Description: Figure 5.4: Interactive simulator of 2D Fourier synthesis. Change the horizontal ( \(u\) ) and vertical ( \(v\) ) position of the coefficient in the centered frequency spectrum and observe how the distance from the center dictates the spatial frequency (thickness) and the angle dictates the orientation of the generated sine wave.
