octree levels api #2

Closed stefanmaierhofer closed 5 years ago

stefanmaierhofer commented 6 years ago

Currently the following functions operate on relative tree depths (starting from root):

CountPointsInOctreeLevel(int level)
QueryPointsInOctreeLevel(int level),
GetMaxOctreeLevelWithLessThanGivenPointCount(long maxPointCount)

Changing this to absolute values based on cell size (2^exponent) would enable various improvements:

values become associated with absolute scale, which is immediately understandable without context
values become consistent across multiple octrees
values become directly applicable/compatible with query functions taking an optional traversal depth limit, which is already specified as 2^exponent
