<p>In a method of providing a GUI for entering a command (27) for a processing device, an image is generated and a pointer is provided to select a location (9) in the image, referring to the command (27). The image is generated by rendering at least part of a three-dimensional scene from a dataset (18), which comprises entries specifying paths (5) traced in a plurality of directions from a viewpoint (4) in the scene to first points in the scene. Each location (9) in the image is associated with one of the paths (5) comprised in the dataset (18). Selecting the location (9) results in selecting the associated path (5). A path (5) is linked to the command (27). A programmable processing device comprises a GUI provided using such a method.</p> |
