There have been significant advances in the use of meshfree approximants for the solution of partial
differential equations [26–34]. However, in spite of the maturity of meshfree methods, there are
currently no tools in the public-domain to visualize meshfree basis functions. We have developed
JAVA applets to visualize basis functions in one, two, and three dimensions; the two-dimensional
JAVA applet menu is shown in Figure 2. The applets serve as a suitable aid to readily discern the
similarities and distinctions between the different meshfree approximation schemes.
