Class Sphere

constructor

• new Sphere(center, radius): Sphere

• Parameters

  • center: number[]
  • radius: number

  Returns Sphere

center

diameter

northPole

radius

southPole

closestParameter

• closestParameter(testPoint): object

• Parameters

  • testPoint: number[]

    Point to project onto the sphere.

  Returns object

  [boolean, number, number] (boolean) true on success, false on failure. This function will fail if the point it coincident with the sphere center. (number) The longitudinal angle (in radians; 0.0 to 2pi) where the sphere approaches testPoint best. (number) The latitudinal angle (in radians; -0.5pi to +0.5pi) where the sphere approaches testPoint best.

  Description

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

closestPoint

• closestPoint(testPoint): number[]

• Parameters

  • testPoint: number[]

    Point to project onto Sphere.

  Returns number[]

  Point on sphere surface closest to testPoint.

  Description

  Returns point on sphere that is closest to given point.

encode

• encode(): object

• Returns object

  A js object.

  Description

  Encodes a sphere to json formatted data.

latitudeDegrees

    A number within the interval [0, 2pi].
  • latitudeRadians: number

    A number within the interval [-pi/2,pi/2].

  Returns number[]

  A point value.

  Description

  Evaluates the sphere at specific longitude and latitude angles.

toBrep

• toBrep(): Brep

• Returns Brep

  Description

  Converts this sphere is it Brep representation

toJSON

• toJSON(): object

• Returns object

  A js object.

  Description

  Encodes a sphere to json formatted data. Internally calls encode()

toNurbsSurface

• toNurbsSurface(): NurbsSurface

• Returns NurbsSurface

  A nurbs surface representation of this sphere or null.

  Description

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