Detailed Description

Base class for raytracers, containinng basic functionality needed for implementing various raytracing algorithms (Whitted, Pathtracing).

When the function computeImage() is called, the image is raytraced by calling tracePixel() for each pixel in the output image. A very basic implementation of tracePixel is provided, but to implement more advanced algorithms (Whitted, Pathtracing), the tracePixel() function should be overridden in a sub class.
