Experimental comparison of splines using the shape-matching paradigm

There are a variety of spline formulations for specifying smooth curves. In theory, many of these are equivalent in terms of the families of curves that can be obtained. In practice, each formulation encourages the implementation of certain styles of interaction in a curve editor and discourages other styles. This paper presents the design, implementation, and analysis of four experiments to illustrate a general shape-matching paradigm for studying interactive curve manipulation.
