ABSTRACT:
A graphic technique, implemented on a graphics computer, for visualizing 3-D vector data uses a stream tube which is a tube-like structure having a cross section of an n-sided polygon. The stream tube follows the path of a streamline in the 3-D vector data. Data can be visualized by varying the shape and size of the polygon along the streamline to represent changes in normal and shear strain, rotation and velocity. Additional scalar functions are represented by coloring the sides of the stream tube.
