//! Provides a triangulation for a surface, a set of surfaces, or
//! more generally a shape.
//! A triangulation consists of an approximate representation
//! of the actual shape, using a collection of points and
//! triangles. The points are located on the surface. The
//! edges of the triangles connect adjacent points with a
//! straight line that approximates the true curve on the surface.
//! A triangulation comprises:
//! -   A table of 3D nodes (3D points on the surface).
//! -   A table of triangles. Each triangle (Poly_Triangle
//! object) comprises a triplet of indices in the table of 3D
//! nodes specific to the triangulation.
//! -   A table of 2D nodes (2D points), parallel to the table of
//! 3D nodes. This table is optional. If it exists, the
//! coordinates of a 2D point are the (u, v) parameters
//! of the corresponding 3D point on the surface
//! approximated by the triangulation.
//! -   A deflection (optional), which maximizes the distance
//! from a point on the surface to the corresponding point
//! on its approximate triangulation.
//! In many cases, algorithms do not need to work with the
//! exact representation of a surface. A triangular
//! representation induces simpler and more robust adjusting,
//! faster performances, and the results are as good.
//! This is a Transient class.
