Ray Tracing Essentials Part 2: Rasterization versus Ray Tracing

In Part 2: Basics of Ray Tracing, NVIDIA's Eric Haines runs through the basics of rasterization and ray tracing. For decades, rasterization, also known as the Z-buffer, has been the method of choice for rendering 3D images at interactive rates. This talk contrasts and compares it with ray tracing, showing how the operations have a certain symmetry.
