Other parameters

The remaining parameters “Segments”, “Tolerance” and “Iterations” are internal control parameters that influence precision and speed of the filter. “Segments” is a number of control points along the hub and shroud patches. Raising the number of control points can increase the resolution of the approximated patches. “Tolerance” is proportional to the allowed absolute error in determination of point’s transformed coordinates img3 1. The number should generally be smaller than the typical distance between two points in the original mesh. “Iterations” is the iteration limit set for determination of the transformed coordinates. It should not be necessary to raise the default value, unless an extremely fine mesh is being transformed.
