Element Detail
Sphere3D
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).
If the radius is a negative value, its absolute value is taken.
-
This element has no direct constructor. To create an instance of this element you have to call JXG.Board#create
with type "sphere3d".
- Possible parent array combinations are:
-
{JXG.Point3D} center
{number|JXG.Point3D} radius
- The center must be given as a JXG.Point3D (see JXG.providePoints3D),
but the radius can be given as a number (which will create a sphere with a fixed radius) or another JXG.Point3D.
If the radius is supplied as number or the output of a function, its absolute value is taken.
- Throws:
- {Exception}
- If the element cannot be constructed with the given parent objects an exception is thrown.
- Examples:
var view = board.create(
'view3d',
[[-6, -3], [8, 8],
[[0, 3], [0, 3], [0, 3]]],
{
xPlaneRear: {fillOpacity: 0.2, gradient: null},
yPlaneRear: {fillOpacity: 0.2, gradient: null},
zPlaneRear: {fillOpacity: 0.2, gradient: null}
}
);
// Two points
var center = view.create(
'point3d',
[1.5, 1.5, 1.5],
{
withLabel: false,
size: 5,
}
);
var point = view.create(
'point3d',
[2, 1.5, 1.5],
{
withLabel: false,
size: 5
}
);
// Sphere
var sphere = view.create(
'sphere3d',
[center, point],
{}
);
