Patent ID: 6888540

Claim:
A method of generating a plurality of images for display of a 3D scene from different viewpoints, comprising: generating a model of the scone using a homogenous coordinate system which uses first, second and third orthogonal axes and a homogeneity value (w); obtaining a first display image from a first viewpoint by transforming vertex positions from the 3D scene into vertex positions in a frustum viewing region using a projection matrix, the projection matrix having terms derived from the position of the viewpoint relative to the frustum viewing region; and obtaining one or more further display images from one or more further viewpoints aligned along the first axis with the first viewpoint and displaced from the first viewpoint by a multiple of a displacement value (dx), by updating the first axis value of the first display image by an amount substantially equal to k*dx/w, where k is a constant for each of the one or more further display images.
