You have some interesting stuff on your website. Thanks for sharing

Erwin, you've explained it before, not in great depth but ok... Here's the link, http://www.continuousphysics.com/Bullet/phpBB2/viewtopic.php?t=226 For the "at once" method, you can read this thread, see post from John Nagle: http://groups.google.com/group/comp.games.development.programmin...

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...

Hi,

Just to let you know that you can use http://rapidshare.de/ for such purposes.

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...

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...

I was following Gino's book to implement EPA and I misunderstood his closest_is_internal function. It's everything ok now. My bad!


Thanks anyway!

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...
