Hello.  
I’m using it well to find a distance-based path for the vtkDijkstraGraphGeodesicPath function. But I want to find a path that moves close based on the desired curvature value.

The [VTK: vtkDijkstraGraphGeodesicPath Class Reference](https://vtk.org/doc/nightly/html/classvtkDijkstraGraphGeodesicPath.html) link looks like I can use the UseScalarWeights() function, but it says experimental.

I tried several tests, but I couldn’t check if the function was applied.

Are there any other examples or materials or contents on how to use them?
