functions at an arbitrary point within the convex hull. In 3D, basis function values on planes that
cut the convex hull are computed.
The visualization package is coded as a Java 1.4 applet and embedded in an HTML page that
detects screen resolution and adjusts the applet’s behaviour accordingly. The code is object-oriented
and hence modular, making it fairly easily extended. Visualizations resemble as closely as possible
the desirable styles of texts and journals, and software such as MathematicaTM and MatlabTM.
The generated visualizations are suitable for publication (EPS option in Figure 2). The capabilities
of the applet are demonstrated through basis function plots that appear in the ensuing sections.
