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.

Description of buttons


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
