| Notes |
|
| (1) | This subclass covers: [6] |

| – | arrangements for geometrically modelling objects, whether the final model is used for display of an image of the object or for some other purpose, such as manufacture of a corresponding object; [6] |
|
| – | arrangements for analysing the geometric attributes of an image of an object. [6] |
|
| (2) | This subclass does not cover: [6] |
|
| – | reading or recognising printed or written characters or recognising patterns, e.g. fingerprints, which is covered by subclass G06K; [6] |
|
| – | modification of image data to allow display using multiple viewports, which is covered by subclass G09G; [6] |
|
| – | circuits for generating functions for visual indicators, which are covered by subclass G09G; [6] |
|
| – | scanning of documents or the like in pictorial communication, which is covered by subclass H04N. [6] |
