Method Detail

monoBSSRDF

public double monoBSSRDF(boolean worldCoords,
                         double[] in,
                         double[] out,
                         double[] normal,
                         double[] tangent,
                         int mask)

Returns the requested BSSRDF sample (BSSRDF is treated as monochrome).

Specified by:

monoBSSRDF in interface BSSRDF

Overrides:

monoBSSRDF in class LambertianModel

Parameters:

worldCoords - Should be set to true if vectors in and out are in world coordinates and to false if vectors in and out are in local coordinates.

in - Input ray direction (double[3] or double[4]).

out - Output (viewing) ray direction (double[3] or double[4]).

normal - Normal vector of a surface.

tangent - Tangent vector of a surface.

mask - Which light components are to be computed?

Returns:

BSSRDF coefficient f(in->out).

colorBSSRDF

public double[] colorBSSRDF(boolean worldCoords,
                            double[] in,
                            double[] out,
                            double[] normal,
                            double[] tangent,
                            int mask,
                            double[] result)

Returns the requested BSSRDF sample (BSSRDF is treated as band-color).

Specified by:

colorBSSRDF in interface BSSRDF

Overrides:

colorBSSRDF in class LambertianModel

Parameters:

worldCoords - Should be set to true if vectors in and out are in world coordinates and to false if vectors in and out are in local coordinates.

in - Input ray direction (double[3] or double[4]).

out - Output (viewing) ray direction (double[3] or double[4]).

normal - Normal vector of a surface.

tangent - Tangent vector of a surface.

mask - Which light components are to be computed?

result - Pre-allocated double[C] array to hold BRDF coefficients f(in->out) (C can be either 1 /for monochrome computing/, 3 /for RGB color system/ or greater /for more complex spectral color sampling/). Can be null.

Returns:

Output BSSRDF spectral coefficients.
