WebAs the octree structure is discrete and non-differentiable, it is non-trivial to directly employ octree in a learning-based framework. We propose a novel hierarchical network that recursively encodes and decodes both octree structure and geometry features in a differentiable manner. Specifically, at the Web4 de ago. de 2015 · Fast Hierarchical Culling. Kai Ninomiya August 4, 2015. As part of adding streaming 3D buildings to Cesium, we implemented some interesting view frustum culling optimizations for bounding volume hierarchies (BVHs).

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.
