Methods by Which a Curve Is Calculated
Unlike point curves, there are a number of Methods, which can be chosen from the Method option menu, for calculating the final curve that results.
|Method||Data points or vertices of element define|
|Control Points||Vertices of the control polygon.|
|Through Points||Points on the curve.|
|Least Squares by Tolerance and Least Squares by Number||A set of points that the curve approximates or is "fit" to.|
|Catmull-Rom||A set of points that is closely approximated.|
These illustrations show the different types of B-spline curves constructed from the same line string.
