Abstract
The 3D display device of the invention is based on an octree structure of data pertaining to an object to be displayed. This structure is memorized in a memory associated with a cache memory sending blocks of data on a bus to which a geometrical processor and an image-generating circuit are connected. The geometrical processor generates the visible part of another octree corresponding to a target universe which may be positioned in any way in relation to the object universe (a cube enclosing all the data to be represented).
