The ray-tracing algorithm takes an image made of pixels. For each pixel in the image, it shoots a primary ray into the scene. The direction of that primary ray is obtained by tracing a line from the eye to the center of that pixel.

ANSWER: the reader is correct. An eye is not a point receptor, but a surface receptor-like the film or CCD in your camera. Because this lesson is just an introduction to the ray-tracing algorithm, this topic is too complex to be explained in detail. Both cameras and the human eye have a lens that focuses reflected light rays onto a surface ...

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.

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; } } }

Full Ray-Tracing • For each pixel – Compute ray direction – Find closest surface – For each light • Shoot shadow ray • If not shadowed, add direct illumination – Shoot ray in reflection direction – Shoot ray in refraction direction
