Ray Tracing: Fundamentals

This lecture introduces the fundamentals of ray tracing, starting with the generation of rays through pixels and their intersection with geometric primitives like spheres and planes. The instructor explains the implicit equations used to represent shapes, the process of solving quadratic equations for ray-sphere intersections, and the calculation of distances to planes. The lecture also touches on more complex shapes like cylinders and challenges students to explore torus intersections. By the end, students will have a basic understanding of how to implement a ray tracer and look forward to enhancing their images with lighting effects in the next session.
