Lecture 3: Sampling, Aliasing, Antialiasing (5)

The latest generation of NVIDIA graphics cards include hardware-supported ray-tracing, which can dramatically improve the time it takes to render a scene using realistic lighting effects. See more: https://developer.nvidia.com/rtx/raytracing


Ray tracing is an instance of an image-ordered rendering technique, meaning that it works from the pixels on the screen, to objects in a scene, and finally to light sources to determine pixel color values. This would be more efficient for rendering complex scenes than determining which rays emitted by a light source eventually come in contact with the screen i.e. Object-ordered rendering. https://en.wikipedia.org/wiki/Image_and_object_order_rendering
