Arrow Field Tool
This tool plots evenly spaced arrows on an image. The magnitude and direction of the arrows are given by two other images of the same dimensions.
Example:Viewing simulated stress in concrete Example
This tool uses three images. Loading
instructions for the images, which are in ASCII format.
Two of the images contain the magnitude and direction (radians) of the stress
vectors. The third image is a structure map of the sample. The tool uses the
first two images to draw stress arrows on the third image
