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! 10/24/17 CSU CS 410 Fall 2017 ©Ross Beveridge & Bruce Draper 13

– 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 Geometric transformations – the inverse transformation is applied to the ray

Recursive-Ray-Tracer Implementation of a Ray-Tracer for Rendering in C++ carried out for the course of Computer Graphics at Saarland University taught by Prof. Philipp Slusallek . The goal of the project was to implement Ray-Tracing without using any Rendering Library for a developing a deeper understanding of Rendering concepts. Example Output:
Ray tracing (graphics) - Wikipedia
https://en.wikipedia.org/wiki/Ray_tracing_(graphics)
The idea behind ray casting, the predecessor to recursive ray tracing, is to trace rays from the eye, one per pixel, and find the closest object blocking the path of that ray. Think of an image as a screen-door, with each square in the screen being a pixel. This is then the object the eye sees through that pixel.

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.

Each point on an illuminated area, or object, radiates (reflects) light rays in every direction. Only one ray from each point strikes the eye perpendicularly and can therefore be seen. Our eyes are made of photoreceptors that convert the light into neural signals.

We'll call these flows “light rays.” wLight rays travel in straight lines in free space. wLight rays do not interfere with each other as they cross. wLight rays obey the laws of reflection and refraction. wLight rays travel from the light sources to the eye, but the physics is invariant under path reversal (reciprocity). 4 Eye vs. light ray tracing
