Summary	0028372: Foundation Classes - BVH_Tree class refactoring
Description	As discovered during review of fix for 0028368, current implementation of class BVH_Tree is confusing: 1. Structures BVH_BinaryTree (and BVH_QuadTree) and class BVH_TreeBase are defined not in the same-named headers but in BVH_Tree.hxx. This looks illogical. Note that in OCCT we have convention that a class should notmally be defined within the same-name header. 2. The names like BVH_Tree and BVH_BinaryTree are suggesting that the latter is successor of the former. This is not the case. Instead, BVH_Tree is dummy that has two specializations, while BVH_BinaryTree and BVH_QuadTree are just tags used to trigger specializations. It seems to be more straightforward just to define class BVH_Tree (or BVH_TreeBase) and two descendants, BVH_BinaryTree and BVH_QuadTree, providing relevant specializations.
Tags	No tags attached.

~~abv~~ 2019-09-05 21:12 manager ~0086820	Is that issue still relevant after #30655?

~~emv~~ 2019-09-06 07:08 developer ~0086826 Last edited: 2019-09-06 07:08	The issue is still relevant. The intent of #0030655 was to provide interfaces for simple usage of BVH tree, not its refactoring.
