EvenAsphericSurface

public class AsphericSurface
extends QuadricSurface

Prtoected class to impements a general AsphericSurface. The distance calcualtion requires itteration, so use of this type of surface will be significantly slower than analyic surfaces.

Field Summary

double	accuracy The convergence accuracy, by defaults set to 100 or the default wavelength.
protected Aspheric	surface The Aspheric surface profile
