geom-revolve
Create a simplicial complex geometry by revolving a path around Y axis.
Installation
npm install geom-revolve
Usage
import revolve from "geom-revolve";
const path = new Float32Array([
0.0, 0.0, 0.0, 0.1, 0.0, 0.0, 0.2, 0.2, 0.0, 0.3, 0.5, 0.0, 0.3, 0.7, 0.0,
0.1, 0.8, 0.0, 0.1, 1.0, 0.0, 0.0, 1.0, 0.0,
]);
const geometry = revolve(path);
// => { positions: Float32Array(384), cells: Uint32Array(672) }
API
revolve(path, [numSteps], [angle]): geometry
Parameters
- path:
TypedArray | Array | Array<[x, y, z]>
- positions defining the path to revolve. - numSteps:
number
(default:16
) - rotation subdivisions. - angle:
number
(default:Math.PI * 2
) - angle to rotate by.
Returns
geometry: { positions: TypedArray | Array<[x, y, z]>, cells: TypedArray | Array<[x, y, z]> }
- the revolved geometry.
Returned cells will be either Array of Arrays or TypedArray depending on the path data.
