Method Detail

scatter

void scatter(IntersectionInfo intersection,
             ScatteredRayContainer scattered)

Given parameters describing the intersection of a ray with a surface, this will return the reflected and transmitted rays along with attenuation factors.

Parameters:

intersection - [in] information of the point of intersection

scattered - [in/out] container with the scattered rays

getRayColor

RGBColor getRayColor(IntersectionInfo intersection)

returns the color at intersection point

Parameters:

intersection - [in] information of the point of intersection

Returns:

the color at the intersection
