Element Detail
Circle3D
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).
If the radius has a negative value, its absolute value is taken. If the radius evaluates to NaN, the circle is not displayed. This is convenient for constructing an intersection circle, which is empty when its parents do not intersect.
-
This element has no direct constructor. To create an instance of this element you have to call JXG.Board#create
with type "circle3d".
- Possible parent array combinations are:
-
{JXG.Point} center
{Array} normal
{number} radius
- The center must be given as a JXG.Point (see JXG.providePoints).
The normal vector can be given as an array of three numbers or an array of three functions returning numbers,
and the radius can be given as a number (which will create a circle with a fixed radius) or a function.
If the radius is supplied as a number or the output of a function, its absolute value is taken. When the radius evaluates to NaN, the circle does not display.
- Throws:
- {Exception}
- If the element cannot be constructed with the given parent objects an exception is thrown.
