An octree is an object that represents a spacial partitioning. It is made up by a tree data structure in which each node has exactly eight children. Occupied leaf nodes are represented as voxels. Octrees can be used to offer a simplified representation for shapes or point clouds, or can act as an occupancy grid/space:


Octrees are collidable, measurable and detectable objects. This means that octrees:

  • can be used in collision detections with other collidable objects.
  • can be used in minimum distance calculations with other measurable objects.
  • can be detected by proximity sensors.
  • Octrees can be added to the scene with [Menu bar --> Add --> Octree], and edited via the octree properties.
