SurfaceCurvatureCreateFromGaussianAndMeanCurvatures Method

Create a SurfaceCurvature from a gaussian and mean curvature values using the relationship between the principal curvatures, gaussian and mean: kappa1 = mean + sqrt(mean*mean - gaussian) kappa2 = mean - sqrt(mean*mean - gaussian) If the radicand is negative, we assume we're dealing with a bit of numerical noise or estimates and set the principal curvatures: kappa1 = kappa2 = sign(mean)*sqrt(gaussian)

Syntax
Copy
public static SurfaceCurvature CreateFromGaussianAndMeanCurvatures(
	double gaussianCurvature,

Parameters

gaussianCurvature
Type: SystemDouble
Gaussian curvature = kappa1*kappa2 (product of principal curvatures).
meanCurvature
Type: SystemDouble
Mean curvature = (kappa1+kappa2)/2 (average of principal curvatures).

Return Value

Type: SurfaceCurvature
A SurfaceCurvature if successful, null otherwise.
