Method for acceleration of virtual three-dimensional image

The invention relates to a virtual three-dimensional image acceleration method. The method is applicable to amusement equipment, which comprises a processor. The amusement equipment is used to output a plurality of scanning lines of a picture. The method comprises the following steps: providing a plurality of cache memories to correspond to the scanning lines; and during a vertical blank period, performing an interruption program on the processor, wherein the interruption program comprises: calculating a plurality of three-dimensional computation parameters corresponding to the scanning lines based on an operation by a user on the amusement equipment; recording the three-dimensional computation parameters in the cache memories; and calculating the output scanning lines based on the scanning lines and the three-dimensional computation parameters corresponding to the scanning lines. The method decreases the required interruption times of the processor by providing corresponding cache memory to each scanning lin
