My First Raycaster

This is a SLOW raycaster for a 5*5*1 grid. You can edit the grid, its in [A]. Make sure [A] is 5*5 before running. (Go to 2nd+X-1, over to edit and select [A]) 0s don't show up, all other below 10 show up as they are. (You are at {1,1}, looking straight towards {5,5})

The raycaster works by doing a sweep in increments of 15 degrees to theta (your total view arc is 90) and then in increments of 1 to R, then converts to XY and checks to see whats there.

The upper right box shows [A], the upper left shows the rays as they are cast and the bottom shows the actual view.

Note-This program sets your calc to degrees.
