SpatialGrid
The SpatialGrid class provides a framework for managing and processing spatial data using a grid-based approach. It supports efficient creation, dispatch, and manipulation of the spatial grid, utilizing radix sorting and customizable dispatch operations. With its methods for grid creation, dispatching grid generation, and managing the spatial elements, the class is well-suited for applications that require fast, scalable spatial partitioning and computation, such as in graphics rendering, simulations, and physics-based applications.
