Parameters

sum: Type: System Double
Integral of the function 1 over the area of the polygon.

sumX: Type: System Double
Integral of the function x over the area of the polygon.

sumY: Type: System Double
Integral of the function y over the area of the polygon.

sumXX: Type: System Double
Integral of the function x2 over the area of the polygon.

sumYY: Type: System Double
Integral of the function y2 over the area of the polygon.

sumXY: Type: System Double
Integral of the function xy over the area of the polygon.

Remarks

Compute the zeroth, first, and second moments of area of this polygon. All results are zero if NumVertices is less than 3.
