초록

A wave form tile in the form of a natural wave, is provided to replace traditionally smooth surfaces to aid in more efficient shedding of a fluid medium. The wave form tile is also applied to proportionally spherical fractal surfaces defined for the surface of a vehicle.

1. A method for defining a spherically proportioned surface for a vehicle, comprising the following steps: (a) defining a vehicle surface enclosing a vehicle volume,(b) placing at least one first largest possible sphere within the vehicle volume,(c) placing at least one next largest possible sphere within the remaining space of the vehicle volume,(d) filling the remaining space of the vehicle volume with progressively smaller spheres until a predetermined minimum sphere diameter has been reached so that the vehicle volume is filled with spheres of progre...
