Fast Hierarchical Culling | cesium.comAs part of adding streaming 3D buildings to Cesium, we implemented some interesting view frustum culling optimizations for bounding volume hierarchies (BVHs). In particular, we implemented plane masking as described by Sýkora & Jelínek in Efficient View Frustum Culling (Section 2.5). In this article, we explain the algorithm, including pseudocode, and share performance results. Overview Generally,
