Detailed Description

A basic sample filtering class that warps samples to match a distribution.

In contrast to simply returning the weight of a given sample based on the filter values, Filters in galileo warp samples to have density proportional to the filter's kernel. This allows us to have all samples equally weighted, with more samples in areas of higher filter importance.

Member Function Documentation

virtual void Filter::filter (  Vector2 *  samples, int  num_samples )  const [pure virtual]

Warp the array of samples in place. Parameters: [in,out]  samples  The array of samples to be warped. [in]  num_samples  The number of samples in the array. Returns: The samples will be warped according to the filter kernel. Implemented in BoxFilter, CubicSplineFilter, and TentFilter.

virtual void Filter::filter (  Vector2 &  sample  )  [pure virtual]

Warp a single sample in place. Parameters: [in,out]  sample  The sample to be warped. Returns: The sample will be warped according to the filter kernel. Implemented in BoxFilter, CubicSplineFilter, and TentFilter.
