This program is mainly focused on calculating the volume of the removed material from a metal sheet due to Laser Beam exposure. All calculations are based on the height info recorded as a grayscale file in TIF/TIFF format. Data of these files are expected to be the output of the measurements made by a digital microscope.

SUMMARY

In order to accomplish the task, this program:

1)INPUT: Prompts user for a filename, pyhsical size of a bit and 4 seperate points. Filename is to access the file including height data. Size is for volume calculations and these points define the quadrilateral border(as being corners) of material removal site.

2)PROCESS 1: Discards the all ramining region beyond border. Line equations and matrix manipulations are done.

3)PROCESS 2: Again based on the 4 points, an approximate surface is defined based on linear approximations. The difference between the approximate surface and the actual surface. Volume above and below the approximate surface are calculated seperately. Approximate area and length of the region are calculated seperately

4)OUTPUT: Prints the "below volume", "above volume", "net volume change", "length of the region", "approximate area of the region", 3-D shape of selected region and approximate surface
