Method makeSpotLitDiffuse

shared/java/ImageFilter.java:937–945

Create a filter that calculates the diffuse illumination from a spot light source, using alpha channel of the input as the height profile of the surface (to approximate normal vectors). The spot light is restricted to be within 'cutoffAngle' of the vector between the location and target. @param x0

(float x0, float y0, float z0, float x1, float y1, float z1, float falloffExponent, float cutoffAngle, int lightColor, float surfaceScale, float kd, @Nullable ImageFilter input, @Nullable Rect crop)

     * @return                 filter that applies spot diffuse lighting
