Hi, thanks for your reply. How would you compare CDK with Sense 8 World Toolkit perhaps ? Advantages and disadvantages ? Technical Support ? Thanks

There is a file somewhere in the libraries here that does an early comparison between CDK and WTK. Perhaps Jonas could point us to it, I have forgotten where it is myself, but as I recall it had the name of both in the title (i.e. CDKWTK.zip or something like that). The big advantage of CDK is the interface to the other Autodesk products. No one else is doing a very tight job of it. If you wish to interact with either AutoCAD or 3D Studio, CDK has more to offer beyond just loading in DXF files. Sense8 is a very seasoned and proven product, while CDK is still trying to come into its own. I do remember when there was only BETA versions available from Sense8 a few years ago as well though. It takes a couple of versions to grow up, I think… Sense8 has great technical support. Since so few of the other CDK dealers knew how to use it, we have generally fielded most of the tech support issues so far (at least it seems so to me from the number of angy/frustrated calls) as Autodesk does not offer direct tech support for end users. We generally helped anyone get CDK up and compiling the demos at no charge, but beyond that we have to offer tech support contracts to maintain the ability to help new CDK developers. However, that is changing now with the entrance of Ithaca Software to the picture. They are now in charge of such things I believe so it should improve drastically I am told. They should be able to offer much more support than the other CDK dealers could and I believe the plan is to do so through the existing dealer channel. This means that any CDK dealer should be able to get you some answers by using our new 'Ithaca' dealer resource. This is a good thing. The more people that get support, the better for CDK as a whole, which is what Autodesk is trying to nurture. I would not tell you that CDK is 100% the best choice available, as it really depends of what you plan to do with it. If integrating with Autodesk is important, CDK is a better choice, in my opinion. Also, I believe that CDK has more higher level physics calls that Sense8, but I haven't kept up with the latest releases of WTK so if anyone has a different opinion on that point, I would like to learn about it. That is still my understanding. Not to sound too wishy washy, I must say however, that the folks at Sense8 are great developers and have an excellent product. It does not require C++ or such a high level platform for development as CDK either. Some argue this is good, some say it is bad. I think it depends on the application desired as the end product and what your resources are. We would be happy to talk more about providing CDK or WTK or any information that could help you in what you are planning to do. Just drop me a line and let me know how to get in touch or call me at (904) 376-1529, or email micgreen@freenet.ufl.edu, or Cserve mail. We are in the midst of moving our office this month so leave voice mail or Cserve mail if you can't get directly through to me. I hope this helps a little bit. Angela Pate

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

Hi Jerry, << I did a review of CDK that was published in Software Development (Miller Freeman Pub) in Dec 93. >> Have you gotten to see CDK Version 2.0 at any of the recent road shows? jonas[adesk]

Jonas, Unfortunately, none of the road shows have been in my area, or I havent heard of them. I'm in the Ventura County CA area (North of LA). I'd like to check out V2 sometime. I've been looking at the Virt.Navigator demo. My big problem with CDK is that I only have a VGA system, no accelerator boards. Jerry
