TGeoVoxelGrid< T, S > Class Template Reference

template<typename T, typename S = float>
class TGeoVoxelGrid< T, S >

A finite 3D grid structure, mapping/binning arbitrary 3D cartesian points onto discrete "voxels".

Each such voxel can store an object of type T. The precision of the voxel binning is done with S (float or double).
