This seems like an insanely expensive task for a complicated mesh. Will we see algorithms for this?

richardnnn

What's the difference between an intersection happened for geometry and a collision occurred for animation?

goose_r_s

Do people use these checks to run physics simulations with 3d meshes? Such as preventing collisions?

fzeng

How does collision detection work in video games where there can be thousands of moving objects at any time?

bobzhangyc

What is the definition for intersection? Does this mean edge intersection?

Alan7996

Some elements might want to be able to intersect with other elements while some elements may not wish to do so (e.g. liquid vs solid). How can we differentiate these qualities in meshes/animation?

anon

For unintended intersections, are they always checked for everywhere in a render or could a render potentially ignore them in certain places if it determines if it would not be visible, or would that have a further adverse effect?

anj

I assume that the mesh would also depend on the material/physics of the material. Would you just check for collision and do another action according to the material?

spidey

How do we detect these intersections and collisions?

ant123

I'm assuming we'd use vector calculus (similar to line intersection of some kind, but also with planes/meshes) to determine this?
