Claim Text:
1. A sand art simulation system, which uses a computer to simulate a process of creating a sand art, comprising, an image analysis module receiving an image input to said computer, analyzing said image to obtain a plurality of contour lines of said image, types of said contour lines and a plurality of feature points of said contour lines, dividing said image into a plurality of blocks, analyzing gray levels of each said block and ways of spilling sand particles into said blocks; a sand mobility simulation module simulating behaviors of sand particles drifting from the air, sand movements and sand piling, and presenting a sand-spread plane on a screen; a sand manipulation module retrieving and computing said feature points of said contour lines according to said types of said contour lines, which are output by said image analysis module, and presenting said contour lines on said sand-spread plane sequentially; and a sand art rendering module simulating extents of light shielding according to heights of sand particles on said sand-spread plane, and simulating movements of sand particles after said contour lines are created on said sand-spread plane.
