Unsigned collisiondetector sphere sphere

The fnal phase of our algorithm is to fnd the closest point i
point and generate the contact from it. We’ll do this frst in the
This is a simple process. All we need to do is to clamp each
point to the half-size of the box in the same direction. With
then work out the distance from the center of the sphere to th
if it is larger than the radius of the sphere. The code for this is simple:

Excerpt from src/collide_fine.cpp

dist = relCenter.x;
if (dist > box.halfSize.x) dist = box.halfSize.x; if (dist < -box.halfSize.x) dist = -box.halfSize.x; closestPt.x = dist;

dist = relCenter.y;
if (dist > box.halfSize.y) dist = box.halfSize.y; if (dist < -box.halfSize.y) dist = -box.halfSize.y; closestPt.y = dist;
