<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 radials = 16;
|
|
const circles = 8;
|
|
const divisions = 64;
|
|
|
|
const helper = new THREE.PolarGridHelper( radius, radials, circles, divisions );
|
|
scene.add( helper );
|
|
</code>

<h2>Constructor</h2>
|
|
|
|
<h3>[name]( [param:Number radius], [param:Number radials], [param:Number circles], [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 />
|
|
radials -- The number of radial lines. This can be any positive integer. Default is 16.<br />
|
|
circles -- The number of circles. 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 'radials' number of radials and 'circles' number of circles, where each circle is smoothed into 'divisions' number of line segments. Colors are optional.
