/**
* Creates the VertexData for a cylinder, cone or prism

* * height sets the height (y direction) of the cylinder, optional, default 2
* * diameterTop sets the diameter of the top of the cone, overwrites diameter, optional, default diameter
* * diameterBottom sets the diameter of the bottom of the cone, overwrites diameter, optional, default diameter
* * diameter sets the diameter of the top and bottom of the cone, optional default 1
* * tessellation the number of prism sides, 3 for a triangular prism, optional, default 24
* * subdivisions` the number of rings along the cylinder height, optional, default 1
* * arc a number from 0 to 1, to create an unclosed cylinder based on the fraction of the circumference given by the arc value, optional, default 1
* * faceColors an array of Color3 elements used to set different colors to the top, rings and bottom respectively
* * faceUV an array of Vector4 elements used to set different images to the top, rings and bottom respectively
* * hasRings when true makes each subdivision independently treated as a face for faceUV and faceColors, optional, default false
* * enclose when true closes an open cylinder by adding extra flat faces between the height axis and vertical edges, think cut cake
* * sideOrientation optional and takes the values : Mesh.FRONTSIDE (default), Mesh.BACKSIDE or Mesh.DOUBLESIDE

/**
* Creates a cylinder or a cone mesh
* * The parameter `height` sets the height size (float) of the cylinder/cone (float, default 2).
* * The parameter `diameter` sets the diameter of the top and bottom cap at once (float, default 1).
* * The parameters `diameterTop` and `diameterBottom` overwrite the parameter `diameter` and set respectively the top cap and bottom cap diameter (floats, default 1). The parameter "diameterBottom" can't be zero.
* * The parameter `tessellation` sets the number of cylinder sides (positive integer, default 24). Set it to 3 to get a prism for instance.
* * The parameter `subdivisions` sets the number of rings along the cylinder height (positive integer, default 1).
* * The parameter `hasRings` (boolean, default false) makes the subdivisions independent from each other, so they become different faces.
* * The parameter `enclose` (boolean, default false) adds two extra faces per subdivision to a sliced cylinder to close it around its height axis.
* * The parameter `cap` sets the way the cylinder is capped. Possible values : BABYLON.Mesh.NO_CAP, BABYLON.Mesh.CAP_START, BABYLON.Mesh.CAP_END, BABYLON.Mesh.CAP_ALL (default).
* * The parameter `arc` (float, default 1) is the ratio (max 1) to apply to the circumference to slice the cylinder.
* * You can set different colors and different images to each box side by using the parameters `faceColors` (an array of n Color3 elements) and `faceUV` (an array of n Vector4 elements).
* * The value of n is the number of cylinder faces. If the cylinder has only 1 subdivisions, n equals : top face + cylinder surface + bottom face = 3
* * Now, if the cylinder has 5 independent subdivisions (hasRings = true), n equals : top face + 5 stripe surfaces + bottom face = 2 + 5 = 7
* * Finally, if the cylinder has 5 independent subdivisions and is enclose, n equals : top face + 5 x (stripe surface + 2 closing faces) + bottom face = 2 + 5 * 3 = 17
* * Each array (color or UVs) is always ordered the same way : the first element is the bottom cap, the last element is the top cap. The other elements are each a ring surface.
* * If `enclose` is false, a ring surface is one element.
* * If `enclose` is true, a ring surface is 3 successive elements in the array : the tubular surface, then the two closing faces.
* * Example how to set colors and textures on a sliced cylinder : https://www.html5gamedevs.com/topic/17945-creating-a-closed-slice-of-a-cylinder/#comment-106379
* * You can also set the mesh side orientation with the values : BABYLON.Mesh.FRONTSIDE (default), BABYLON.Mesh.BACKSIDE or BABYLON.Mesh.DOUBLESIDE
* * If you create a double-sided mesh, you can choose what parts of the texture image to crop and stick respectively on the front and the back sides with the parameters `frontUVs` and `backUVs` (Vector4). Detail here : https://doc.babylonjs.com/features/featuresDeepDive/mesh/creation/set#side-orientation
* * The mesh can be set to updatable with the boolean parameter `updatable` (default false) if its internal geometry is supposed to change once created.
* @param name defines the name of the mesh
* @param options defines the options used to create the mesh
* @param scene defines the hosting scene
* @returns the cylinder mesh
* @see https://doc.babylonjs.com/features/featuresDeepDive/mesh/creation/set#cylinder-or-cone
