				<div class="class-description"><p>An octree is a hierarchical tree data structure used to partition a three-dimensional
space by recursively subdividing it into eight octants.</p>
<p>This particular implementation can have up to sixteen levels and stores up to eight triangles
in leaf nodes.</p>
<p><code>Octree</code> can be used in games to compute collision between the game world and colliders from
the player or other dynamic 3D objects.</p></div>
