Definitions

  • DE 1 03 56 020 discloses a method and a device for displaying and / or transmitting three-dimensional objects, in particular virtual shops and mails, especially mobile terminals of a communication network.
  • the inventive method is used to display a three-dimensional object, wherein the three-dimensional object is displayed depending on control commands from different angles. It is essential that the object is displayed with at least one display area that is displayed on the display. ge Formation a moving image is displayed and that the display area with the moving image displayed on the display surface is displayed depending on the control commands from different angles.
  • the present invention extends the previously known representations of three-dimensional objects by integrating a moving image on a display surface. Due to the fact that, depending on the control commands, not only the three-dimensional object but also the display surface with the moving image displayed on the display surface is represented from different angles, the viewer perceives the display surface with moving image as part of the object.
  • This extension provides additional information about the moving image to the user.
  • the attractiveness of the object can be increased by displaying advertising information on the display area as a moving picture.
  • the user receives a more realistic representation, since in the virtual representation of the three-dimensional object as well, a moving image is preferably located at the location of the display area of the object real three-dimensional object is displayed.
  • the display area is displayed in a fixed spatial arrangement with respect to the three-dimensional object.
  • the user assigns the display area to the display surface because of the constant spatial arrangement relative to the object.
  • the display area is displayed as part of the surface of the three-dimensional object.
  • the user immediately recognizes the display area as part of the displayed three-dimensional object.
  • a polygon mesh is generated for the representation of the three-dimensional object, for an approximate description of the contours of the three-dimensional object.
  • the approximate description of the contours of the three-dimensional object by means of a polygon mesh has the advantage that a representation with a reduced data volume is possible.
  • the density of the mesh can be selected.
  • a coarser polygon mesh for example in the case of overall view, and a finer mesh mesh in detailed view can be displayed, so that overall the necessary data volume to be transmitted can be reduced.
  • the invention is not limited to such display areas.
  • any desired shaped and / or structured display surfaces can be represented, in particular by making use of the previously described approximation of the shape of the display surface by a polygon mesh.
  • the number n of polygons for describing the display area thus also depends on the shape and structure (eg, a deflection of the display area, a ripple or other U Maunism). It is located in According to the invention, the display area is described by a multiplicity of polygons, in particular by a number n> 1 0 and n> 1 00.
  • the aforementioned polygons P completely cover the display area, so that the moving image can be displayed on the complete display area.
  • the polygons P 1 it is advantageous for the polygons P 1 to be selected such that a circumferential edge of marginal polygons corresponds to a peripheral edge of the display area.
  • the subdivision between a surface of the object outside the display area and within the display area thus runs along boundary lines between polygons in this advantageous embodiment.
  • a texture is assigned to the remaining polygons not assigned to the display surface.
  • Such a texture can be taken from a database of textures to give a realistic representation of the actual surface texture of the three-dimensional object.
  • the textures of the remaining polygons are taken from photographic images of the three-dimensional object.
  • a film is preferably used as a moving picture.
  • an additional acoustic output takes place.
  • further information can be transmitted to the user not only through the moving image but also through the acoustic output, or the perception of the illustrated three-dimensional object can be further enriched via corresponding noises and / or music.
  • At least two acoustic output points are preferably predefined on the three-dimensional object.
  • An output point thus preferably represents a loudspeaker of the real object on which the acoustic output takes place.
  • the acoustic output preferably takes place as a function of the illustrated viewing angle. If the viewing angle is changed together with the virtual representation and if the position of the acoustic output point thereby also changes, this change in location is preferably also made during the acoustic output by the real loudspeakers of a display unit on which the object is displayed to the user. considered.
  • the method according to the invention in particular a preferred embodiment thereof, is preferably used with display units such as monitors, in particular computer monitors, televisions, tablet monitors or comparable screens, in order to reproduce the object on this screen.
  • display units such as monitors, in particular computer monitors, televisions, tablet monitors or comparable screens, in order to reproduce the object on this screen.
  • Typical display units such as the abovementioned screens, in particular monitors or televisions or computer units with a monitor or television, typically have at least two loudspeakers for a display. reo audio output on.
  • a spatial change of the acoustic output point when changing the viewing angle in a preferred embodiment can be taken into account via these two channels. For example, if the output point is located on the right-hand side, the acoustic output can be amplified by a right-hand loudspeaker and vice versa, provided that the issue point is more on a left side.
  • the distance of the acoustic output points to the viewer's location for the currently displayed viewing angle is preferably taken into account in the acoustic output, in particular by reproducing an acoustic signal of a farther distant output point at a reduced volume compared to the acoustic signal of a less far from the Location of viewer remote output point.
  • the acoustic output of each output point will be at a higher volume at the loudspeaker closest to the output point than at speakers farther from the output point.

  • two acoustic output points are predetermined on the three-dimensional object.
  • the real three-dimensional object being displayed also has two loudspeakers, in particular when the object shown is a monitor or television with two loudspeakers.
  • a stereo output can be used to underlay the moving picture. If, for example, the observer changes the viewing angle, so that in the current representation the left loudspeaker of the displayed object comes to rest on the right side and the right loudspeaker on the left side, the actual output can be made with reverse channels, so that the illustrated spatial arrangement of the speakers is taken into account.
  • the reproduction of the moving image is started by the user.
  • the playback of the moving image can be started and / or stopped by selecting the display area by the user by means of a virtual pointer element. This can be done, for example, by clicking on the user interface with a mouse pointer or by tapping on a touch-sensitive display.
  • the three-dimensional object is preferably displayed on a two-dimensional display unit, in particular a screen as described above, a computer monitor or corresponding display of a tablet, smartphone or television.
  • the method according to the invention is suitable for displaying any three-dimensional objects. It is particularly advantageous that the three-dimensional object comprises a display unit. This gives the user a more realistic impression since the actual display unit can also be better experienced in the virtual display, even if a moving image is displayed in the virtual display. In particular, it is therefore advantageous that the three-dimensional object is a screen or a technical device with a screen, such as a television, tablet and / or smartphone.
  • viewing angle-dependent properties of the real display unit of the three-dimensional object are taken into account in the display of the display unit with the current viewing angle. It is known that in opti's ads, especially monitors or TVs, the optical impression changes depending on the angle. Typically, the best picture results when the user looks at the display approximately along a normal vector which is perpendicular to the display area. When viewing the display obliquely (depending on the quality of the display), the image quality often deteriorates with increasing angle to the surface normal of the display.
  • this change is taken into account by calculating the viewing angle on the display unit when specifying a viewing angle for the representation of the three-dimensional object, in particular preferred angles to a surface normal of the display unit, and the moving image is selected and / or modified to reproduce the changed visual perception due to the current angle of view on the display unit.
