Dennis, If you havn't written this code (to translate 3DS files) already, I'd suggest you spend your time in more useful pursuits, like writing IPAS applications. I'd bet there is a much larger market for IPAS applications than for raytracing 3DS files. James

James, This may be a stupid question, but what is IPAS? Dennis Bragg

Dennis, I quote from Appendix C of the 3DS reference manual: IPAS processes are Phar Lap 386 programs that share memory buffers with Autodesk 3D Studio for high speed inter-program communication. The four types of processes have these DOS file extender names: IXP Image-processing eXternal Process PXP Proceedural modeling eXternal Process AXP Animated stand-In eXternal Process SXP Solid pattern eXternal Process The Acronym IPAS is derived from the first letter of the name of each type of process. Autodesk 3D Studio includes sample programs for fourteen IPAS applications. They are useful for their intrinsic utility and as examples of IPAS programming. The sample processes illustrate techniques that IPAS applications can use to extend the built-in features of Autodesk 3D Studio. The capabilities of Autodesk 3D Studio for modeling, rendering, and animation are merely a jumpping-off point. Using IPAS applications, you can infinitely extend Autodesk 3D Studio with programs that proceedurally model, render, animate and image-process 3D scenes. Hope that describes it adaquately enough. If not I suggest you contact Gary Yost or Autodesk Developer Services (John Sergeni) for more details. James

Jack, Does IPAS open the door for programs that will assist in Keyframing with accurate object collision detection, customized object link/hierarchy, etc, etc..? I hope all the motivated programmers out there are working as we speak! JR

Motivated programmers would be working on it, if they could get the IPAS developers kit… 🙁 – Still Waiting…

My goodness, we must be having parallel thoughts, here! I just answered the same thread by quoting from the manual too! Amazing! Course, not quite to the same degree, but interesting point. (to me at least). I'm very keen to see some off the shelf IPAS applications come out, but it's a bit like the mesh library situation: I'll probably only buy them when I have a project which will pay for them. I'm not quite at the point where I can buy any software that takes my fancy without being able to cost justify it. Boring but pragmatic I suppose, probably a lot to do with the old lady, who keeps me in line when my inherent impulsive spending streak gets out of hand. I was going to buy Mannequin by Humancad but decided to wait-and-see instead. Now I'm glad I didn't get it since I've never had a situation where I couldn't utilize something else less expensive, like 3d-people by Technical Designs. Do you have the Imagetects CD-Rom, and if so do you consider it worthwhile, or, if not, do you scan your own textures?

Martin, I'll bet that IPAS applications will be afforadble enough to buy even if you don't need them immeaditly. (I hope) No, I don't have the image cels CD, I scan the ones I need myself, besides with the r2 CD you shouldn't need Image cels right away. James

James, Thanks for the enlightenment. IPAS sounds promising. I will investigate further. Dennis Bragg
