Claim One:
1. A method for graphical representation of road segments by employing hardware tessellation, wherein cartographic data that describe at least one two-dimensional or three-dimensional road contour of the road segment are assigned to each road segment, the method comprising the following steps: providing of a parametrisation that describes the road contour of a road segment; piecewise partitioning the parametrisation of the road segment into mutually independent curve segments; providing at least one tessellation factor for each curve segment, the at least one tessellation factor specifying into how many subsegments each curve segment is to be subdivided in the direction of the road contour; generating a tessellation pattern for each curve segment based on the at least one tessellation factor; and generating primitives, capable of being represented on a screen, on the basis of the generated tessellation pattern and on the basis of the parametrised road contour.
