Method Detail

getSample

public long getSample(double x,
                      double y,
                      int order,
                      int total,
                      double[] color)

Computes one image sample. Passes parameters for hidden sampling.

Specified by:

getSample in interface ImageFunction

Overrides:

getSample in class DefaultImageFunction

Parameters:

x - X coordinate of the sample.

y - Y coordinate of the sample.

order - Order of this sample inside the actual pixel.

total - Total number of samples in the actual pixel.

color - Pre-allocated array to hold result color vector (double[1] for monochrome images, double[3] for RGB images, larger arrays can be used for more complex spectral sampling).

Returns:

Hash-value (sample signature) used for adaptive subsampling.

See Also:

DefaultImageFunction.getSample(double,double,double[]), DefaultImageFunction.getBounds(double[])

set

public void set(java.lang.String key,
                java.lang.Object value)

Sets the given property.

Specified by:

set in interface Property

Overrides:

set in class DefaultProperty

Parameters:

key - Key string.

value - The new value.

See Also:

Property.commit()

get

public java.lang.Object get(java.lang.String key)

Gets the given property.

Specified by:

get in interface Property

Overrides:

get in class DefaultProperty

Parameters:

key - Key string.

Returns:

The actual value or null.

setTemplate

public static int setTemplate(Template t,
                              int ord)

General-purpose registration routine. Sets all plugs, strings, etc. to the given Template.
