A method for operating a data goggles device , comprising the steps: - selecting at least two objects to be presented in a virtual reality from at least one perspective by means of data goggles of the data goggles device , which are each represented by a plurality of polygons in the virtual reality; - presetting a computing rule for rendering the objects for a computing unit of the data goggles device by an analyzing unit of the data goggles device , wherein the computing rule includes at least one presentation option saving computing time, which reduces the number of the polygons to be simultaneously presented by the data goggles device and/or the number of presentation effects for the polygons to be presented; - rendering at least one of the objects by the computing unit according to the preset computing rule; and - presenting the at least one rendered object in the virtual reality from the at least one perspective by means of the data goggles , characterized in that before presetting the computing rule, the positions of the objects in the virtual reality are captured by the analyzing unit , and by presetting the computing rule, setting the at least one perspective, by which a position and an associated viewing range are defined in the virtual reality, is effected such that only each one object is simultaneously presented by the data goggles device as the presentation option saving computing time, and the following steps are performed before presetting the computing rule: - estimating a computing power required in the computing unit of the data goggles device for a presentation of the objects in the virtual reality with a preset quality considering the number of the polygons, by the analyzing unit; and - examining if the required computing power is greater than a preset maximum computing power, by the analyzing unit ; wherein presetting the computing rule with the presentation option saving computing time is effected only in case of a positive result of the examination. - selecting at least two objects to be presented in a virtual reality from at least one perspective by means of data goggles of the data goggles device , which are each represented by a plurality of polygons in the virtual reality; - presetting a computing rule for rendering the objects for a computing unit of the data goggles device by an analyzing unit of the data goggles device , wherein the computing rule includes at least one presentation option saving computing time, which reduces the number of the polygons to be simultaneously presented by the data goggles device and/or the number of presentation effects for the polygons to be presented; - rendering at least one of the objects by the computing unit according to the preset computing rule; and - presenting the at least one rendered object in the virtual reality from the at least one perspective by means of the data goggles , characterized in that - estimating a computing power required in the computing unit of the data goggles device for a presentation of the objects in the virtual reality with a preset quality considering the number of the polygons, by the analyzing unit; and - examining if the required computing power is greater than a preset maximum computing power, by the analyzing unit ; <EOS>
