template struct mola::index3d_hash

Overview

This implement the optimized hash from this paper:

Teschner, M., Heidelberger, B., Müller, M., Pomerantes, D., & Gross, M. H. (2003, November). Optimized spatial hashing for collision detection of deformable objects. In Vmv (Vol. 3, pp. 47-54).

#include <index3d_t.h>

template <typename cell_coord_t = int32_t>
struct index3d_hash
{
    // methods

    std::size_t operator () (const index3d_t<cell_coord_t>& k) const;
    bool operator () (const index3d_t<cell_coord_t>& k1, const index3d_t<cell_coord_t>& k2) const;
};

Methods

std::size_t operator () (const index3d_t<cell_coord_t>& k) const

Hash operator for unordered maps:

bool operator () (const index3d_t<cell_coord_t>& k1, const index3d_t<cell_coord_t>& k2) const

k1 < k2? for std::map containers
