Abstract
A method for representing virtual information in a view of a real environment is provided that includes the following steps: providing a system setup comprising at least one display device, determining a position of a viewing point relative to at least one component of the real environment, providing a geometry model of the real environment, providing at least one item of virtual information and its position, determining a visualization mode of blending in the at least one item of virtual information on the display device according to the position of the viewing point and the geometry model, calculating a ray between the viewing point and the item of virtual information, and determining a number of boundary intersections by the ray, wherein if the number of boundary intersections is less than 2, the item of virtual information is blended in a non-occlusion mode, otherwise in an occlusion mode.
