randomColoration

public static VertexColoration randomColoration(Model m,
                                                Material[] sources,
                                                float threshold)

Constructs a semi-random VertexColoration for the given Model, using the given sources and threshold. This is supposed to produce a camoflage effect. It doesn't work too well, yet.

Parameters:

m - the Model.

sources - the array of Materials to use as the Materials that are randomly distributed for the Model.

threshold - the probability that a color other than the first one in the source array will be used. This allows the camoflage to be composed of a base color along with patches of other colors.

Returns:

the VertexColoration.

randomColoration

public static VertexColoration randomColoration(float[][] vertices,
                                                Material[] sources,
