Incomplete octree on the GPU.
The incomplete octree specialisation for GPU is templated on a strategy type parameter, allowing the specialisation to be used with different incomplete tree implementations. The storage is necessarily compact, segmented by tree levels.
A baseline strategy is given: binary search segmented by levels.
The GPU tree has a different interface to the CPU tree - see class methods (sfcToLocal, etc)
Kernels for strategy functions required by the GPU tree specialisation are also provided.

Things to improve:

  • The CPU incomplete tree could be similarly templated on a strategy (current hash set implementation to be extracted).
