geom-revolve v2.0.2

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.
