Constructor & Destructor Documentation

IG::Num::Func3d2dExamples::SnailConicSpiral_ToCheck::SnailConicSpiral_ToCheck ( ) [inline]

Constructs parametric definition of a snail shell-like parametric surface with some default parameters.

IG::Num::Func3d2dExamples::SnailConicSpiral_ToCheck::SnailConicSpiral_ToCheck	(	double	a,
		double	b,
		double	c,
		double	n
	)		`[inline]`

Creates a parametric definition of a snail shell/like surface with the specified parameters.

Parameters:

a	Ratio between spiral diameter and height of one turn.
b
c	Defines radius of free space spiral turns. 0 means there is no hole in the middle.
n	Number of full turns of the spiral.
