Parameters

Root

Array of doubles defining the root point

Normal

Array of doubles defining the direction vector

Return Value

• in-process, unmanaged C++: Pointer to an array to hold the edge pointers 

See In-process Methods for details about this type of method.

These edges are not added to the face and cannot be found using IFace2::IGetEdges. They are created and handed back to the caller as an array of edges packed with edges.

The vector root point (root) and a vector direction (normal) define the orientation for the silhouette edge creation.

The return array has two elements for each edge: the first is the silhouette edge and the second is  not used. To iterate through the edges, an application needs to step through every second element.

Before calling this method, call IFace2::IGetSilhoutteEdgeCount to get the size of array required to hold the edges.

The returned edges are transient and cannot be selected.
