ode for 2d simulation

Although I'm not sure if they did some work on it for ODE 0.6, you could use Plane2D. It's a major pain to use, unfortunately.

Thanks for your reply! I'm using ODE 0.6 and for my understanding Plane2D only works for ODE 0.039 (or older versions). Is there any other (simple) way to make 2D simulations possible? I guess the "sandwich" approach would work but isn't very stable, or am I misstaken?

Google helped me dig up this. It was in these forums not too long ago, but finding things like that can be a little tedious at times. I'm not too sure about the licensing, but the engine itself doesn't look too bad.

Thanks! I will look in to it!

I got Plane2d working on ODE 0.6, once I fixed the compile errors it worked fine ;) (Took about an hour).

Plane2d isn't really that much harder to use them any other joint, it is just a pain to "install" as you have to integrate it directly with the source code.

The biggest thing was I hacked in the dVector3 stuff:

dVector3 mVec;    if (joint->row_motor_x > 0)	{		mVec[0]=Midentity[0][0];		mVec[1]=Midentity[0][1];		mVec[2]=Midentity[0][2];		joint->motor_x.addLimot(joint, info, joint->row_motor_x, mVec, 0);	}    if (joint->row_motor_y > 0)	{		mVec[0]=Midentity[1][0];		mVec[1]=Midentity[1][1];		mVec[2]=Midentity[1][2];        joint->motor_y.addLimot(joint, info, joint->row_motor_y, mVec, 0);	}    if (joint->row_motor_angle > 0)	{		mVec[0]=Midentity[2][0];		mVec[1]=Midentity[2][1];		mVec[2]=Midentity[2][2];        joint->motor_angle.addLimot (joint, info, joint->row_motor_angle, mVec, 1);	}

It is really messy but I didn't know a better way to convert the Identity matrix to a dReal3 :P. If anyone knows of a way then that would be great ;).

Thanks! I will try that later on today. Is it possible for you to send me the files that need to be modified?
