CentroidCoordinatesPrincipalMoments(out double x, out Vector3d xaxis, out double y, out Vector3d yaxis, out double z, out Vector3d zaxis)

Calculates the eigenvalues and eigenvectors of the moments matrix with respect to centroid coordinates.

CentroidCoordinatesPrincipalMomentsOfInertia(out double x, out Vector3d xaxis, out double y, out Vector3d yaxis, out double z, out Vector3d zaxis)

Calculates the principal moments of inertia and principal axes with respect to centroid coordinates.

Compute(Curve curve, bool length, bool firstMoments, bool secondMoments, bool productMoments)

Calculates the length mass properties of a curve.

Compute(Curve curve)

Calculates the length mass properties of a curve.

Compute(IEnumerable<Curve> curves, bool length, bool firstMoments, bool secondMoments, bool productMoments)

Calculates the length mass properties of an enumeration of curves.

Compute(IEnumerable<Curve> curves)

Dispose()

Actively reclaims unmanaged resources that this instance uses.

Dispose(bool disposing)

For derived class implementers.
This method is called with argument True when class user calls Dispose(), while with argument False when the Garbage Collector invokes the finalizer, or Finalize() method.
You must reclaim all used unmanaged resources in both cases, and can use this chance to call Dispose on disposable fields if the argument is true.
Also, you must call the base virtual method within your overriding method.

WorldCoordinatesPrincipalMoments(out double x, out Vector3d xaxis, out double y, out Vector3d yaxis, out double z, out Vector3d zaxis)

Calculates the eigenvalues and eigenvectors of moments matrix in world coordinates.

WorldCoordinatesPrincipalMomentsOfInertia(out double x, out Vector3d xaxis, out double y, out Vector3d yaxis, out double z, out Vector3d zaxis)

Calculates the principal moments of inertia and principal axes with respect to world coordinates.
