"FXT1 advanced texture compression is provided free to anyone who wants to create and accelerate content utilizing many more texture images and higher resolution textures, all with the highest possible image quality. FXT1 texture compression provides equal to or better compression ratios than any available hardware compression scheme and is supported on all future 3dfx products. With up to four compression schemes used in the encoding of each texture, FXT1 provides the most accurate texture compression available, providing little or no loss in image quality. Decoding FXT1 textures can be done transparently in the 3D hardware at run-time, or decoded in software and converted to another hardware-supported texture format. In addition, cross platform 3D API (Glide(tm), OpenGL(r), and Direct3D(tm)) support for FXT1 allows developers to use it on Windows, Macintosh and Linux platforms without any additional coding by the developer. Finally, 3dfx provides free tools, and the associated source code, to encode and decode compressed textures to allow the user community to create newer and better encoding algorithms. These tools include command line utilities and a Photoshop(r) plug-in and are currently available for download below."

"We encourage developers to make suggestions and submit new source for possible inclusion with future versions of FXT1. We believe texture compression is absolutely necessary to creating compelling next generation 3D games. Please tell us what you think about how we can make it better. To facilitate discussion on FXT1 and allow people to make suggestions, we have set up a newsgroup and email alias."

"For now, we'd like to ask that any new ideas or source code be sent to FXT1@3dfx.com. Periodically, we'll review any suggestions or new source code and query prominent newsgroup users as to what they think should be included in each new revision. If we get a lot of response from developers, we'll set up a public source code base, where anyone can upload new source code."
