Automatic 3-D mesh generation technology has been applied very widely in finite element analysis,visualization in scientific computing and CIS.It has always been a research focus of scholars.Numerous mesh generation technologies can't avoid error of mesh.Because of heavy workload and not visualization,misjudge or undetected problem are always caused in mesh testing which is based on sampling spatial data.The tetrahedral mesh measuring with dispersing visualization method is presented.Using local transformation, 3-D Mesh have been displayed dispersedly, details of mesh is showed clearly .The mesh measuring is more intuitive and convenient,and the accuracy of the test is also enhanced.
