Expand description
Trait of bounding volumes.
Bounding volumes are coarse approximations of shapes. It usually have constant time intersection, inclusion test. Two bounding volume must also be mergeable into a bigger bounding volume.
Required methods
Returns a point inside of this bounding volume. This is ideally its center.
fn intersects(&self, _: &Self) -> bool
fn intersects(&self, _: &Self) -> bool
Checks if this bounding volume intersect with another one.
Merges this bounding volume with another one. The merge is done in-place.
