示例1: intersect

double tmin, tmax;
if (hasBoundingBoxCapability() && !(bounds.intersect(r, tmin, tmax))) return false;
// Transform the ray into the object's local coordinate space
Vec3d pos = transform->globalToLocalCoords(r.getPosition());
Vec3d dir = transform->globalToLocalCoords(r.getPosition() + r.getDirection()) - pos;
double length = dir.length();
dir /= length;
