Syntax

virtual EMeshResult SplitEdge
(
    int EdgeAB,
    FEdgeSplitInfo & SplitInfo,
    double SplitParameterT
)

Remarks

Split an edge of the mesh by inserting a vertex. This creates a new triangle on either side of the edge (ie a 2-4 split). If the original edge had vertices [a,b], with triangles t0=[a,b,c] and t1=[b,a,d], then the split inserts new vertex f. After the split t0=[a,f,c] and t1=[f,a,d], and we have t2=[f,b,c] and t3=[f,d,b] (it's best to draw it out on paper...)

Returns

Ok on success, or enum value indicates why operation cannot be applied. Mesh remains unmodified on error.

Parameters

Parameter	Description
EdgeAB	index of the edge to be split
SplitInfo	returned information about new and modified mesh elements
SplitParameterT	defines the position along the edge that we split at, must be between 0 and 1, and is assumed to be based on the order of vertices returned by GetEdgeV()
