CalmGenerator() - jmotion reference

When an object is created, properties are set to default values. CalmGenerator.prototype.paths is set to a list of cubic Bezier curves for each joint orbit.

A cubic Bezier curve has four coordinates: a start point, an end point, and corresponding control points. For example, in the orbit of the right hand "catch-to-throw" has (-90, 10), (-90, 37), (-30, 37), and (-30, 10). A total of 8 Bezier curves (SVGPathElement objects representing them) are set as shown in the table below.

arm	direction	joint	orbit overview
right	catch-to-throw	hand	bottom half of large ellipse from right to left
	catch-to-throw	elbow	bottom half of small ellipse from right to left
	throw-to-catch	hand	top half of large ellipse from left to right
	throw-to-catch	elbow	top half of small ellipse from left to right
left	catch-to-throw	hand	bottom half of large ellipse from left to right
	catch-to-throw	elbow	bottom half of small ellipse from left to right
	throw-to-catch	hand	top half of large ellipse from right to left
	throw-to-catch	elbow	top half of small ellipse from right to left

Note that these are approximate representations of ellipses, not exact ellipses.

Syntax

new CalmGenerator()
new CalmGenerator(resolution)

Parameters

resolution (optional): This is the resolution used when calling calculateOrbits(). This value will be set to CalmGenerator.prototype.resolution as is.; If a value of 0 or less is specified, or if this argument is omitted, it is set to 1.

Examples

const generator = new jmotion.CalmGenerator();

// generator = {
//     "offset": {
//         "left": { "x": 0, "y": -10 },
//         "right": { "x": 0, "y": -10 },
//     },
//     "paths": {
//         "left": [
//             [ path, path ],
//             [ path, path ],
//         ],
//         "right": [
//             [ path, path ],
//             [ path, path ],
//         ],
//     },
//     "resolution": 1,
//     "scale": 1,
//     "width": 1,
