IFAS: A Program to Measure Fractal Dimensions of Curves and Surfaces,

Abstract

The Interactive Fractal Analysis System (IFAS) allows the user to measure fractal dimensions of curves and surfaces. This is accomplished interactively through the use of virtual maps, character commands and responses, a graphic cursor, and an audible bell. With either a curve or surface, the user selects the most appropriate fractal dimension by entering a sampling interval and examining the generated scatterplot, correlation coefficient, and table. On a real-time basis, the user also has the capability of determining the fractal dimension for a portion of a curve or surface, editing features, windowing, and creating a perspective view of a surface. Several examples demonstrate that IFAS is able to closely approximate the fracticality of curves and surfaces. (Author)
