Geom.ellipse()¶

Description¶

A 2D ellipse or sector of the ellipse is constructed in the XOY plane, with angles specified in degrees, and the center of the figure at (0,0,0).

Syntax¶

JS

Geom.ellipse(majorRadius: Number, minorRadius: Number) -> Shape
Geom.ellipse(majorRadius: Number, minorRadius: Number, angle1: Number, angle2: Number) -> Shape

Parameters¶

Parameter	Type	Description
`majorRadius`	`Number`	The first radius of the ellipse.
`minorRadius`	`Number`	The second radius of the ellipse.
`angle1`	`Number`	The starting angle of the sector of the ellipse in degrees within (0°, 360°).
`angle2`	`Number`	The ending angle of the sector of the ellipse in degrees within (0°, 360°).

Note

When setting parameters for constructing an ellipse, the value of majorRadius (length of the major semi-axis) must be greater than or equal to the value of minorRadius (length of the minor semi-axis).

Return value¶

Type	Description
`Shape`	An object of type `Shape`, an ellipse or sector of the ellipse.

Example¶

JS
let s1 = Geom.ellipse(100, 200);
console.info(s1); // output:
let s2 = Geom.ellipse(100, 200, 0, 90);
console.info(s2); // output:
