Method Detail

createImage

protected void createImage()

"helper function" to create an initial grid before the recursive function is called

displace

protected float displace(float width,
                         float height,
                         float num)

Randomly displaces color value for midpoint depending on size of grid piece.

divideGrid

protected void divideGrid(java.awt.Graphics g,
                          float x,
                          float y,
                          float width,
                          float height,
                          float a0,
                          float a1,
                          float a2,
                          float a3)

This is the recursive function that implements the random midpoint displacement algorithm (diamond square). It will call itself until the grid pieces become smaller than one pixel.
