The invention concerns a navigation method in 3D computer-generated pictures by 3D image manipulation. The invention concerns a technical device for selecting a file by manipulating a virtual 3D object (2). The 3D manipulation enables to rapidly access numerous data with complex and exponential tree networks, by intuitive interference, like turning a cube in one's hand. Said 3D navigation method is characterised in that it comprises a 3D volume (2), volume (2) whereof the centre is fixed and merges with the display surface of the device and symbolised by a marker: the pointer (3), volume (2) on the faces of which are displayed the representations of the selectable elements the objects (4), volume (2) manipulated in real time in the three degrees of freedom in rotation using a pointing device (trackball) for positioning the selected element on the pointer (3). The selection is triggered by clicking on a graphic button (5) of the pointing device (6).The objects (4) are represented by a graphic element derived from a digital file. With each object (4) is associated a link. The observer's viewpoint is fixed. The inventive device is particularly designed to facilitate quick access to a digital file in a large digital database. |
