Abstract: The invention discloses a method for processing image objects in three-dimensional displays, wherein an image object is displayed by an image generating means in a virtual image space, wherein pixels of the three-dimensional image space can be reached by a selection device, and wherein a computer allocates coordinate values to the image object in accordance with its position. At least one pixel of the image object is marked for processing by the selection device. The invention also discloses an apparatus for processing and modifying three-dimensional displays, the apparatus comprising a computer for generating image data, a display screen for displaying the image data in three-dimensional form in a virtual image space, and a pointing device for manually influencing the three-dimensional display.
