Standard tissue initialization

Rectangular grid

The RectangularGrid class enables users to create regular grids of cell bodies based on the dimension of the tissue and the spacing between cells. As an example, the figure obtained was captured for a tissue with the same size but different spacing values.

Hexagonal grid

The HexagonalGrid class also creates structured grids, but cells are shifted to the side on each row, so that the projection of a cell on the following row is placed between two cells. The size and spacing of the grid can be defined by the user.
