1. A method comprising:
- conducting a search of a database readable by an electronic device, said database comprising 2D or 3D representations of objects,using at least one graphical input parameter, wherein said graphical input parameter is a 2D or a 3D representation of all or part of an object;
receiving a set of results from said search;
inputting a new graphical input parameter;
searching said set of results with respect to said new parameter; and
obtaining a subset of said results.

Abstract
There are disclosed methods to provide stable pose determinations of various three dimensional shapes. Methods are also disclosed for determining multiple, unique drawing descriptors for two dimensional drawings, and for obtaining intermediate three dimensional representations of two dimensional drawings as one way to determine the descriptor. Methods are also disclosed to provide for searching of two dimensional drawings and three dimensional shapes using user-defined input, which may be a drawing or sketch. User interactivity is provided to further refine search results.

20. A method comprising:
-
providing a database of 2D and/or 3D objects, wherein said database is readable by an electronic device, wherein said database comprises 2.5D representations of said 2D and/or 3D objects; conducting a search of said database using at least one graphical input parameter, wherein said conducting comprises converting said graphical input parameter to a 2.5D representation of all or part of an object; and receiving a set of results from said search.
