The PolarGridHelper is an object to define polar grids. Grids are two-dimensional arrays of lines.
const radius = 10; const sectors = 16; const rings = 8; const divisions = 64; const helper = new v3d.PolarGridHelper(radius, sectors, rings, divisions); scene.add(helper);

radius — The radius of the polar grid. This can be any positive number. Default is
sectors — The number of sectors the grid will be divided into. This can be any positive integer. Default is
rings — The number of rings. This can be any positive integer. Default is
divisions — The number of line segments used for each circle. This can be any positive integer that is 3 or greater. Default is
color1 — The first color used for grid elements. This can be a Color, a hexadecimal value, or CSS-Color name. Default is
color2 — The second color used for grid elements. This can be a Color, a hexadecimal value, or CSS-Color name. Default is
Creates a new PolarGridHelper 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.
See the base LineSegments class for common methods.
