Refraction occurs at each surface. The am ount of ray deviation depends on the surface power and the ray height. Transfer occurs between surfaces. The ray height change depends on the ray angle and the spacing between surfaces. The image location is found by solving fo r a ray height of zero in image space. yy j 1 jjj

In 1980, Turner Whittedintroduced ray tracing to the graphics community. wCombines eye ray tracing + rays to light wRecursively traces rays Algorithm: 1.For each pixel, trace a primary ray in directionVto the first visible surface. 2.For each intersection, trace secondary rays: wShadow raysin directions L ito light sources wReflected rayin ...

Ray Tracing: intersection and shading

Ray: a half line • Standard representation: point p and direction d – this is a parametric equation for the line – lets us directly generate the points on the line – if we restrict to t > 0 then we have a ray – note replacing d with ad doesn’t change ray (a > 0) 3

A ray is defined by an origin P and a unit direction d and is parameterized by t: P + td Let I(P, d) be the intensity seen along that ray. Then: I(P, d) = I direct + I reflected + I transmitted where I direct is computed from the Phong model I reflected = k r I (Q, R) I transmitted = k t I (Q, T) Typically, we set k r = k s and k t = 1 – k s.

POV-Ray - The Persistence of Vision Raytracer
David K. Buck - the creator of DKBTrace, the pioneering raytracer that was the genesis of POV-Ray - has created a KickStarter campaign to fund creation of an open-source IDE for PigeonTalk (PigeonTalk is a smalltalk implementation created by David that is aimed at being a programming environment to explore computing). "I chose Smalltalk as a language because it provides the …
