Abstract:
A computer-readable medium containing instructions for controlling a computer system having a display to perform a method for generating and displaying at least two objects at different depths on said display with added realism, the method comprising:storing at least one predetermined 2-D image for each of said objects, each of said at least one predetermined 2-D image of said objects corresponding to the image of one of said objects to be rendered in a display sector of said raster display, each of said at least one predetermined 2-D image of said objects being defined based on a first and a second image rendering control value;computing a pair of x and y rendering reference coordinates and a relative depth value (z) for each of said objects, said x and y rendering reference coordinates and said z relative depth values of said objects describing geometric locations of said objects relative to a user's eye set at a predetermined location;computing a transformed set of coordinates by dividing said pair of x and y rendering reference coordinates by a function of (f(z)) of said z values to generate a parallax effect between said at least two objects;multiplying the transformed set of coordinates by a selected factor to enhance the parallax effect;selecting a predetermined 2-D image for each of said objects based on the object's transformed set of coordinates; andrendering said objects on said raster display using said selected 2-D images, said first and second image rendering control values of said selected 2-D images being determined using said transformed set of coordinates.
