Constructs a hexahedral mesh topology from a dense 3D grid
The resulting hexes will be indexed following usual convention assuming that z is the fastest moving index direction
(counter-clockwise bottom vertices, then counter-clockwise top vertices)
- Parameters:
Nx (int) – Resolution of the grid along x dimension
Ny (int) – Resolution of the grid along y dimension
Nz (int) – Resolution of the grid along z dimension
- Returns:
Array of shape (Nx * Ny * Nz, 8) containing vertex indices for each hexahedron
