Patent ID: 8217990

Claim:
A stereoscopic picture generating apparatus comprising: a storage device for storing information indicative of positions of a plurality of predetermined eye positions; and a processing unit for creating a stereoscopic picture of a three-dimensional model based on the information, wherein said processing unit creates two-dimensional images that are rendered as images of the three-dimensional model from converted eye positions, wherein the two dimensional images are created by applying conversion, the conversion is applied by calculating a two-dimensional image position at an eye point e for global position coordinate values vs_k of apex data of a model M i, a calculation is performed using the projection matrix P ei preserved in the model M i, [ ax ay az ] ← P ei · ( vs j - p ei ) u k ← [ ax az + 1 ay az + 1 ] wherein, f xi = f xj ⁢ 1 p ejz + 1 , f yi = f yj ⁢ 1 p ejz + 1 q xi = f xi ⁢ p ejx , q xy = f yi ⁢ p ejy P ei = [ f xi 0 q xi 0 f yi q yi 0 0 1 ] , f_x, f_y represent vertical and horizontal values in three-dimensional plane; p_ex, p_ey, p_ez represent eye point position represented in three dimensional vector; ax, ay, az are positions in three-dimensional coordinate wherein of different parameters are used for different ones of the predetermined eye positions during the conversion, wherein each of the parameters is set to make a distance between the converted eye positions shorter than a distance between the predetermined eye positions, and to make a distance between a screen on which the two-dimensional images are rendered and the converted eye positions shorter than a distance between the screen and the predetermined eye positions, wherein said processing unit displays each of the two-dimensional images which are switched from one converted eye position to another.
