【Abstract】 There are two major algorithms in Surface/Surface Intersection: Geometric Segments and Numerical Tracing; for the sake of system’s stability and accuracy, a reasonable and Topo_coherented algorithm is needed when one computes the surface and surface intersection.A new method is presented to compute the intersection using projection,by which the above problem can be solved successfully.更多还原
