    Image Processing: Understanding DFT Basics

    I am trying to understand some really basics of image processing. One of them is the DFT ( Discrte Fourier Tranform). I have seen code segments, read stuff but still I don't get how the image produced is related to the first one. For example, I take an image with vertical black and white...

    Normalizing Vectors and Light in Computer Graphics

    I am trying to understand how light works in computer graphics. Especially OpenGL 3+. So I was given a paper that says how to calculate light. It says "normalise the vectors before taking the dot product".How do I normalize vectors and why? I have to compute the normals to a vertex. What is a...
