If the number of triangles exceeds MaximumTriangles 0 is returned.

This means that the client programmer needs to implement itself to get the index of the picked triangle. If the number of triangles doesn't exceed MaximumTriangles SoShape::createTriangleDetail() gets called. Against the default OpenInventor implementation which returns 0 as well Coin3d fills in the point and face indices.

void SoFCMeshNode::generatePrimitives ( SoAction * action ) [protected, virtual]

Sets the point indices, the geometric points and the normal for each triangle.

If the number of triangles exceeds MaximumTriangles then only a triangulation of a rough model is filled in instead. This is due to performance issues.
