Summary:

This program will map a circular image to the surface of a cone.  By folding the quarter circle image generated by the program into a cone shape and looking down on the point of the cone, the original image can be seen.  This makes a great challenge to your friends - give them the distorted image and challenge them to figure it out.  Tell them it is an IQ test that will make them think.  This program only uses the standard picture control, so it doesn't require any special modules or toolkits to run.  It works best with high resolution images.  Low resolution images become a little blocky during resampling.

Function:

The program loads the image as a 2D array.  The mapping loops through each coordinate in the destination image and finds the matching coordinate in the original image, then copies that pixel value.  The end result is another 2D array which can be saved as an image.  The distorted image is a quarter circle which must be printed, cut out, and folded to construct the cone.

Steps to execute code:

1. Run Cone Mapping Main.vi
2. Press Load button and select image to be mapped.
   
3. Adjust Zoom Out factor so entire image can be seen.
4. Adjust Circle settings so circle contains portion of image to be mapped to cone.  The angle determines where the circle is cut for the cone.
5. Press Map button to generate the new image.
6. Adjust Zoom Out factor so entire mapped image can be seen.
7. If it looks good, press the Save button to save the image to disk for printing or distribution.
