Abstract: The present invention relates to a method of simplifying a geometry model, the method comprises: determination (607) of an integral error rating QiS defined as being a function of a sum of the error measures associated with the points of the plurality having a lower associated Morton code than the Morton code associated with the current point; determination (614) if a given set of points of the plurality can be simplified by a new point, the points of the given set all being the points of the plurality having a Morton code associated with one and the same prefix of given length, as a function at least of a difference between: —the integral error measure QlasS determined for the point of the given set having the largest Morton code (las); and—the integral error measure Qini-1S determined for the point of the plurality having an immediately lower Morton code (ini−1) than the smallest Morton code out of the Morton codes associated with the points of the set.
