    int ElementID,
    int SplitParentVertexID,
    const TArrayView< const int > & TrianglesToUpdate
)

Remarks

Create a new copy of ElementID, and update connected triangles in the TrianglesToUpdate array to reference the copy of ElementID where they used to reference ElementID. The new element will have the given parent vertex ID.

Returns

the ID of the newly created element

Parameters

Parameter	Description
ElementID	the element to copy
SplitParentVertexID	the new parent vertex for copied elements
TrianglesToUpdate	the triangles that should now reference the new element. Note: this is allowed to include triangles that do not have the element at all; sometimes you may want to do so to avoid creating a new array for each call.
