Combination of 3D image data and graphics

Procedure for combining three-dimensional [3D] image data and auxiliary graphic data, comprising - obtaining the three-dimensional [3D] image data from an information carrier; - combining the three-dimensional [3D] image data and auxiliary graphic data in a visualization plane, characterized in that the method comprises - obtaining information of scaling and / or displacement of the information carrier; - depending on the scaling and / or displacement information obtained by scaling and / or shifting the three-dimensional [3D] image data to create a black bar spatial area that is not occupied by the scaled and / or three-dimensional [3D] image data displaced by respectively reducing the size of the three-dimensional [3D] image data and / or shifting the three-dimensional [3D] image data to create the black bar spatial area so that it is in an area of the viewing plane where no data is displayed image and to adjust the reduced or displaced three-dimensional [3D] image data in the remaining area of the display plane, in which the scaling and / or scrolling information comprises information indicating the presence of a scaling and / or offset allowed for enable scaling and / or scrolling of three-dimensional [3D] image data, and the procedure comprises depending on the same, the combination superimposing the three-dimensional [3D] image data and the auxiliary graphic data, or the combination of scaled and / or displaced three-dimensional [3D] image data and the auxiliary graphic data such that the auxiliary graphic data is placed within the area black bar space, in which the scaling and / or displacement information comprises at least one of: - a scale factor; - a scale factor that applies to scaling in both the x and y direction of the visualization plane - a lag in at least one of: - the horizontal direction of the visualization plane, and - the vertical direction of the visualization plane.
