  +--jigl.image.ComplexMIPMap

public class ComplexMIPMap

extends Object

A MIPMap variation that stores sub-images reduced by the nth root of 2 each time. Gaussian noise is added to the image to get each sub-image.

Constructor Detail

ComplexMIPMap

public ComplexMIPMap(RealColorImage image,
                     int n)

image must be square and a power of 2 in size

Parameters:

image - RealColorImage to be used as the highest resolution image in the MIPMap.

n - image is reduced by the nth root of 2 for each sub-image.

Method Detail

get

public float[] get(float x,
                   float y,
                   float reduction)

Returns the pixel value at (x,y) of the reduced image.

Parameters:

x - x value

y - y value

reduction - reduction amount of image (2.0 would return the point at the image reduced by 1/2). must be >= 1.

getImage

public RealColorImage getImage(float reduction)

Returns an image at reduction. Faster than calling get for each pixel.

Parameters:

reduction - reduction amount of image (2.0 would return the image reduced by 1/2). Must be >= 1.
