Module arendur::sample [−] [src]

The sampling and filtering interface

Modules

distribution	Defines 1d and 2d distributions
filters	Defines some commonly used filters
naive	A naive sampler.
prelude
strata	Defines a stratified sampler

Filter	The filter interface. A filter always lies at $(0, 0)$ in its local frame.
Sampler	The sampling interface. Samplers should return sampled values in $[0, 1)$.
