"WebSphere-Octree. When creating a sphere-octree node, it receives a bounding box and then creates a bounding sphere which includes all faces that are part of the bounding box. In this program, a face can be part of more bounding boxes when the different vertices are in different bounding boxes. The sphere is defined by an origin and a radius. " - Hierarchical octree

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.
