G06T
IMAGE DATA PROCESSING OR GENERATION, IN GENERAL ( specially adapted for particular applications, see the relevant subclasses, e.g. G06K, G09G, H04N )
NOTE
-
This subclass covers:
- 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;
- arrangements for analysing the geometric attributes of an image of an object.

This subclass does not cover:
- reading or recognising printed or written characters or recognising patterns, e.g. fingerprints, which is covered by subclass G06K;
- modification of image data to allow display using multiple viewports, which is covered by subclass G09G;
- circuits for generating functions for visual indicators, which are covered by subclass G09G;
- scanning of documents or the like in pictorial communication, which is covered by subclass H04N.

WARNING
-
The following IPC groups are not used in the CPC scheme. Subject matter covered by these groups is classified in the following CPC groups:
