object to represent cell connectivity
Definition: vtkCellArray.h:181
Fill all 2D contours to create polygons.
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
static vtkContourTriangulator * New()
static int TriangulateContours(vtkPolyData *data, vtkIdType firstLine, vtkIdType numLines, vtkCellArray *outputPolys, const double normal[3])
Given some closed contour lines, create a triangle mesh that fills those lines.
static int TriangulatePolygon(vtkIdList *polygon, vtkPoints *points, vtkCellArray *triangles)
A robust method for triangulating a polygon.
