Animated Sweep Nurbs with Cloth(Balloon)

[octomber]

Hi All, I was wondering how I get an animated Sweep Nurbs combined with the balloon tag. BTW: Sweep Nurbs static works well.

Why an animated sweep nurbs? Imagine applying some insulation foam or caulk with a cartridge gun and as it is dispensed the foam/caulk would expand over time while applying goes on.

Thanks a lot and sunny regards, Tom

Hi Tom,

Here is an alternative, I believe that Dynamic and Simulation have their place, but I think a simpler and more controllable solution is better here.

The idea is to have a Spline defined (which you might have already) and use this in a Volume setup.
CV4_2025_drs_25_ANfg_01.c4d

This allows to define and animate the "thickness" of the material while animating a Spline Interface (see image)

This allows for a very fast animation setup.

An SDF Dilate Erode can be set up for a Global size change to create an even more detailed setup for the animation.

The cube is there as an example that the solution can be defined by a geometry Context (subtract)

Let me know if that works for you.

Cheers
