Abstract

A method of preparing on a first device object files used for rendering two-dimensional images of threes-dimensional objects on a second device by processing object files containing data defining triangle primitives representing at least one three-dimensional object to determine a rendering order in which the triangle primitives may be rendered for creating a two-dimensional image in which the hidden surfaces are removed. A plurality of planar triangle primitives corresponding to a plurality of surface portions of the at least one object as vertex data are stored on the first device. The method can be used in a mobile phone.
