Is there a mathematical method that takes a matrix and generates a "diamond" of values from rotating it 45 degrees?

Asked by HeroicZach (195points) November 29th, 2010

I’m writing a program that simulates a game, and to do so I need to come up with a function that can rotate a matrix by 45 degrees, essentially. So if I have a 5 by 5 matrix, I need to generate a list of lists looking like:
4,1 5,2
3,1 4,2 5,3
etc etc all the way down to 1,5

I’m wondering how an operation like this would work…thanks!

Do you have to show this matrix to the user? Because if you don’t then you don’t need to tilt it.

I am not sure what you mean by roatate 45 degrees. How does (4,1) end up next to (5,5)? If I knew what you wanted to do, I might be able to provide an alogorithm for transforming the matrix.

Are you talking about spatial anti-aliasing techniques?
