Abstract
In this paper, we propose a new method for Objects indexing in three dimensions. We need to define our signature based on a 3D shape descriptor. We have to decompose the 3D-models into Spherical Squares Surfaces. The aims of the method are to minimize, the processing time on the 3D objects database and the searching time of similar objects to a request object. First, we start by defining our method that is based on the intersection of the 3D object with spheres and calculate the spherical surface area surrounding each point of the object. We then propose a distance that will be tested and prove its effectiveness in the search for similar objects in the database.
