Patent ID: 8068111

Claim:
A method of increasing speed in virtual three dimensional (3D) application being applied to a game console, which comprises a processor and outputs N scan lines of a frame, the method comprising the steps of: providing N registers corresponding to the N scan lines; and interrupting the processor in a vertical blank period, wherein the step of interrupting comprises the sub-steps of: calculating N 3D operating parameters according to an operation provided to the game console by a user, wherein the i th 3D parameter corresponds to the i th scan lines; storing the 3D operating parameters into the registers, wherein the i th 3D operating parameter is stored in the i th register; and calculating a plurality of output scan lines, wherein k th outputted scan lines is calculated according to the k th scan lines and the k th 3D operating parameter, wherein “N”, “i” and “k” are nature number and 0<=i <=N, 0<=k <=N wherein the virtual 3D is a virtualization which uses the virtual 3D parameters to change the 2D display frame for obtaining a frame with 3D effect.
