Re: About utils.forcesOnPlane


Hello Vaclav, thanks for your answer, I think you mixed two normals (the one of the plane, and the one of the interaction) in your answer here :

The (dot1<0.?1.:-1.) only determines the sense from id1 to id2 based on the normal, and normal is always from id1 to id2.

But I think I've finally got it ! Thanks,
