But now we have exactly the instant relative velocity: const Vector3r relativeVelocity = (de1.vel+de1.angVel.Cross(c1x)) - (de2.vel+de2.angVel.Cross(c2x)) ; const Real normalVelocity = geom.normal.Dot(relativeVelocity); const Vector3r shearVelocity = relativeVelocity-normalVelocity*geom.normal; No? What is "delta"?
