GetTriangleNodeInd exArray (PolygonMesh) *

Introduced

5.0

Description

Returns the node indices of the polygon subtriangle on which the point locators are defined.

Each node index triplet is guaranteed to correspond to one polygon (the one returned by PolygonMesh.GetPolygonIndexArray). The barycentric position within the triangle can be queried with PolygonMesh.GetTriangleWeightArray.

Warning: This information may in some cases 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 method's description.
