[solved] getting a smooth connection between curve and geometry

Recommended Posts

Posted (edited)

I've got a curve that I want to attach to a piece of geometry. The connection should be smooth, more like roots of a tree, and not with a hard angle. 

How can I make my curve follow the shape of the surface I want it to connect to for a bit? 

Everything I came up with was either not really working or way too complex for this relatively simple idea. Just see the picture for a more elaborate description of what I want to achieve. Red = wrong, green = the kind of connection I'm looking for, following the target object's curvature for a bit.

That is pretty neat. Not really true collision detection, but it tracks a deformed surface OK.

Yeah you could transfer the normals from the geometry to the curves afterwards, and ray them to the surface. And then some more smoothing and resampling. Could be a little jittery though.
