Patent ID: 8212811

Claim:
A system for displaying on a screen a digital geometry data of an object in the form of a synthesis image, by means of an application module comprising a user interface, said application module delivering, from said digital geometry data, a model of said object formed by a stream of picture elements to a means for the calculation of a three-dimensional image which can be displayed on said screen, wherein said system comprises at least means for filtering said picture element stream, installed at the input of said means for the calculation of a three-dimensional image and comprising: means of discrimination, in said picture element stream, of elementary images each constituting at least one part of the image for display; means for coding each successive picture element according to an index value representing the content of said picture element; wherein said index value is a numerical value obtained by application of a hashing function to each successive elementary image; wherein said index values are delivered to said means for the calculation of a three-dimensional image, making it possible to increase the fluidity of the display by the display screen, by reconstituting the content of each elementary image by said means for the calculation of a three-dimensional image.
