public BlinnMicrofacet()

Method Detail

sample

public double sample(MicroFacet mf,
                     double[] in,
                     double u,
                     double v,
                     double[] out,
                     double[] brdf)

Sample the given microfacet distribution.

Specified by:

sample in interface MicrofacetDistribution

Parameters:

mf - The MicroFacet (point on surface of some solid).

in - Input direction (should look from the hit point).

u - Random uniform number.

v - Random uniform numbers.

out - Output direction in world coordinates.

brdf - Color definition - double[C] array (C can be either 1 /for monochrome computing/, 3 /for RGB color system/ or greater /for more complex spectral color sampling/).

Returns:

Probability density function.

pdf

public double pdf(double[] in,
                  double[] out)

out - Output direction in local coordinates.

D

public double D(double[] half)

Return a microfacet distribution term.

Specified by:

D in interface MicrofacetDistribution

Parameters:

half - Half-vector in local coordinates.

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.
