Creating A Cylinder
Cylinder or Cone
The created cylinder has its flat sides parallel to the xz plane, with its origin at the center of the vertical line of symmetry. If you set diameterTop to zero, you get a cone instead of a cylinder. With different values for diameterTop and diameterBottom, you get a truncated cone.
MeshBuilder
Usage :
import { MeshBuilder } from "@babylonjs/core/Meshes/meshBuilder";const cone = MeshBuilder.CreateCylinder("cone", options, scene); //scene is optional and defaults to the current scene| option | value | default value |
|---|---|---|
| height | (number) height of the cylinder | 2 |
| diameterTop | (number) diameter of the top cap, can be zero to create a cone, overwrites the diameter option | 1 |
| diameterBottom | (number) diameter of the bottom cap, can't be zero, overwrites the diameter option | 1 |
| diameter | (number) diameter of both caps | 1 |
| tessellation | (number) number of radial sides | 24 |
| subdivisions | (number) number of rings | 1 |
| faceColors | (Color4[]) array of 3 Color4, 0 : bottom cap, 1 : cylinder tube, 2 : top cap | Color4(1, 1, 1, 1) for each face |
| faceUV | (Vector4[]) array of 3 Vector4, 0 : bottom cap, 1 : cylinder tube, 2 : top cap | UVs(0, 0, 1, 1) for each face |
| arc | (number) ratio of the circumference between 0 and 1 | 1 |
| hasRings | (boolean) makes the subdivisions independent from each other, so they become different faces | false |
| enclose | (boolean) adds two extra faces per subdivision to a sliced cylinder to close it around its height axis | false |
| updatable | (boolean) true if the mesh is updatable | false |
| sideOrientation | (number) side orientation | DEFAULTSIDE |
| frontUVs | (Vector4) ONLY WHEN sideOrientation:BABYLON.Mesh.DOUBLESIDE set | Vector4(0,0, 1,1) |
| backUVs | (Vector4) ONLY WHEN sideOrientation:BABYLON.Mesh.DOUBLESIDE set | Vector4(0,0, 1,1) |

Usage :
import { MeshBuilder } from "@babylonjs/core/Meshes/meshBuilder";const cylinder = MeshBuilder.CreateCylinder("cylinder", { height, diameterTop, diameterBottom, tessellation, subdivisions }, scene);
