I guess that's because the concepts transfer nicely from 2d to 3d. E.g. the math for circle/circle collision is basically the same as the one for sphere/sphere collision.
- bruce343434 3y agoNot really for more complicated meshes however, which compose planar geometries to form a solid. For 2 objects A and B you could iterate all pairs of planes that they have to see if there's any overlap, and although that works out as "elegant" math, not so elegant performance. Also, it won't yield a manifold.
- fho 3y agoNo, but on some level line and plane equations are similar too. It's more about splitting bodies into convex parts to speed up the calculations. (tbh it's been 20 years since I did that by hand ... but I would assume that the underlying math has not changed since then)
