Kyal CundallSpline Dynamics - Secure anchor points to prevent rotation
by on Oct 1, 2015 at 8:22:57 am


I am attempting to setup a dynamic model of bluetooth earphones with the cable connecting the earpieces applied with spline dynamics. I have no problem setting up the initial anchor points, and even found a way to attach the remote using the align to spline tag.

The problem is that the cable is not round it is made from a sweep nurbs consisting of a spline and a rounded rectangle. When I run the simulation the anchor points aren't locked in terms of rotation and they swivel as if they are attached by a hook or pin to the bottom of the earpiece. The remote also swivels unrelated to the direction of the cable but this is not as important as it only happens with big movements andit is probably unrelated to spline dynamics.

Is there any way of preventing the anchor points from spinning or swivelling around? Please help me!!!

Thanks in advance,
