Abstract
A plurality of texture maps for a 3D computer model of an object are generated by processing images of the object, data defining the computer model, and data defining the relative positions and orientations of the images and computer model. A respective texture map is generated for the viewing position and direction of each image. Each texture map stores texture data for all parts of the computer model which are visible from the associated viewing position and direction and also texture data for all invisible parts of the computer model. Each texture map therefore stores texture data that can be used for rendering accurate images of the 3D computer model over a wide range of viewing positions and directions.
