Interface ILcdIntersectionMatrix

public interface ILcdIntersectionMatrix
This interface defines a dimensionally extended nine intersection matrix (DE-9IM). This 3x3 matrix stores information about the way two shapes are topologically related. More specifically, the rows (columns) correspond with the interior, boundary and exterior respectively of the first (second) shape. The row and column index are given as an ELcdGeometryRegion. Each matrix element contains the dimension of the intersection of the two corresponding regions.
