Thanks! It would be nice to hear how it performs on other systems. I'm especially interested in "simulation time". Since the debug info focuses on the map itself, it'll report wrong numbers of the "selected triangles". It won't add those are selected from the dwarf model, for exa...

Thanks for supporting, shadowslair ! Having the cylinder and box volumes as an alternative at least for static objects will be nice- a tree trunk, a barrel or a street lamp base will be "cheaper" as a cylinder, and some boxes, small houses etc will be better for the box shape I've got your...

Wow, it's been a month since I've been in this topic! I did not have as much time for coding as I wanted. But the last two weeks I've been struggling to deal with some issues. The first and most important is, that I've decided to go for a simple character-collision system, and not a general one. Alt...

Hi cheshirekow, sorry for not responding but I'm being very busy these days. Thanks for the hints, I'll try them, and I think I'll make a small test app for it, that might help others. But only when I've got time.

Hi! I've got some problem with the code. Please note that this is only a quick-and-dirty conversion from your matlab script into cpp. I've tried the steepest descent method first. I've maximized the number of iterations, just in case, and it frequently hits the limit. Plus, no matter how many iterat...

Fascinating! I'm truly impressed. Thank you for the time and effort! Everything seems to be very well explained. Now I'm going to read the whole article in detail.

Cheers,

Okay, I start to feel sick about ellipsoids right now. I can see nothing else but ellipsoids everywhere... :shock: Thanks for the links, Dorth, the best choice seems to be the second one. It's a bit disappointing though that it talks about x iterations of solving the equations to find that silly poi...

@Dorth: :D I have some other shapes, if you're interested... But I know the solution for those. @JeroenP: You're right, see below! Yeah, but I need something faster than searching among many points. It'd depend on the "resolution" (amount of points), too. But for testing the solutions we'...

Hey but what if we'd combine it with SiO2's idea: - find a proportionally larger ellipsoid, that P actually lays on - if it lays on the ellipsoid, it's closest point is itself - since we've made our ellipsoid larger, it has new focus points, so - we can set up the P-F1, P-F2 lines now, get the middl...

Wow JeorenP, thanks! You're even providing source! However, I think I have to disappoint you. I've fallen into the same mistake maybe only a couple of minutes before you, while browsing for the answer and finding this page: http://www.mathopenref.com/ellipsetangent.html I've marked with red what you...

I think the weakest point of my approach is simply that I don't pick the right angle. The right angle would be perpendicular to the tangent.

Also, I can see that my solution could be greatly simplified.

I think I understand it, I'm gonna "test" it on paper. Thanks for the idea!

Thank you very much! I use C::B and MingW too. Downloading!

Sorry guys I didn't have as much spare time as yesterday. I really appreciate the effort you guys put into this! Thanks! @Dorth: Yes, see my approach below. (I've added your idea about the foci, thanks!) xray: Yeah, it does ring a bell, however, I'm not really familiar with derivates and integrates....
