Method for generating stereographic image using Z-buffer

A method for generating stereographic images using the Z-buffer, comprising the steps of:

• a) creating the first two-dimensional image for one eye of a viewer by rendering a three-dimensional model, and storing color information and depth information of said first two-dimensional image in the frame buffer and said Z-buffer, respectively;
• b) creating the second two-dimensional image for the other eye of the viewer on the basis of said first two-dimensional image, said color information stored in said frame buffer, and said depth information stored in said Z-buffer;
• and
• c) generating said stereographic image on the basis of said first two-dimensional image and said second two-dimensional image;
• wherein said step b) includes the steps of:
• b-1) searching said first two-dimensional image for pixels corresponding respectively to pixels of said second two-dimensional image;
• and
• b-2) interpolating color values of the searched pixels of said first two-dimensional image and obtaining color values of said second two-dimensional image according to the interpolated results.
