Represents a 3D Hash Grid structure used for spatial partitioning of points in 3D space. This structure organizes points into grid-based cells, enabling efficient spatial querying and insertion operations.
The radius used to determine proximity checks within the grid. Points are considered neighbors if their spatial distance is less than or equal to this radius.
Represents the total number of points currently stored in the hash grid. This property is incremented whenever a new point is inserted into the grid. It's read-only for external access and cannot be modified outside the class.
