Abstract: Described are methods of estimating a physical property associated with a region of a sports article. The method includes determining a plurality of structural features within the region, determining, for each structural feature, a feature value, mapping each feature value to a physical property, wherein the mapping is based on a machine learning algorithm from a limited plurality of samples, and wherein each sample associates a feature value with a value of the physical property, and using the mapping to estimate the physical property for the region.

Abstract: A technical solution is provided 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. One method aspect comprises the steps of piecewise partitioning the parametrization of the road segment into mutually independent curve segments, of 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, of generating a tessellation pattern for each curve segment based on the at least one tessellation factor, and of generating primitives, capable of being represented on a screen, on the basis of the generated tessellation pattern and on the basis of the parametrized road contour.
