Contact movement

Post by Gab68 »

Hello
I have a project for modelling joint movement. It is essentially about rolling a bone in a socket. The movement is not an axial rotation. It is rolling one object along surface of another.
Does this software have functionality to figure out the contact, location, etc.?
I would appreciate any suggestions
Thanks in advance

Hi Gab

This is an interesting project. We do not have a high level solution, but we have tools to implement it in your application.
What I think would be involved there is:
- Collision detection (Collision Path, Collision and Metrics samples)
- Obtaining surface points with surface normal (Collision samples, Metrics sample)
- Building local axes (frames) on surfaces of the objects using the above info and IFrame_DG
- Moving the contact frame and making transforms between contact and local frame of the object(s)
ToLocalFrame(IFrame_DG), ToGlobalFrame(IFrame_DG) http://www.dynoinsight.com/Help/V6_0/In ... LocalFrame

Please get in touch if you need our help. We are thinking about this from time to time. I will record this as the first enquiry. We might doo it sooner if we have enough interest

Good luck
