In mathematics, an Apollonian gasket or Apollonian net is a fractal generated from three circles, any two of which are tangent to one another
The method used to create the Apollonian gasket is based on circle inversion, which is a geometrical transformation acting with a reference circle that modifies points.
% In the plane, the inverse of a point P in respect to a circle of center O and radius R is a point P' such that P and P' are on the same ray going from O, and OP times OP' equals the radius squared
OP * OP' =R²

Thank you very much ! Useful and beautiful !
Nice piece of code.
Very good. Thx.
Here is link to this code in wikibooks/
is just that i wanted, thanks. Very usefull.
Good but useless, you already published "2D Apollonian gasket with n identical circles" which can deal 4 circles and which is more generic
