BabylonJS - Disc

Quiz

In this section, we will learn how to create a Disc.

Syntax

var disc = BABYLON.Mesh.CreateDisc("disc", 5, 30, scene, false, BABYLON.Mesh.DEFAULTSIDE);

Parameters

Name − This is the name of the disc.
Radius − This is the radius of the disc.
Tessellation − This refers to the tiling of a plane using one or more geometric shapes.

With the tessellation value, you can get a regular polygon −

3 gives a triangle
4 gives a square
5 gives a pentagon
6 gives a hexagon
7 gives a heptagon
8 gives an octagon, and so on

Scene − This is the scene to attach the mesh.
Boolean − This is updatable; by default, it is false.
Defaultside − This is the optional side orientation.

The last 2 parameters can be omitted.
