A system includes a 3-D display device with a display screen, an addresser for addressing the 3-D screen, and a renderer having an input for a 3-D model and an input for at least one viewpoint for rendering image information for supply to the addresser. The renderer includes an initial part having an input for the 3-D model and for a main view point for rendering objects in the form of a main view point Z-stack. The Z-stack includes stack layers having RGB and Z-values. The renderer further includes a Z-stack constructor in which, from the main view point Z-stack generated by the initial stage, Z-stacks for additional viewpoints are constructed. An image information occlusion semantics stage is provided for generating image information from the Z-stacks.
