title: Bicubic Interpolation?
body: <p>I looked through the internet, and in terms of Bicubic Interpolation, I can't find a simple equation for it. Wikipedia's page on the subject wasn't very helpful, so is there any easy method to learning how Bicubic Interpolation works and how to implement it? I'm using it to generate Perlin Noise, but using bilinear interpolation is way to choppy for my needs (I already tried it).</p>
  
  <p>If anyone can point me in the right direction by either a good website or just an answer, I would greatly appreciate it. (I'm using C# by the way)</p>
