I had a friend who recently wanted to make a pinching blob motion for an animation, and she used something where it checked if a point was a certain distance between two circles, and all points within that range were allowed. Is that kind of technique used?
I am still confused on what you are controlling in order to blend them together.
For example, what are those f referring to? Are they different sum of Gaussians centered at different points? Is it saying the distance from point p to point q is closer and closer (from .5 to .3) ?
@jelenak Sure; that doesn't sound too different from what's going on here.
@siliangl It's saying that we're looking at the set of points x such that f(x)=.5, or f(x)=.4, or f(x)=.3, rather than the set f(x)=0.
