Member Function Documentation

void voro::container_poly::clear ( )

Clears a container of particles, also clearing resetting the maximum radius to zero.

Definition at line 390 of file container.cc.

void voro::container_poly::compute_all_cells ( )

Computes all of the Voronoi cells in the container, but does nothing with the output. It is useful for measuring the pure computation time of the Voronoi algorithm, without any additional calculations such as volume evaluation or cell output.

Definition at line 446 of file container.cc.

template<class v_cell , class c_loop >
bool voro::container_poly::compute_cell ( v_cell &  c,
c_loop &  vl 
) [inline]

Computes the Voronoi cell for a particle currently being referenced by a loop class.

Parameters:
[out]ca Voronoi cell class in which to store the computed cell.
[in]vlthe loop class to use.
Returns:
True if the cell was computed. If the cell cannot be computed, if it is removed entirely by a wall or boundary condition, then the routine returns false.

Definition at line 664 of file container.hh.

template<class v_cell >
bool voro::container_poly::compute_cell ( v_cell &  c,

Parameters:
[out]ca Voronoi cell class in which to store the computed cell.
[in]ijkthe block that the particle is within.
