Spin User Guide

The Spin component of Axom provides several index data structures to accelerate spatial queries. The Morton code classes relate each point in a region of interest to a point on a one-dimensional space filling curve, and the RectangularLattice helps in the computation of bin coordinates. The UniformGrid and ImplicitGrid classes build one-level indexes of non-intersecting bins, while the BVHTree and SpatialOctree classes build nesting hierarchies of bounding boxes indexing a region of interest.
