Real time collision and object navigation

[Jeff]

When two objects are linked, the destination object (car) will follow after the source (haptic device). If you want the car to follow a different path and go over the cylinder while the device goes through it, don't use a link. You can update the car's X,Z position every frame based on the device position and calculate its Y position based on the intersection of the car and cylinder at that point. To update the car's position every frame register a function with the vizact.onupdate command.
