Detailed Description

Blanc and Shlick finite field function.

This function is due to the Blanc and Shlick publication from Implicit Surfaces '95. The function allows a range of blending hardness with less computational effort than the arctan field.

jbt_blanc_field::jbt_blanc_field( jFlt _h = 0 )

Creates a new Blanc field. The hardness parameter should be >= 0, the result is undefined with h<0. The higher the value the harder the blend.

jFlt jbt_blanc_field::f( jFlt r, jFlt R ) const

Reimplemented from jbt_field.
