public BumpMap(RenderedImage texture,
       double surfaceScale,
       double scaleX,
       double scaleY)

Stores the normals for this bumpMap. scaleX and scaleY are the user space to device space scales.

Method Detail

getSurfaceScale

public double getSurfaceScale()

Returns:

surface scale used by this bump map.

getNormalArray

public double[][][] getNormalArray(int x,
                          int y,
                          int w,
                          int h)

Parameters:

x - x-axis coordinate for which the normal is computed

y - y-axis coordinate for which the normal is computed
