C4D: Suggestions on accomplishing this animation

Unity Engine
1

Hi all,

I’m just starting with Unity and have some questions concerning animation. I use C4D as my primary package, but in reading through the documentation for Unity it looks like only the most basic animation tracks can be brought in from C4D.

I’m not using Unity for game type stuff, but instead am trying to leverage it for medical simulation for instructional purposes. The end delivery for Unity is great, but I’m trying to figure out how I can accomplish various styles of animation.

As an example, look at the sample below. We have a vessel, and inside it is a 3-part catheter. These 3 parts are sweep NURBS and I’ve animated them to enter the vessel using the ‘growth’ parameter available on a sweep. They need to follow the curve of that vessel as they progress forward, so I’m not sure how I could accomplish such a move using only position and rotation.

Any thoughts on how this type of thing might be done? Thanks for any suggestions or thoughts.

Hello!

Just a thought.

Create an array of points that make a trajectory along your vessel, and make your catheter follow that trajectory :).

Just to update, the only route I could find to accomplish this is to actually rig my catheter as a “character” with joints. I guess this works, as it’s actually replicating the way it would work in the real world, but it’s a LOT more work. Ah well.
