For elementary solids, intersectionscan be calculated. – start and end of ray traversal through a [convex] solid body. Set theoretic operations on all intersections along the ray. – distributive: P (A – B) = (P A) – (P B) – the usual ray-object intersection is a sequence of intervals.

Recursive Ray Tracing •Generalize ray trace –light from a ray –Ray leaves surface from point of intersection –In the direction of R V •And how does it compute illumination? •Exactly as we did it before, when … –Starting at the pixel –In the direction of V •So ray tracing is recursive!

tracing light rays from the scene back to the eye. Below is the basic ray tracing algorithm. Ray Tracing Algorithm For each pixel: i. Find all the intersections of the ray from the eye to the pixel with every object in the scene. ii. Keep the intersection closest to the eye. iii. Compute the color and intensity of the light at this intersection point.

Tracing Recursive Methods ¶ In Java the call stack keeps track of the methods that you have called since the main method executes. A stack is a way of organizing data that adds and removes items only from the top of the stack. An example is a stack of cups. You can grap a cup from the top of the stack or add more cups at the top of the stack.

Simply because this algorithm is the most straightforward way of simulating the physical phenomena that cause objects to be visible. For that reason, we believe ray-tracing is the best choice, among other techniques, when writing a program that creates simple images. To start, we will lay the foundation with the ray-tracing algorithm.

8.1.2 Recursive Ray Tracing. Basic ray casting can be used to compute OpenGL-style rendering and, with the addition of shadow rays, to implement shadows as well. More features can be implemented by casting a few more rays. The improved algorithm is called ray tracing. Consider specular reflection. In OpenGL, specular reflection can make an object look shiny in the sense …
