In a presentation device for two-dimensional, perspective projection of volume data elements of a volume dataset, the point of vision can be displaced along an optical axis and the point of vision and, with it, an acquired spatial angle can be rotated around at least one rotational axis with interactive inputs. The rotational axis intersects the optical axis in a pivot point that is determined dependent on the data values of volume data elements that lie within the acquired spatial angle, particularly on the optical axis or in the proximity thereof.
