Sampling

Sample Transformations Zoo

We present several formulas and methods for generating samples distributed according to a desired probability density function on a specific domain. Sampling is a fundamental operation in modern rendering, both at runtime and in preprocessing. It is …

Generating Stratified Random Lines in a Square

When generating a set of uniformly distributed lines through a square, some care is needed to avoid bias in line orientation and position. We present a compact algorithm to generate unbiased uniformly distributed lines from a uniform point set over …
