Introduction to raytracing

Hello,

In our theory presentation about light and lightning representations, we will introduce and detail several techniques for modeling and rendering light. One of the most important is the ray tracing technique, which is used to compute a 2D image as the perception of a 3D modeled scene from a virtual viewer.
Here is a basic introduction to the theory of ray tracing in practice:

This webpage presents the basic ideas behind the implementation of ray tracing and the different situations that have to be dealt with in order to create an accurate rendering of a scene.
During our presentation, we will explain in more details the theory of this method and its implementation.
