WebUse the Rigid Body Contact node () to model structural contact between rigid bodies. In the contacting bodies, the source must be always a rigid sphere (3D) or a rigid circle (2D). The destination can be of two types; either a rigid sphere (or circle) or of arbitrary shape. If friction is to be included, add a Friction (Rigid Body Contact) subnode.
