public static class PolygonMath
The PolygonMath type exposes the following members.
Methods| Name | Description | |
|---|---|---|
  | GetClosedPolygonArea | Gets the area of a closed polygon. |
| GetClosedPolygonCentroid | Calculate the center of gravity (centroid) of the given closed polygon. The polygon has to be non-selfintersecting! |
| GetClosedPolygonCircumference | Gets the circumference of a closed polygon. |
| GetClosedPolygonSecondMoments(IEnumerableIntPoint) | Calculates the 2nd moments of the given closed polygon. The polygon has to be non-selfintersecting! |
| GetClosedPolygonSecondMoments(IEnumerableIEnumerableIntPoint) | Calculates the 2nd moments of the given closed polygons. The polygons have to be non-selfintersecting! |
| GetEigenValuesFromSecondMoments | Gets the eigenvalues from the second moments. |
| GetEigenVectorsFromSecondMoments | Gets the eigenvectors from the second moments. |
| GetOrientationAngleOfPrincipalAxisFromSecondMoments | Gets the orientation angle (in rad) of the principal axis from the second moments. |
 | ToIntPoints(IEnumerablePointD2D, Double, Double, Double, Double) | Creates integer polygon points from points consisting of doubles. The points can be transformed before converting to integers. First, the points are centered (x'=x-centerX, y'=y-centerY). Then the centered point is rotated. Lastly, the such transformated points is scaled. |
| ToIntPoints(IEnumerableValueTupleDouble, Double, Double, Double, Double, Double) | Creates integer polygon points from points consisting of doubles. The points can be transformed before converting to integers. First, the points are centered (x'=x-centerX, y'=y-centerY). Then the centered point is rotated. Lastly, the such transformated points is scaled. |
