First improve the Quadrilateral method fast convex hull algorithm to adapt it to the Pyramid convex hull algorithm, and then put forward the Initial approximate convex hull algorithm.Next to the working principle of the Initial approximate convex hull algorithm is expounded, and the concrete steps of implementing description.At last, through a large number of Experimental data to analyze the acceleration of the approximate convex hull efficiency and coarse convex hull the best choice of the number of edges.
