Functiongraph3D

Element

A 3D functiongraph visualizes a map (x, y) → f(x, y). The graph is a Curve3D element. A 3D function graph is defined by a function \[F: {\mathbb R}^2 \to {\mathbb R}.\]

Usage (signatures)

board.create('functiongraph3d', [F, rangeX, rangeY]);

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.

Parameters

Name	Type	Description
`F`	function \| String	The function F(x,y) returns a number (given as JavaScript function or a JessieCode string)
`rangeX`	Array \| function
`rangeY`	Array \| function

Example

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
});

Throws
