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>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.
