PPT-How to implement simple collision detection

What you will learn today How do we know if these have collided Sphere Collisions Distance Sphere Collisions More precisely if length sphereApos sphereBPos lt radiusA . Assuming all the particles started out above the 711oor theyd all have to stay there for the rest of the simulation How could we go about implementing this Clearly there are two problems We need to detect when particles are near the 711oor and when Generic . b. irthday attack.
