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

Title: Comparison of WTK and CDK
Keys: WTK CDK COMPARISION TEXT
This pkzip2.04g archive contains a comparison of the Sense8 World Tool Kit and
the Autodesk Cyberspace Development Kit. It was originally uploaded to the
Amulett BBS and then posted to USENET's sci.virtual-worlds. It is freely
distributable.

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.

Hi Jerry,
<< I did a review of CDK that was published in Software Development (Miller

Have you gotten to see CDK Version 2.0 at any of the recent road shows?

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.
