Hierarchical octree

WebAn overview of hierarchical data structures for representing images, such as the quadtree and octree, is presented. They are based on the principle of recursive … WebThe process of hierarchical frustum culling is rather simple. A set of planes is generated that define the frusum (usually six planes, including hither & yon.) The Octree is traversed, and each node along the traversal is tested against an intersection with the view volume. From this test, one of three states is determined: 1.
