Abstract—Real-time evaluation of distributed contact forces between rigid or deformable 3D objects is a key ingredient of 6-DoF These behave in a similar fashion to the translational properties, but the main difference is in the velocity-momentum In physics, a rigid body (also known as a rigid object) is a solid body in which deformation is zero or so small it can be neglected 1: A rigid-body is rotating around an origin point with a fixed rate The angular velocity (according to Wikipedia [1], it should be an orbital angular velocity) is a 3-vector whose direction is prependicular to the rotation plane and magnitude is the rate of rotation , and it responds to forces through f=ma Rigid bodies also add properties of rotation 1 Orthogonal Transformations There are two ways of thinking
