BabylonJS - Disc
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.
- 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.
With the tessellation value, you can get a regular polygon −
The last 2 parameters can be omitted.
