Class JXG.Sphere3D

JXG.GeometryElement3D,JXG.GeometryElement
↳ JXG.Sphere3D

Creates a new 3D sphere object. Do not use this constructor to create a 3D sphere. Use JXG.View3D#create with type Sphere3D instead.

Defined in: sphere3d.js.
Extends JXG.GeometryElement, JXG.GeometryElement3D.

Class Detail

JXG.Sphere3D(view, method, par1, par2, attributes)

A sphere consists of all points with a given distance from a given point. The given point is called the center, and the given distance is called the radius. A sphere can be constructed by providing a center and a point on the sphere or a center and a radius (given as a number or function).

Parameters:

{JXG.View3D} view

The 3D view the sphere is drawn on.

{String} method

Can be:

'twoPoints' – The sphere is defined by its center and a point on the sphere.
'pointRadius' – The sphere is defined by its center and its radius in user units.

The parameters p1, p2 and radius must be set according to this method parameter.

{JXG.Point3D} par1

The center of the sphere.

{JXG.Point3D} par2

Can be:

A point on the sphere (if the construction method is 'twoPoints')

A number or function (if the construction method is 'pointRadius')

{Object} attributes

An object containing visual properties like in JXG.Options#point3d and JXG.Options#elements, and optional a name and an id.

See:: JXG.Board#generateName

Field Detail

{Array} aux2D

Elements supporting the 2D representation.

{JXG.Point3D} center

The sphere's center. Do not set this parameter directly, as that will break JSXGraph's update system.

{GeometryElement} element2D

The 2D representation of the element.

{String} method

The construction method. Can be:

'twoPoints' – The sphere is defined by its center and a point on the sphere.
'pointRadius' – The sphere is defined by its center and its radius in user units.

See:: #center; #point2

{JXG.Point3D} point2

A point on the sphere; only set if the construction method is 'twoPoints'. Do not set this parameter directly, as that will break JSXGraph's update system.

See:: #method

{String} projectionType

The type of projection ('parallel' or 'central') that the sphere is currently drawn in.

Method Detail

{Number} Radius(value)

Calculates the radius of the circle.

Parameters:
{String|Number|function} value Optional: Set new radius

Returns:: {Number} The radius of the circle

{JXG.Sphere3D} setRadius(r)

Set a new radius, then update the board.

Parameters:
{String|Number|function} r: A string, function or number describing the new radius

Returns:: {JXG.Sphere3D} Reference to this sphere
