Element Detail
Functiongraph3D
A 3D function graph is defined by a function F: R2 → R.

This element has no direct constructor. To create an instance of this element you have to call JXG.Board#create with type "functiongraph3d".
Possible parent array combinations are:
{Function|String} F
{Array} rangeX
{Array} rangeY
  F(x,y) is a function returning a number (or a JessieCode string), rangeX is the array containing lower and upper bound for the range of x, rangeY is the array containing lower and upper bound for the range of y.

Throws:
{Exception}
  If the element cannot be constructed with the given parent objects an exception is thrown.

Examples:

    var box = [-5, 5];
    var view = board.create('view3d',
        [
            [-6, -3], [8, 8],
            [box, box, box]
        ],
        {
            xPlaneRear: {visible: false},
            yPlaneRear: {visible: false},
        });

    // Function F to be plotted
    var F = (x, y) => Math.sin(x * y / 4);

    // 3D surface
    var c = view.create('functiongraph3d', [
        F,
        box, // () => [-s.Value()*5, s.Value() * 5],
        box, // () => [-s.Value()*5, s.Value() * 5],
    ], {
        strokeWidth: 0.5,
        stepsU: 70,
        stepsV: 70
    });
