BabylonJS - Ribbon

Quiz

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

Syntax

Following is the syntax to create a Ribbon.

var ribbon = BABYLON.Mesh.CreateRibbon("ribbon", [path1, path2, ..., pathn], false, false, 0, scene, false, BABYLON.Mesh.DEFAULTSIDE);

Parameters

Consider the following parameters to create a ribbon −

Name − The name given to the ribbon.
Path − The array of array of Vector3, the array of paths REQUIRED.
CloseArray − This helps force the ribbon to join its last and first paths.
ClosePath − This helps force each ribbon path to join its last and first points.
Offset − This is used if the pathArray has one path only.
Scene − The scene to which the ribbon will be attached.
Boolean − By default, it is false.In case the ribbon mesh needs to be updated for morhphing, it is set to true.
Mesh.DEFAULTSIDE − This is the side orientation.
