Reflections and Collisions In the programming assignment, when a rigid body traveling at velocity vector d 14 1 point collides with an object, its velocity will be changed to the reflected vector r. If a rigid body hits the ground and needs to bounce upwards, how should you Consider the following diagram of the situation that occurs when the ball hits the compute the reflected velocity? ground. For additional explanation, please also see the documentation for Assignment 2. r=(d.x,d.y,d.z)r=(d.x,d.y,d.z)r=(d.x,d.y,d.z)r=(d.x,d.y,d.z)r=(d.x,d.y,d.z) 151 point Now consider the case where a rigid body hits one of the vertical walls on the left or right side of the play area. How should you compute the reflected velocity? r=(d.x,d.y,d.z)r=(d.x,d.y,d.z)r=(d.x,d.y,d.z)r=(d.x,d.y,d.z)r=(d.x,d.y,d.z)
