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.
p1,p2andradiusmust 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')
- A point on the sphere (if the construction method is
- {Object} attributes
- An object containing visual properties like in JXG.Options#point3d and JXG.Options#elements, and optional a name and an id.
Field Detail
<private>
{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.
{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:
- JXG.Sphere3D#method
{String}
projectionType
The type of projection (
'parallel' or 'central') that the sphere is currently drawn in.
