Abstract
In order to edit texture data for a 3D computer model, an image showing the 3D computer model with the texture data applied thereto is generated from a user-selected viewing direction and displayed to the user. Changes are made to the image data in accordance with user instructions. Corresponding changes are made to the texture data. To preserve texture data that the user did not wish to change and to retain the quality of the original texture data, processing is performed to amend the texture data which corresponds to only the image data that was changed and not texture data which corresponds to image data unchanged by the user. In addition, processing is performed to identify each polygon in the 3D computer model which is at an oblique angle to the viewing direction of the image displayed to the user. The identified polygons are then excluded from subsequent processing so that the texture data therefor is not changed.
