in the next section.
No portion of this package may be separated from the package and distributed
separately other than under the conditions specified in the provisions given
below.
Non-commercial distribution in which no money or compensation is charged (such
as a user copying the software for a personal friend or colleague) is permitted
with no other restrictions.
Teachers and educational institutions may also distribute the material to
students for free or they may charge minimal copying costs if the software is to
be used in a course.
DEFINITION OF "FULL PACKAGE"
A "full package" contains an executable program, documentation, and sample
scenes.
Distributors must distribute a full package.
This software may ONLY be bundled with other software packages according to the
conditions specified in the provisions below.
CONDITIONS FOR SHAREWARE/FREEWARE DISTRIBUTION COMPANIES
Shareware and freeware distribution companies may distribute the software
included in software-only compilations using media such as, but not limited to,
floppy disk, CD-ROM, tape backup, optical disks, hard disks, or memory cards.
This section only applies to distributors of collected programs. Anyone wishing
to bundle the package with a shareware product must use the commercial bundling
rules.
CONDITIONS FOR ON-LINE SERVICES AND BBS'S INCLUDING INTERNET
On-line services, BBS's and internet sites may distribute the POVLAB 3D modeller
software under the conditions in this section. Sites which allow users to run
POVLAB from remote locations must use separate provisions in the section below.
The archives must all be easily available on the service and should be grouped
together in a similar on-line area.
It is strongly requested that sites remove prior versions of POVLAB to avoid
user confusion and simplify or minimize the support efforts.
The site may only charge standard usage rates for the downloading of this
software. A premium may not be charged for this package. I.E. CompuServe or
America On-Line may make these archives available to their users, but they may
only charge regular usage rates for the time required to download.
PERMITTED MODIFICATION AND CUSTOM VERSIONS
Although the full source code for POVLAB is distributed, there are strict rules
for the use of the source code. The source distribution is provided to :
- promote the porting of POVLAB to hardware and operating systems which the
POVLAB Authors cannot support.
- promote experimentation and development of new features to the core code which
might eventually be incorporated into the official version.
- provide insight into the inner workings of the program for educational
purposes.
These license provisions have been established to promote the growth of POVLAB
and prevent difficulties for users and developers alike. Please follow them
carefully for the benefit of all concerned when creating a custom version.
The user is granted the privilege to modify and compile the source code for
their own personal use in any fashion they see fit. What you do with the
software in your own home is your business.
However severe restrictions are imposed if the user wishes to distribute a
modified version of the software, documentation or other parts of the package
(here after referred to as a "custom version"). You must follow the provisions
given below. This includes any translation of the documentation into other
languages or other file formats.
A "custom version" is defined as a fully functional version of POVLAB with all
existing features intact. ANY OTHER USE OF ANY POVLAB SOURCE CODE IS EXPRESSLY
PROHIBITED. The POVLAB Authors does not license source code for any use outside
POVLAB. No portion of the POVLAB source code may be incorporated into another
program unless it is clearly a custom version of POVLAB that includes all of the
basic functions of POVLAB.
All executables, documentation, modified files and descriptions of the same must
clearly identify themselves as a modified and unofficial version of POVLAB. Any
attempt to obscure the fact that the user is running POVLAB or to obscure that
this is an unofficial version expressly prohibited.
POVLAB may not be linked into other software either at compile time using an
object code linker nor at run-time as a DLL, ActiveX, or other system. Such
linkage can tend to blur the end user's perception of which program provides
which functions and thus qualifies as an attempt to obscure what is running.
To allow POVLAB to communicate with outside programs, the official versions of
POVLAB include several internal communication "hooks" for it to call other
tasks, often called an Application Programming Interface, or API. For example:
the generic part of POVLAB provides operating system shell-out API commands.
Modification to these APIs or other officially supported communication
mechanisms to increase functionality beyond that of the official version IS
EXPRESSLY PROHIBITED.
CONDITIONS FOR DISTRIBUTION OF CUSTOM VERSIONS
If your re-compiled version meets all requirements for custom versions listed
above, the following conditions apply to its distribution:
You must provide all POVLAB support for all users who use your custom version.
You must provide information so that user may contact you for support for your
custom version. The POVLAB authors is not obligated to provide you or your users
any technical support.
Include contact information in the in the source code and insure that the
program prominently displays this information. Display all copyright notices and
credit screens for the official version.
Custom versions may only be distributed as freeware. You must make all of your
modifications to POVLAB freely and publicly available with FULL SOURCE CODE to
the modified portions of POVLAB and must freely distribute full source to any
new parts of the custom version. The goal is that users must be able to
re-compile the program themselves using readily available compilers and run-time
libraries and to be able to further improve the program with their own
modifications.
You must provide documentation for any and all modifications that you have made
to the program that you are distributing. Include clear and obvious information
on how to obtain the official POVLAB.
The user is encouraged to send enhancements and bug fixes to the POVLAB Authors,
but the authors are in no way required to utilize these enhancements or fixes. By
sending material to the authors, the contributor asserts that he owns the materials
or has the right to distribute these materials. He Authorsizes the Authors to use
the materials any way they like. The contributor still retains rights to the
donated material, but by donating, grants unrestricted, irrevocable usage and
distribution rights to the POVLAB Authors. The Authors doesn't have to use the
material, but if we do, you do not acquire any rights related to POVLAB. The
authors will give you credit as the creator of new code if applicable.
Include a copy of this document (LEGAL.TXT).
CONDITIONS FOR COMMERCIAL BUNDLING
Vendors wishing to bundle POVLAB with commercial software (including shareware)
or other distribution not already described above must first obtain explicit
permission from the POVLAB Authors. Such permission is rarely granted. The POVLAB
Authors will decide if such distribution will be allowed on a case-by-case basis
and may impose certain restrictions as it sees fit. The minimum terms are given
below. Other conditions may be imposed.
The product must be an existing product that has proven itself as commercially
viable without POVLAB included.
The inclusion of POVLAB should be promoted only as a free bonus and not as a
feature designed to encourage customers to purchase or upgrade solely for the
POVLAB capability.
Purchasers of your product must not be led to believe that they are paying for
POVLAB. Any mention of the POVLAB bundle on the box, in advertising or in
instruction manuals must be clearly marked with a disclaimer that POVLAB is free
software and can be obtained for free or nominal cost from various sources.
Include clear and obvious information on how to obtain the official POVLAB.
You must provide all POVLAB support for all users who acquired POVLAB through
your product. The POVLAB Authors is not obligated to provide you or your
customers any technical support.
Include a credit page or pages in your documentation for POVLAB.
If you modify any portion POVLAB for use with your hardware or software, you
must follow the custom version rules in addition to these rules.
Include contact and support information for your product.
Include a full user package as described above.
Include the POVLAB internet site (http://www.povlab.org).

POVLAB Authors members are compensated participants and which the POVLAB
has given approval.
Without specific approval, distributors (whether free or
commercial) must not claim or imply in any way that the POVLAB Authors
officially endorses or supports the distributor or the product
(such as CD, book, or magazine) associated with the distribution.
You may not claim or imply that the POVLAB Authors derives any benefit
from your distribution.

other person or organization delegated by the copyright holder for the
