v5.0
Returns the barycentric weight triplets describing the position within the polygon subtriangle
on which the point locators are defined.
The components defining the subtriangle queried with methods PolygonMesh.GetTriangleVertexIndexArray
and PolygonMesh.GetTriangleNodeIndexArray.
Notice that this information may exceptionally vary between geometry
instances having the same topology but different deformations.
Since the point locators are defining a precise position on the surface,
and since deformations can dynamically change the triangulation within a
polygon, it can happen that a point locator is remapped to a different subtriangle
(both barycentric weights and subtriangle indices can vary).
An example using this method can be found in PolygonMesh.GetPolygonIndexArray
and Geometry.GetClosestLocations methods' description.
