Sphere

Sphere struct

Represents the plane and radius values of a sphere.

Derived Classes:

Namespace: Rhino.Geometry
Sphere: references

Constructors (2)

Sphere(Plane equatorialPlane, double radius)

Initializes a new sphere given the plane of the equator circle and radius.

Sphere(Point3d center, double radius)

Initializes a new sphere given center point and radius.

Properties (10)

BoundingBox

Gets the world aligned bounding box for this Sphere. If the Sphere is Invalid, an empty box is returned.

Center

Gets or sets the center point of the sphere.

Diameter

Gets or sets the diameter for this sphere.

EquatorialPlane

Gets or sets the Equatorial plane for this sphere.

EquitorialPlane

Gets or sets the Equatorial plane for this sphere.

IsValid

Gets a value that indicates whether the sphere is valid.

NorthPole

Gets the point at the North Pole of the sphere.
This is the parameterization singularity that can be obtained, at V value +Math.Pi/2.

Radius

Gets or sets the Radius for this sphere.

SouthPole

Gets the point at the South Pole of the sphere.
This is the parameterization singularity that can be obtained, at V value -Math.Pi/2.

Unset

Gets a sphere with invalid members.

Methods (19)

ClosestParameter(Point3d testPoint, out double longitudeRadians, out double latitudeRadians)

Finds the angle parameters on this sphere that are closest to a test point.

ClosestPoint(Point3d testPoint)

Returns point on sphere that is closest to given point.

EpsilonEquals(Sphere other, double epsilon)

Check that all values in other are within epsilon of the values in this

FitSphereToPoints(IEnumerable<Point3d> points)

Attempts to fit a sphere to a collection of points.

LatitudeDegrees(double degrees)

Computes the parallel at a specific latitude angle.
The angle is specified in degrees.

LatitudeRadians(double radians)

Computes the parallel at a specific latitude angle.
The angle is specified in radians.

LongitudeDegrees(double degrees)

Computes the meridian at a specific longitude angle.
The angle is specified in degrees.

LongitudeRadians(double radians)

Computes the meridian at a specific longitude angle.
The angle is specified in radians.

NormalAt(double longitudeRadians, double latitudeRadians)

Computes the normal at a specific angular location on the sphere.

PointAt(double longitudeRadians, double latitudeRadians)

Evaluates the sphere at specific longitude and latitude angles.

Rotate(double angleRadians, Vector3d axisOfRotation, Point3d centerOfRotation)

Rotates this sphere about a point and an axis.

Rotate(double angleRadians, Vector3d axisOfRotation)

Rotates the sphere about the center point.

Rotate(double sinAngle, double cosAngle, Vector3d axisOfRotation, Point3d centerOfRotation)

Rotates this sphere about a point and an axis.

Rotate(double sinAngle, double cosAngle, Vector3d axisOfRotation)

Rotates this sphere about the center point.

ToBrep()

Converts this sphere is it Brep representation

ToNurbsSurface()

Converts this sphere to its NurbsSurface representation. This is synonymous with calling NurbsSurface.CreateFromSphere().

ToRevSurface()

Converts this Sphere to a RevSurface representation. This is synonymous with calling RevSurface.CreateFromSphere().

Transform(Transform xform)

Transforms this sphere. Note that non-similarity preserving transformations cannot be applied to a sphere as that would result in an ellipsoid.

Translate(Vector3d delta)

Moves this sphere along a motion vector.
