<h1>[name]</h1>
<p class="desc">The PolarGridHelper is an object to define polar grids. Grids are two-dimensional arrays of lines.</p>
<h2>Code Example</h2>
<code>
const radius = 10;
const sectors = 16;
const rings = 8;
const divisions = 64;
const helper = new THREE.PolarGridHelper( radius, sectors, rings, divisions );
scene.add( helper );
</code>
<h2>Examples</h2>
<p>
[example:webgl_helpers WebGL / helpers]
</p>
<h2>Constructor</h2>
<h3>[name]( [param:Number radius], [param:Number sectors], [param:Number rings], [param:Number divisions], [param:Color color1], [param:Color color2] )</h3>
<p>
radius -- The radius of the polar grid. This can be any positive number. Default is 10.<br />
sectors -- The number of sectors the grid will be divided into. This can be any positive integer. Default is 16.<br />
rings -- The number of rings. This can be any positive integer. Default is 8.<br />
divisions -- The number of line segments used for each circle. This can be any positive integer that is 3 or greater. Default is 64.<br />
color1 -- The first color used for grid elements. This can be a [page:Color], a hexadecimal value and an CSS-Color name. Default is 0x444444 <br />
color2 -- The second color used for grid elements. This can be a [page:Color], a hexadecimal value and an CSS-Color name. Default is 0x888888
</p>
<p>
Creates a new [name] of radius 'radius' with 'sectors' number of sectors and 'rings' number of rings, where each circle is smoothed into 'divisions' number of line segments. Colors are optional.
