GDC 2007
Hello all!
I again participated at the GDC, giving a physics tutorial with Jim Van Verth, Christer Ericson, Squirrel Eiserloh, Gino van den Bergen, and Marq Singer. I changed my presentation a bit this year because I wanted to coordinate better with the other speakers and I wanted to discuss Jacobians and more constraint types. I have added only a couple of enhancements to Box2D at this time.
Download my presentation here. I hope you find it useful.

Hi. I downloaded your 2007 version of Box2D and made a few modifications to make it work under Mac OS X. But when I run the demo 4 for instance, all of the boxes fall through the floor. Any other demos that concern contact behave the same way.
Figuring I may have botched something in my few code changes, I downloaded your 2006 version of Box2D and made nearly the same modifications. In that version, the demos appear to work as intended, boxes stack, things don’t fall through one another.
I just wanted to inform you of what I saw in the 2007 version. Thank you very much for making Box2D and your presentations available.

I love your open source policy and decided to begin implementing your 2006 physics engine during this year’s GDC.
I’ve avoided 3d matrix math like the plauge and found your 2d matrix math an enjoyable introduction to the topic. I cut a bit of what I thought was fat, but now the pyramid of boxes is running slow and sliding. I can’t wait to dive into your 2007.

I use Codeblocks with mingw32, I made an OpenGl project and added everything.
I get the error:
’struct FeaturePair::::Edges’ invalid; an anonymous union can only have non-static data members.
This, on file Arbiter.h.
Programme looks very impressive!
