Method Detail

adjustOrientation

static void adjustOrientation(Triangulator triRef,
                              int i1,
                              int i2)

determine the outer polygon and the orientation of the polygons; the default orientation is CCW for the outer-most polygon, and CW for the inner polygons. the polygonal loops are referenced by loops[i1,..,i2-1].

polygonArea

static double polygonArea(Triangulator triRef,
                          int ind)

This function computes twice the signed area of a simple closed polygon.

determineOrientation

static void determineOrientation(Triangulator triRef,
                                 int ind)

Determine the orientation of the polygon. The default orientation is CCW.
