cheap curve collisions

[pgrochola]

Hi,

I have a bunch of curves stuck on a surface (for fur groom).

I'm trying to avoid going through dops to do geometry collisions.

I'm developing an idea of using the velocity of the collision object to calculate the rotation of a curve at the base.

At the moment I'm stuck on how you define the pivot in the rotate node in vops.

The attached example illustrates what I'm trying to achieve.

Has anyone done something similar?

Thanks

One way to do cheap collisions would be if the curves to point-cloud-lookup themselves and then you do something with that. Another thing would be to make a volume out of it (normals, of v or something) and then use that to advect.

Just some ideas.

thanks Macha.

I've also looking into using a sop solver for this.

Seems really promising.

I'll post my finding if I come with anything decent.

Cheers

Here is a quick and dirty hack using the sop solver. (no dynamics)

Could be useful if speed is more important than accuracy.
