Description

Compute the total UVLength/MeshLength ratio along the given VertexPath. Other 3D lengths can then be scaled to comparable UV-space lengths by multiplying by this value. Edges must exist between the vertices along the path, and loops are not considered. Each UV edge for a 3D edge is considered, ie if a 3D edge corresponds to 2 UV edges, both are counted, and if the 3D edge has no UV edges, it is skipped.

namespace UE  
{  
    namespace Geometry  
    {  
        double UE::Geometry::ComputeAverageUVScaleRatioAlongVertexPath  
        (  
            const FDynamicMesh3 & Mesh,  
            const FDynamicMeshUVOverlay & UVOverlay,  
            const TArray < int32 > & VertexPath,  
            double * PathLengthOut,  
            double * UVPathLengthOut  
        )  
    }  
}

UVPathLength / PathLength, or 1.0 if no valid UV edges along the path existed
