SortByMinimumSpanningTreePosition
Parameters
inputPointsInput list of points. The points form a continuous line from the first to last point.
outputParametersParameters used by vtkParametricPolynomialApproximation to approximate a polynomial from the input points.

◆ SortByMinimumSpanningTreePosition()

static void vtkCurveGenerator::SortByMinimumSpanningTreePosition ( vtkPoints *  inputPoints,
vtkDoubleArray *  outputParameters 
)
static

Calculates point parameters for use in vtkParametricPolynomialApproximation The parameter values are calculated using the following algorithm:

  1. Construct an undirected graph as a 2D array
  2. Find the two vertices that are the farthest apart
  3. Run prim's algorithm on the graph
  4. Extract the "trunk" path from the last vertex to the first
  5. Based on the distance along that path, assign each vertex a polynomial parameter value

    SortByIndex
    Parameters
    inputPointsInput point cloud that should be sorted to form a continuous line.
    outputParametersParameters used by vtkParametricPolynomialApproximation to approximate a polynomial from the input points.
