AxisSweep3 looks compact and efficient. I'm curious though, why doesn't it use stabbing numbers for fast insertion, removal, and queries? Using the stabbing numbers it wouldn't be necessary to add/remove overlapping pairs when sorting the endpoints of each AABB. As it is now overlapping pairs are b...

Well, first off, thank you both for your help! :wink: So, I wrote this little program to test cancellation when subtracting two nearly equal values. // Both delta0 and delta1 suffer from rounding // errors because they're not representable in IEEE-754 float delta0 = 0.432343547394f; float delta1 = 0...

Gino's Book - Robustness section
Hi, This question is mainly directed to Gino van den Bergen as it is a little doubt from his book. However, anyone able to help is very welcome. :) So, from page 59 I'm not understanding what Gino is trying to explain in the phrase that starts with "Assume". It's located right in the botto...

EPA
I have implemented EPA these days and ran it to calculate the penetration depth of two boxes but I'm facing a problem for which I don't have a solution. Both boxes have extents 1 in all directions and one box is at (0.5f,0.0f,0.0f) and the other is at (-0.5f,0.0f,0.0f). So, the penetration depth sho...
