The parameter \"diameterBottom\" can't be zero.\n * * The parameter `tessellation` sets the number of cylinder sides (positive integer, default 24). Set it to 3 to get a prism for instance.\n * * The parameter `subdivisions` sets the number of rings along the cylinder height (positive integer, default 1).\n * * The parameter `hasRings` (boolean, default false) makes the subdivisions independent from each other, so they become different faces.\n * * The parameter `enclose` (boolean, default false) adds two extra faces per subdivision to a sliced cylinder to close it around its height axis.\n * * 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).\n * * The parameter `arc` (float, default 1) is the ratio (max 1) to apply to the circumference to slice the cylinder.\n * * 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).\n * * 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\n * * Now, if the cylinder has 5 independent subdivisions (hasRings = true), n equals : top face + 5 stripe surfaces + bottom face = 2 + 5 = 7\n * * 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\n * * 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.\n * * If `enclose` is false, a ring surface is one element.\n * * If `enclose` is true, a ring surface is 3 successive elements in the array : the tubular surface, then the two closing faces.\n * * 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\n * * You can also set the mesh side orientation with the values : BABYLON.Mesh.FRONTSIDE (default), BABYLON.Mesh.BACKSIDE or BABYLON.Mesh.DOUBLESIDE\n * * 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).

Please refer to the type sheet in the tutorial to choose the wanted type\n * * The parameter `size` (positive float, default 1) sets the polygon size\n * * You can overwrite the `size` on each dimension bu using the parameters `sizeX`, `sizeY` or `sizeZ` (positive floats, default to `size` value)\n * * You can build other polyhedron types than the 15 embbeded ones by setting the parameter `custom` (`polyhedronObject`, default null). If you set the parameter `custom`, this overrides the parameter `type`\n * * A `polyhedronObject` is a formatted javascript object. You'll find a full file with pre-set polyhedra here : https://github.com/BabylonJS/Extensions/tree/master/Polyhedron\n * * You can set the color and the UV of each side of the polyhedron with the parameters `faceColors` (Color4, default `(1, 1, 1, 1)`) and faceUV (Vector4, default `(0, 0, 1, 1)`)\n * * To understand how to set `faceUV` or `faceColors`, please read this by considering the right number of faces of your polyhedron, instead of only 6 for the box : https://doc.babylonjs.com/features/featuresDeepDive/materials/using/texturePerBoxFace\n * * The parameter `flat` (boolean, default true). If set to false, it gives the polyhedron a single global face, so less vertices and shared normals. In this case, `faceColors` and `faceUV` are ignored\n * * You can also set the mesh side orientation with the values : BABYLON.Mesh.FRONTSIDE (default), BABYLON.Mesh.BACKSIDE or BABYLON.Mesh.DOUBLESIDE\n * * 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).

The parameter \"diameterBottom\" can't be zero.\n * * The parameter `tessellation` sets the number of cylinder sides (positive integer, default 24). Set it to 3 to get a prism for instance.\n * * The parameter `subdivisions` sets the number of rings along the cylinder height (positive integer, default 1).\n * * The parameter `hasRings` (boolean, default false) makes the subdivisions independent from each other, so they become different faces.\n * * The parameter `enclose` (boolean, default false) adds two extra faces per subdivision to a sliced cylinder to close it around its height axis.\n * * 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).\n * * The parameter `arc` (float, default 1) is the ratio (max 1) to apply to the circumference to slice the cylinder.\n * * 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).\n * * 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\n * * Now, if the cylinder has 5 independent subdivisions (hasRings = true), n equals : top face + 5 stripe surfaces + bottom face = 2 + 5 = 7\n * * 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\n * * 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.\n * * If `enclose` is false, a ring surface is one element.\n * * If `enclose` is true, a ring surface is 3 successive elements in the array : the tubular surface, then the two closing faces.\n * * 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\n * * You can also set the mesh side orientation with the values : BABYLON.Mesh.FRONTSIDE (default), BABYLON.Mesh.BACKSIDE or BABYLON.Mesh.DOUBLESIDE\n * * 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).

Please refer to the type sheet in the tutorial to choose the wanted type\n * * The parameter `size` (positive float, default 1) sets the polygon size\n * * You can overwrite the `size` on each dimension bu using the parameters `sizeX`, `sizeY` or `sizeZ` (positive floats, default to `size` value)\n * * You can build other polyhedron types than the 15 embbeded ones by setting the parameter `custom` (`polyhedronObject`, default null). If you set the parameter `custom`, this overrides the parameter `type`\n * * A `polyhedronObject` is a formatted javascript object. You'll find a full file with pre-set polyhedra here : https://github.com/BabylonJS/Extensions/tree/master/Polyhedron\n * * You can set the color and the UV of each side of the polyhedron with the parameters `faceColors` (Color4, default `(1, 1, 1, 1)`) and faceUV (Vector4, default `(0, 0, 1, 1)`)\n * * To understand how to set `faceUV` or `faceColors`, please read this by considering the right number of faces of your polyhedron, instead of only 6 for the box : https://doc.babylonjs.com/features/featuresDeepDive/materials/using/texturePerBoxFace\n * * The parameter `flat` (boolean, default true). If set to false, it gives the polyhedron a single global face, so less vertices and shared normals. In this case, `faceColors` and `faceUV` are ignored\n * * You can also set the mesh side orientation with the values : BABYLON.Mesh.FRONTSIDE (default), BABYLON.Mesh.BACKSIDE or BABYLON.Mesh.DOUBLESIDE\n * * 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).
