rocedure for Polyhedral Assembly Partitioning under In nitesimal Motions

We study the following problem: Given a collection A of polyhedral parts in 3D, determine whether there exists a subset S of the parts that can be moved as a rigid body by an in nitesimal translation and rotation, without colliding with the rest of the parts, A nS. A negative result implies that the object whose constituent parts are the collection A cannot… CONTINUE READING
