Detailed Description

Object described by a function. The isosuface's surface is formed by all points where the given function is zero. Function value smaller than zero means inside the isosurface.

Constructor.

Parameters:

func	the function describing the surface
cont	container object
max	maximal second derivative
doeval	If eval is enabled the algorithm increases the max second derivative if it sees that this is necessary.
