Super Sampling
A form of uniform post-filtering used to fix aliasing issues.
Render a virtual image at n times resolution and then filter from this larger image.
For SSAA we render onto a larger buffer and then for each pixel in screen space, we find the corresponding [see page 19, region] in the buffer and use a convolutional filter to determine the color for the given pixel.
Adaptive Super Sampling
[see page 24, Uses] more sub-pixel samples around the edges of an object.
