Hi there, I have a client interested in doing Accident reconstruction and what he's calling "forensic animation". Since these are being used in court they need to be accurate to a certain degree. What I'm wondering is can a high enough degree of accuracy be applied to a 3d animation in 3D studio to hold up in court. Are motion modules like Digimation's Dynamic motion IPAS good enough to hold up in court. If anyone else is doing these types of animations with 3D studio are there and tips you can pass on? Any help would be great. Thanks, James J. LaPlante AEON Interactive

Each case I have come across varies in the degree of accuracy required. Mostly what is required is a depiction which can pass a "reasonableness test" , that is, it is frequently understood that you were not there and you are presenting one side of the story as told to you. The reconstruction cannot exceed the accuracy of the available data as documented by the court evidence. Another very important factor is the opinions of the expert witness(es). You may want to VERY carefully document everything you create so as to have a logical trail for how you came to include each pertinent detail. You want a tie to documented fact or someone else's expert opinion in writing. It would be best to leave out anything that does not directly apply to the case. The opposing lawyers will pick apart any little thing they can find. Also, try to stay detached from the case. Ask for data, and expert opinion, stay away from hearsay. On the bright side you may get called as an expert witness and get to charge $$$. <g>

Sounds like you need to attend the 1995 Forensic Animation Seminar Atking Place August 14th right here in Wisconsin. E-Mail me your Snail Mail and Phone information or better yet if you have a Fax. Please Make sure it's E-Mail. Murph'

Murph – As the Forensic Animation seminar gets closer we can put a line or two in the NewsFlash so more members and visitors will be aware of it. Remind me. Anne

I'll Take you up on it, there's a great need for this type of information and I've put together what I beleive to be a very worthwhile 3D Artists Seminar and Conference Program this year. Murph'

James, I am interested in the seminar. Is it for the state of WI only? I'd like to consider attending. Where in Wisconsin is the seminar? Jeff N-Image/ JRR Associates – Alabama

Jeff, Thank you for your interest. If possible could you Private E-Mail me your Address/Phone/Fax…in particular I could fax you conference information and registration forms. I'm still working on the Hotels, Motels list in the area. Thank You. Murph'

Hi Jeff. Not to steal any of Murph's thunder, but Autodesk University will also be offering a class on Forensic Animation if, for some unknown reason, Wisconsin is not a convenient venue for you. The instructor at AU will be Alec Jason, the forensic animator for the Mitchell Brothers trial–the one that really helped open the doors for forensic animation in the courtoom. It will be on the other side of the states in San Francisco in October. This year Autodesk has put a special emphasis on the multimedia side of the business and is offering over 100 classes/conferences/labs for 3D Studio, Animator Pro, Animator Studio, and all its other multimedia offerings. You can download the file from the NAAUG/Autodesk University library if you're interested. –Kelly

James; I just received your FAX on the seminar. I noticed that the Courtroom Animation seminar is to be video taped. Is there any chance of purchasing the video tape? I had already made plans to be at another week long seminar (for the family) the same week in August. I would most likely purchase the video if it isn't too expensive. Dennis

We want to make it a good value so everyone can afford it. I certainly will keep and all those interested posted. Thank you for your interest. Murph'

We use 3D Studio to do our animation but, to do our modeling we use SDRC, which is a solid modeling package which is exact in when modeling any type on structure. This is a little extreme but, we do animation for medical cases. Good Luck

Good Luck << I'm slightly familiar with the SDRC Package, As an Autodesk Dealer Several Year's ago I was looking at becoming authorized for SDRC so the AutoCad Product in tandem with SDRC could more effectively compete with other Much More Expensive Workstation software.

James, >>What I'm wondering is can a high enough degree of accuracy be applied to a 3d animation in 3D studio to hold up in court.<< I can't speak for anyone else, but in 3.5 years 3DS has had the accuracy needed to do the job. In the same amount of time, only once have I had to give my depostion. One week from trial the case settled or I would have had to testify. Maybe I'm just lucky. How about the rest of you forensic animatiors, whats your experience been? >>Are motion modules like Digimation's Dynamic motion IPAS good enough to hold up in court.<< I can't answer that question, but the expert should supply the numbers you will need, thats his/her job. Unless of course you are an expert yourself. >>If anyone else is doing these types of animations with 3D studio are there and tips you can pass on?<< You will need x,y and z(if there is elevation change) every 1/30 of a second. If you can, get the numbers in an ASCII file and then use the script file "Nodeftch.k3d" supplied with 3DSr4 and apply them to the appropiate objects. Its much easier than manual input and does not introduce typing errors. When you get done, the animation should represent the experts opinion of what happened. It should be just another aid to help the expert, just like a drawing or photgraphy would be. BTW, there is a list of 20 forensic animators in the index & info library, the file is called "Forlst.txt". All forensic animators are welcome to send me their info and I will include them in the list. Maybe if you told us alittle more about your case, then we could be more helpful.
