I remember that WTK/CDK comparison. I didnt write it, but uploaded it from the referenced areas. I think the original author is now working at Future Vision (makers of Sapphire 3d rendering board). It is a bit dated, as both products have been improved since April 93. WTK is now available as a Windows product and CDK has (finally) shipped an updated version. I did a review of CDK that was published in Software Development (Miller Freeman Pub) in Dec 93. It wasnt a glowing review, but did have some nice things to say about CDK (and some sharp jabs). I havent seen the latest CDK, but have WTK/Windows. However, my current favorite VR products are VRLib and VRT3. The former is a freeware VR program you can get in Bernie Roehl's new book "Playing God. Creating Virtual Worlds with Rend386" (Waite Group ISBN 1-878739-62-X. It is the latest incarnation of the freeware REND386 program and includes not only the basic VR renderer but an interpreted Object Oriented Animation system called BOB. The book/disk also includes some other freeware/shareware like NorthCAD for building objects. Interested users should also check out the 2Morrow World Builder demo over in CyberForum libraries. VRT3 is Superscape's latest VR program. It is the most expensive PC based VR program at several thousand dollars. At this time it does not support any of the 3d accelerator boards or any non-PC hardware. However, it includes a complete modeler, scripting system and (optionally) a C/C++ API. Both CDK and WTK rely on other programs to create & place the objects and a very seasoned C/C++ programmer to build the world applications. Jerry Isdale
