BabylonJS - Cylinder

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

Syntax

Following is the syntax to create a cylinder −

var cylinder = BABYLON.Mesh.CreateCylinder("cylinder", 3, 3, 3, 6, 1, scene, false, BABYLON.Mesh.DEFAULTSIDE);

Parameters

Consider the following parameters to create a cylinder −

Name − This is the name of the cylinder.
Height − This is the height of the cylinder.
DiamTop − This is the diameter of top.
DiamBottom − This is the diameter of bottom.
Tessellation − This refers to the tiling of a plane using one or more geometric shapes.
HeightSubdivs − This is the height of the cylinder.
Scene − This is the scene to which the cylinder needs to be attached.
Updatable − Incase the shape of the cylinder needs tobe changed, you can set this to true. This is mainly used while morphing.
Side Orientation − It uses BABYLON.Mesh.DEFAULTSIDE as the default option.

            scene.activeCamera.attachControl(canvas);

         var scene = createScene();

            scene.render();
         });

   </body>

Output

A cylinder with top diameter as 0 forms a cone as shown below −
