20//KDE adapter is a "data source" adapter for
21//Marching cubes alhorithm. It produces scalar
22//values in regular grid's nodes, using TKDEFGT class
23//to estimate a density.
24//IMPORTANT: This class is not intended for end-user's code,
25//it's used and _must_ be used only as an argument while
26//instantiating mesh builder's class template.
27//That's why all members are protected
28//or private - end user cannot create object's of this class.
29//But mesh builder, derived from this class,
30//knows exactly how to use this class correctly.
31//SetDimenions and SetE/GetE are public members, it will be derived by mesh
32//builder's instantiation and used inside TGL5DPainter class.
