Rotational Swirl
- Solid rotation in circle
- Opposite rotational fields in circle, hi-res
- Opposite rotational fields in circle, lo-res
- Opposite solid rotations in circle
- Ellipse in rotational field, hi-res
- Ellipse in rotational field, lo-res
Squashed Circle
- Single boundary, no interior generators
- Internal boundary, no interior generators
- Single boundary, 2 interior generators
Current Issues
Identified problems with vtkDelaunay2D that sometimes generates non-Delaunay edges:
