WebBounding Volume Hierarchy. We will build our approach around a bounding volume hierarchy (BVH), which is a commonly used acceleration structure in ray tracing (for example). A bounding volume hierarchy is essentially a hierarchical grouping of 3D objects, where each group is associated with a conservative bounding box. WebPointNet++ learns hierarchical features with increasing scales of contexts, just like that in convolutional neural networks. Besides, we also observe one challenge that is not …
