Thanks, Fabrice, but I understand as much.
In particular I am trying to understand this function
public function intersects(other:MeshObject):Boolean {
// Use up to 6 separating planes
if ( this.model.maxX + this.model.x < other.model.minX +
other.model.x ) return false;
if ( this.model.maxY + this.model.y < other.model.minY +
other.model.y ) return false;
if ( this.model.maxZ + this.model.z < other.model.minZ +
other.model.z ) return false;
if ( this.model.minX + this.model.x > other.model.maxX +
other.model.x ) return false;
if ( this.model.minY + this.model.y > other.model.maxY +
other.model.y ) return false;
if ( this.model.minZ + this.model.z > other.model.maxZ +
other.model.z) return false;
// otherwise, must be intersecting
return true;
}
Which should be testing the intersection of two objects.
Thanks.
