- 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.
- </p>

- <p>See the base [page:LineSegments] class for common methods.</p>
- <h3>[method:undefined dispose]()</h3>
- <p>
- Frees the GPU-related resources allocated by this instance. Call this
- method whenever this instance is no longer used in your app.
