Primitive Shapes
The 'primitives' are accessed through the modeling API using the following:
const { cube, ellipse, star } = require('@jscad/modeling').primitives
2D Primitives
| Primitive | Notes |
|---|---|
| const mypath = arc({center: [2, 2], radius: 2, startAngle: Math.PI, endAngle: Math.PI * 2, segments: 64}) | API documentation |
| const myshape = circle({center: [6.5, 6.5], radius: 3.5, startAngle: Math.PI / 2, endAngle: Math.PI, segments: 64}) | User Guide API |
| const myshape = ellipse({center: [6.5, 6.5], radius: [7, 9], startAngle: Math.PI / 2, endAngle: Math.PI, segments: 64}) | API documentation |
| const mypath = line([ [10, 10], [-10, 10] ]) | API documentation |
| const myshape = polygon({ points: [ [10, 11], [0, 11], [5, 20] ], paths: [0, 1, 2]}) | API documentation |
| const myshape = rectangle({center: [6.5, 6.5], size: [10, 20]}) | API documentation |
| const myshape = roundedRectangle({center: [6.5, 6.5], size: [10, 20], roundRadius: 2, segments: 64}) | API documentation |
| const myshape = square({center: [6.5, 6.5], size: 10}) | API documentation |
| const myshape = star({vertices: 8, outerRadius: 10}) /* star with 8/2 density */ | API documentation |
| const myshape = star({vertices: 12, outerRadius: 40, innerRadius: 20}) /* star with given radius */ | API documentation |
