In order to produce Ray Traced images, we follow the basic ray tracing algorithm, as follows: for (each pixel (sample) on the viewing area) { for (each primitive in the world model) { if (ray-pixel intersection) { select the frontmost intersection; recursively trace the relection and refraction rays; calculate color; } } }

c,z. c) and radius R can be represented as: (x-x. c) + (y-y. c) + (z-z. c) - R = 0 For a point pon the sphere, we can write the above in vector form: (p-c). (p-c) - R = 0 (note ‘.’ is a dot product) We can plug the point on the ray p(t) = e+ t d. (e+td-c). (e+td-c) - R = 0 and yield (d.d) t + 2d.

Okay, a few comments on this. First it should be noted that all the colors inside our code will be treated as three components floating point numbers. We ...
