SurfaceCurvature Properties |
The SurfaceCurvature type exposes the following members.
Properties| Name | Description | |
|---|---|---|
 | Gaussian |
The Gaussian curvature is kappa1*kappa2.
|
| IsNaN |
True if either of kappa1 or kappa2 is NaN.
|
| IsSet |
True if kappa1 and kappa2 are both valid finite values.
|
| IsUnset |
True if either of kappa1 or kappa2 is not a valid finite value.
|
| IsZero |
True if both kappa1 and kappa2 are zero.
|
| MaximumPrincipalCurvature |
If set, the maximum of kapp1 and kappa2 returned.
Otherwise, the quiet NaN is returned.
|
| MaximumRadius |
If a principal curvature value is zero or the principal curvatures have opposite signs,
then the maximum radius of curvature is infinite RhinoMath.InfiniteRadius is returned.
Otherwise the maximum radius of curvature is 1/min(fabs(kappa1),fabs(kappa2)).
|
| Mean |
The mean curvature is (kappa1+kappa2)/2.
|
| MinimumPrincipalCurvature |
If set, the minimum of kappa1 and kappa2 returned.
Otherwise, the quiet NaN is returned.
|
| MinimumRadius |
The minimum radius of curvature is 1/max(fabs(kappa1),fabs(kappa2)).
Infinite radius values are returned as RhinoMath.InfiniteRadius.
|
| Normal |
Gets the normal direction of the surface at the u,v parameter where the surface curvature was evaluated.
|
| Point |
Gets the point at the u,v parameter where the surface curvature was evaluated.
|
| UVPoint |
Gets the u,v parameter where the surface curvature was evaluated.
