Class JXG.Circle3D
JXG.GeometryElement3D,JXG.GeometryElement
↳ JXG.Circle3D
Creates a new 3D circle object. Do not use this constructor to create a 3D circle. Use JXG.View3D#create with
type Circle3D instead.

Class Detail
JXG.Circle3D(view, center, normal, radius, attributes)
In 3D space, a circle consists of all points on a given plane with a given distance from a given point. The given point is called the center, and the given distance is called the radius.
A circle can be constructed by providing a center, a normal vector, and a radius (given as a number or function).
- Parameters:
- {JXG.View3D} view
- The 3D view the circle is drawn on.
- {JXG.Point} center
- The center of the circle.
- {Array} normal
- A normal vector of the plane the circle lies in. Must be either an array of three numbers or an array of three functions returning numbers.
- {Number|Function} radius
- The radius of the circle.
- {Object} attributes
Field Detail
{JXG.Point3D}
center
The circle's center. Do not set this parameter directly, as that will break JSXGraph's update system.
<private>
{Array}
normal
A normal vector of the plane the circle lies in. Do not set this parameter directly, as that will break JSXGraph's update system.
- See:
- updateNormal
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.Circle3D}
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.Circle3D} Reference to this sphere
