Source tree structure

Overview of the directory tree of NanoVDB.

• NanoVDB.h C++11 implementation of the core data structure and its access methods.
• CNanoVDB.h Incomplete but useable C99 implementation of the core data structure and its access methods. Designed in particular for use in OpenCL kernels. Note that this relies on zero-sized arrays for the _reserved padding, so will not work on all compilers (with MSVC being a particular example)
• PNanoVDB.h C99 implementation of the core data structure and its access methods. More complete coverage than CNanoVDB. This version is pointer-less and supports virtually all graphics APIs.
• util/GridHandle.h defines a handler for the memory allocated to a NanoVDB grid.
• util/IO.h implements I/O support.
• util/OpenToNanoVDB.h defines the converter from OpenVDB to NanoVDB and obviously depends on the OpenVDB library (as the only header file).
• Ray.h Ray class.
• HDDA.h HDDA related.
• SampleFromVoxels.h interpolation.
