英文摘要	High accuracy surface modeling (HASM) developed in terms of the fundamental theorem of surfaces has theoretically given a solution to the error problem. However, HASM had a huge computation cost and very large memory cost because it must solve a partial differential equation set for simulating each lattice of surface, which make HASM difficult to be widely applied. As multi-grid method is well known as a fastest solution for the elliptic partial differential equations, we apply multi-grid method in the process of HASM. Numerical tests show that multi-grid method is efficient for HASM whilst it keeping the accuracy of the solutions, and it solves the memory problem of HASM as well.
