Abstract
Methods, computer program products and systems for manipulating a spline are described. A spline can be displayed. A tangent bar that is tangent to a point on the spline and/or a curvature bar at the point can be displayed. A user input can be received defining one or more constraints on at least one of the tangent bar or the curvature bar, and the shape of the spline can be modified based on the one or more constraints.
