         * 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 `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 : http://www.html5gamedevs.com/topic/17945-creating-a-closed-slice-of-a-cylinder/#comment-106379

         * Creates a tube mesh.
         * The tube is a parametric shape :  http://doc.babylonjs.com/tutorials/Parametric_Shapes.  It has no predefined shape. Its final shape will depend on the input parameters.
         *
         * tuto : http://doc.babylonjs.com/tutorials/Mesh_CreateXXX_Methods_With_Options_Parameter#tube
         * The parameter `path` is a required array of successive Vector3. It is the curve used as the axis of the tube.
         * The parameter `radius` (positive float, default 1) sets the tube radius size.
         * The parameter `tessellation` (positive float, default 64) is the number of sides on the tubular surface.
         * The parameter `radiusFunction` (javascript function, default null) is a vanilla javascript function. If it is not null, it overwrittes the parameter `radius`.
         * This function is called on each point of the tube path and is passed the index `i` of the i-th point and the distance of this point from the first point of the path.
         * It must return a radius value (positive float) :
         * ```javascript
         * var radiusFunction = function(i, distance) {
         *     // do things
         *     return radius; }
         * ```
         * The parameter `arc` (positive float, maximum 1, default 1) is the ratio to apply to the tube circumference : 2 x PI x arc.
         * The parameter `cap` sets the way the extruded shape is capped. Possible values : BABYLON.Mesh.NO_CAP (default), BABYLON.Mesh.CAP_START, BABYLON.Mesh.CAP_END, BABYLON.Mesh.CAP_ALL
         * The optional parameter `instance` is an instance of an existing Tube object to be updated with the passed `pathArray` parameter : http://doc.babylonjs.com/tutorials/How_to_dynamically_morph_a_mesh#tube
         * You can also set the mesh side orientation with the values : BABYLON.Mesh.FRONTSIDE (default), BABYLON.Mesh.BACKSIDE or BABYLON.Mesh.DOUBLESIDE
         * Detail here : http://doc.babylonjs.com/tutorials/02._Discover_Basic_Elements#side-orientation
         * The optional parameter `invertUV` (boolean, default false) swaps in the geometry the U and V coordinates to apply a texture.
         * The mesh can be set to updatable with the boolean parameter `updatable` (default false) if its internal geometry is supposed to change once created.

         * The parameter `type` (positive integer, max 14, default 0) sets the polyhedron type to build among the 15 embbeded types. Please refer to the type sheet in the tutorial
         *  to choose the wanted type.
         * The parameter `size` (positive float, default 1) sets the polygon size.
         * You can overwrite the `size` on each dimension bu using the parameters `sizeX`, `sizeY` or `sizeZ` (positive floats, default to `size` value).
         * 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 overwrittes the parameter `type`.
         * 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
         * 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)`).
         * 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 : http://doc.babylonjs.com/tutorials/CreateBox_Per_Face_Textures_And_Colors
         * 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.
         * You can also set the mesh side orientation with the values : BABYLON.Mesh.FRONTSIDE (default), BABYLON.Mesh.BACKSIDE or BABYLON.Mesh.DOUBLESIDE
         * Detail here : http://doc.babylonjs.com/tutorials/02._Discover_Basic_Elements#side-orientation

            Mapping Texture Coordinates to Cube Map Faces
            Because there are multiple faces, the mapping of texture coordinates to positions on cube map faces
            is more complicated than the other texturing targets.  The EXT_texture_cube_map extension is purposefully
            designed to be consistent with DirectX 7's cube map arrangement.  This is also consistent with the cube
            map arrangement in Pixar's RenderMan package.
            For cube map texturing, the (s,t,r) texture coordinates are treated as a direction vector (rx,ry,rz)
            emanating from the center of a cube.  (The q coordinate can be ignored since it merely scales the vector
            without affecting the direction.) At texture application time, the interpolated per-fragment (s,t,r)
            selects one of the cube map face's 2D mipmap sets based on the largest magnitude coordinate direction
            the major axis direction). The target column in the table below explains how the major axis direction
            maps to the 2D image of a particular cube map target.
    
            major axis
            direction     target                              sc     tc    ma
            ----------    ---------------------------------   ---    ---   ---
            +rx          GL_TEXTURE_CUBE_MAP_POSITIVE_X_EXT   -rz    -ry   rx
            -rx          GL_TEXTURE_CUBE_MAP_NEGATIVE_X_EXT   +rz    -ry   rx
            +ry          GL_TEXTURE_CUBE_MAP_POSITIVE_Y_EXT   +rx    +rz   ry
            -ry          GL_TEXTURE_CUBE_MAP_NEGATIVE_Y_EXT   +rx    -rz   ry
            +rz          GL_TEXTURE_CUBE_MAP_POSITIVE_Z_EXT   +rx    -ry   rz
            -rz          GL_TEXTURE_CUBE_MAP_NEGATIVE_Z_EXT   -rx    -ry   rz
    
            Using the sc, tc, and ma determined by the major axis direction as specified in the table above,
            an updated (s,t) is calculated as follows
            s   =   ( sc/|ma| + 1 ) / 2
            t   =   ( tc/|ma| + 1 ) / 2
            If |ma| is zero or very nearly zero, the results of the above two equations need not be defined
            (though the result may not lead to GL interruption or termination).  Once the cube map face's 2D mipmap
            set and (s,t) is determined, texture fetching and filtering proceeds like standard OpenGL 2D texturing.
