<p>Objects (3, 4) of a three dimensional 3D virtual world that are represented on a two dimensional 2D image plane (6) are provided with labels (7, 8) which are generated in the 2D image plane (6) itself. The labels are in spatial registration with the object as represented on the 2D image plane. The generation of the labels in the 2D image plane avoids problems relating to perspective and aliasing which can occur when labels are provided in the virtual world itself and are rendered from the 3D virtual world.</p> |
