Hash Fellow robcat2075 Posted June 12, 2012 Hash Fellow Posted June 12, 2012 If i pass any arbitrarily shaped object through another surface (lets start with something as simple as a plane) how can i capture the shape of the intersection on that surface at any moment? For example, the intersection of this torus with the plane would be a couple of ovals. How could I capture that? I can sort of get the edges of the object as they pass thru the plane by putting an orthogonal camera very close to the plane... TorusThroughPlane.mov ... but it misses pixels and I'd really like to have the shapes filled, not just the outlines. I'm trying to find a way to better simulate the disturbance an object makes immediately around it as it sits in a liquid. Being able to have an image of the intersection of the object with the plane of the liquid would be a part of that. Quote

I remember (very deep somewhere in my head) that using two booleans above eachother will invert them, right? (maybe I am confusing it with another software) See you *Fuchur* Quote

Hash Fellow robcat2075 Posted June 12, 2012 Author Hash Fellow Posted June 12, 2012 Here's a first attempt at using the derived map to create the meniscus effect that surrounds an object in a liquid. The match of the map to the object can be made much better, but the basic concept seems feasible... meniscus000.mov Quote
mouseman Posted June 13, 2012 Posted June 13, 2012 Be neat to try that with water, in a glass, with all of the right IORs (Index of Refractions). Quote
serg2 Posted June 14, 2012 Posted June 14, 2012 robcat2075 it's an interesting idea! Thank you! Quote
