Temporal Anti-Aliasing

In this chapter, we will expand on a concept touched on in the previous one when we talked about temporal reprojection. One of the most common ways to improve image quality is to sample more data (super-sampling) and filter it down to the needed sampling frequency.

The primary technique used in rendering is Multi-Sample Anti-Aliasing, or MSAA. Another technique used for super-sampling is temporal super-sampling or using the samples from two or more frames to reconstruct a higher-quality image.

In the Volumetric Fog technique, a similar approach is used to remove banding given by the low resolution of the Volume Texture in a very effective way. We will see how we can achieve better image quality using Temporal Anti-Aliasing ...
