Ellipse
A two dimensional shape that surrounds two focal points, such that for all points on the curve, the sum of the two distances to the focal points is a constant.
The radius
determines the size of the ellipsoid about X and Y axis. Ellipsoids can be created at a requested center
. The segments
specify the number of segments to create per full rotation.
Defaults:
- radius : [1, 1]
- center : [0, 0]
- startAngle : 0
- endAngle : PI * 2
- segments: 32
const { ellipse } = require('@jscad/modeling').primitives const myshape = ellipse({radius: [5, 10]}) const myshape = ellipse({radius: [5, 10], center: [5, 5], startAngle: Math.PI / 2, endAngle: Math.PI, segments: 64})
Circle
A two dimensional shape made by drawing a curve that is always the same distance from a center. All points are the same distance from the center.
