Maximum Volume

Select this option to try each of the three methods described below, then use the method which produces the maximum volume.

Equiangular

Select this option to generate triangles which are equiangular in shape.

An Equiangular triangulation is a proximal method that satisfies the requirement that the radii of the circles drawn through the three vertices of each triangle are minimised and contain no other vertices.

Equilateral triangles are generated where all three sides are of equal length. Isosceles triangles are generated where two sides are of equal length.

Select the Equiangular triangulation option when you want to reduce the incidence of irregular-shaped (long and thin) triangles.

Minimum Surface Area

Select this option to apply a triangulation algorithm that computes a triangulation with a minimum surface area.

Proportional Length

Select this option to generate triangles between adjacent strings where the edges of the triangles are a similar proportional distance along the strings.

This method works best where the shape of adjacent strings are reasonably uniform. The starting edge for the triangulation is generated automatically using the closet pair of points on two adjacent strings. Triangles are then generated a proportional distance along each pair of strings.

Because no optimisation is applied to the triangulation, processing time is fast compared to an Equiangular or a Minimum Surface Area triangulation.

If string shapes are not uniform, the Equiangular and Minimum Surface Area algorithms are a better option.
