Planar view — the rational curve in the 2D plane

Homogeneous view — the curve in homogeneous 3D coordinates, along with its projection onto the 2D plane

Planar view: drag control points to move them. Homogeneous view: drag a homogeneous control point along its dashed ray to change its weight, or drag the background to move the camera.
