Contents Functions Classes Topics User Forum CVS License Introduction Installation Intent of License (This section is informal and not legally binding.) This library is free code-- you can use it without charge and it is minimally legally encumbered. Unlike some other free libraries, we <u>do not</u> require you to release your source code or make your own program open source. I intend the license (below) to protect me and the other contributors from liability and allow you to use the source however you want. You can make your own closed or open-source programs, sell them, give them away, whatever. You have an obligation to say "this software is based in part on the work of the Independent JPEG Group" in your documentation or application help if you use the G3D::GImage class because it is based on the IJG library. The OpenGL headers and ZLib headers included may be freely distributed provided their copyright notices remain intact. For convenience, G3D::license is a function that returns the license string you must put in your documentation. G3D::GApp will automatically write a file (g3d-license.txt) to disk with the contents of this license unless you tell it not to. Most of the data resources have either entered the public domain and have been in several published papers or are data that I have explicitly received permission to distribute with G3D. The G3D fonts are actually font images, not TrueType font descriptions and may be freely distributed. As a rule of thumb, you can freely use and distribute anything you find in the data directory but may need permission to use it in a commercial product. Check the various copyright.txt files in the data directories for specific information. You are required by the BSD license to acknowledge G3D in your documentation. This can be as minimal as a note buried in the fine print at the end of a manual or a text file accompanying your program. I appreciate it if you acknowledged the library more publicly but you aren't required to. Likewise, you are encouraged but not required to submit patches to improve the library for the benefit of all. E-mail me with bugs, patches, and questions. -Morgan McGuire <matrix@graphics3d.com> License G3D is licensed under the BSD license, with portions controlled by the IJG license and PNG Reference Library license This product uses software from the G3D project (http://g3d-cpp.sf.net) Copyright © 2000-2006, Morgan McGuire All rights reserved.

You must also agree to be bound by the terms of the Independent JPEG Group license for the portions of this library that are based on the work of the Independent JPEG Group, if you use those portions. Note: if you do not use the G3D::GImage class, this clause does not apply to you because the linker will strip that code from your project. The IJG-README.TXT file contains the Independent JPEG Group license. Hosted by
