ABSTRACT:
A three-dimensional object data processing method and system reduces the number of coordinate calculations of the objects when an eyepoint changes during CG processing. A workstation (2) comprises a space searching module (6) which searches for the objects included in a view volume, a rasterizing module (12) which displays the view volume, and a texture data generating module (10) which groups a plurality of objects according to a user's request and generates two-dimensional texture data. Each object is drawn as texture data.
