Chapter 327: PolarGridHelper

Core Idea

This helper is an object to define polar grids. Grids are two-dimensional arrays of lines.

Code Examples

const radius = 10;
const sectors = 16;
const rings = 8;
const divisions = 64;
const helper = new THREE.PolarGridHelper( radius, sectors, rings, divisions );
scene.add( helper );

• What it demonstrates: Typical usage of PolarGridHelper.
