Abstract: A computerized method employing isosceles triangles for generating boundary surface points includes providing an electronic computer system having instructions and data for performing steps, and then performing those steps by executing the instructions and data in the computer system. Each isosceles triangle employed in the method has two congruent legs and an incongruent base. The steps include detecting a closed edge, determining a base figure having a perimeter, generating after the determining step a first group of isosceles triangles having vertices coincident with the closed edge and having bases formed by and equal to the perimeter, determining a location vector formed by a unitized cross product of first line segments which connect the vertices of the first group of triangles.
