Detailed Description

Fractional wiener surface context.

1D case it is equivalent to fractional Brownian motion, for higher-dimensional cases the result is a "fractional Wiener surface", see the paper by Qian [4]. It uses the same covariance function as fractional Gaussian noise, except at post-processing the field is integrated (summed).

Postprocessor called after field generation.

This is called automatically by Field::generate().

Reimplemented from libfbm::SGPContext.
