Bullet(s of) Physics

This video shows the Bullet Physics engine in action (obviously, in full Augmented Reality ;). I have used some of the demos you can found in the SDK. The interaction is made using the hand.

What library you used for AR? And how did you implement the hand tracking? It looks like a reaction to the marker being blocked.

@marsrendezvous Hi, i developed my own C++ AR library. The hand tracking was based on a simply pixel classifier.

Well, dont remember exactly what i done. First, you have to setup the matrix proj correctly. Second, you need to set the correct modelview matrix at every frame. My modelview matrix was obtained tracking a 2D marker. You have to setup the matrix at the top of the Opengl matrix stack...I update the camera in the renderme() method you can find in the DemoApplication.cpp file. Hope this helps!

@FrontierVision Ok. Thanks for the answer.

Great ! Now I use Bullet Physics in Augmented reality too.But I have a problem in collision detection between triangle mesh(collision object). When 2 collision objects hit each other, rotation and translation not correct. So could you please suggest me or can you describe me about your collision code.

Thanks,
