Abstract
A method for increasing speed in virtual 3D application is applied to a game console, which includes a processor and is used for outputting scan lines of a frame. The method includes the steps of: providing registers corresponding to the scan lines; and interrupting the processor in a vertical blank period. The step of interrupting includes: calculating 3D operating parameters corresponding to the scan lines according to an operation provided to the game console by a user; storing the 3D operating parameters into the registers; and calculating outputted scan lines according to the scan lines and the corresponding 3D operating parameters. Since the registers respectively corresponding to the scan lines are provided, the number of times of interrupting the processor can be decreased and the efficiency can be greatly increased.
