Generalizing to Continuous Shape Parameters for Curves,he user to have more precise control over the shape of the curve. The user is no longer constrained to choose a unique value for each shape parameter over the entire curve. Now, different values of the shape parameters can be used to reflect the local character of the curve.

Classification and Analysis of Beta-spline Curve End Conditions,ions, as well as an analysis of their geometric properties, was previously presented by the author in . Analogous discussions for the Beta-spline curve and surface representations are presented in this section and Chapter 16, respectively.

Technology and the Human: Hans Jonasd prior to the actual computation of the Beta-spline basis functions. The following algorithm evaluates the basis functions at . + 1 given values of the domain parameter ., for a given value of each uniform shape parameter, β1 and β2, and requires 7 + 9(. + 1) multiplications, 12 + 2 + 9(. + 1) additions/subtractions, and 8 divisions.
