#Motion Tracking Data?

I'm with Mechadeus, a CD-ROM producer in SF. (We did the Critical Path CD-ROM which is shipping now.) We're in production on another interactive movie which will use live action actors matted into 3D animations. We are going to use a motion tracking camera head, probably the one from Ultimatte, which will give us a data stream of camera postion information. We want to be able to move the camera and still matte into animations accurately. We'll wind up with an ASCII file of time / postion data. My question is… Does anyone know of IPAS or other utilities which we can buy which can translate ASCII camera postion data into 3D Studio keyframes. We could have one of our programmers write a custom IPAS routine to do this but it would be nice if a good one existed already. We don't want any more smoke to come out of our programmer's heads. Thanks in advance… Bill Niemeyer

Bill, 3ds can already accept ascii data for keyframe positions, I believe. Read up on the .vue file format in your manuals to see if it will do the trick for you.

Bill, I'm looking for the same thing, except for any pre-existing object in 3ds. the .vue file can be used but it does not get the data into the keyframer. it stays outside in the .vue file and positions things for the rendering. I need the paths to end up inside the keyframer. Let me know if you have any success. Steve Burdick 1520 Land O'Lakes Blvd. Lutz, FL 33549 (813) 948-0018

I looked at the .vue format but like you I want to import it into the keyframer directly. Also the .vue files get really messy on the size of models that we use. Looks like the solution is a KXP process but I haven't found it availible. Called Shreiber but they don't have it. Looks like a custom job, either from one of the IPAS developers or one we write ourselves. If I find any good news I will let you and the other people interested know.

I'm still looking also. Sounds like we are covering a lot of the same ground. Will let you know of any break throughs. The most likely people to have solved this problem would probably be those doing forensic animations for vehicular collisions. thanks, steve

I am also looking for something similar. I have been using Vista Pro. And just recently the guys from VRLI wrote a SCR2VUE converter which converts the paths you make in Vistapro and turns them into .vue files. But I just can't get the path back into 3DS. I had asked them to write this a couple of months ago, thinking you could import vue files and turn them into a path, or keyframes. This path would also be excellent for cars, or motorcycles or airplanes, going through the mountains. Does anyone have any suggestions. Thanx, Fred Nilsson

We are working on an IPAS routine that loads VistaPro binary DEMs, but it would also make sense to have it load VUE files in the Keyframer, too. I'll add that to the requested features list. If you have any other ideas about what this IPAS should do, be sure to send me a message in private e-mail.

One idea I had for bringing in the VUE file, is being able to use this path as not only a path for the camera but for a path of an object as well. That way we could have a car driving over a landscape or a jet flying through the landscape using VP3's makepath utility. This utility really makes nice path's. Let me know what you come up with. thanx, Fred Nilsson

Fredrik Nilsson, Could you tell me more about the make path utility you spoke of. I am interested. Thanks, Greg Kammer

Well, the MakePath utility, that comes on the new Vista Pro 3.1 CD, is a utility that easily lets you make paths that either fly, through a canyon or any mountain structures. You have control over most things, ie… bank, pitch, roll, speed, etc…also which type of aircraft, whether it be a glider or a jet. Also you could have the camera drive over the landscape in a car or a motorcycle. It's real simple to make a path, All you do is draw a spline path through the mountains then you can see a real time preview of your animation. It's really cool. Fred Nilsson
