/**
 * Creates a ribbon mesh. The ribbon is a parametric shape.  It has no predefined shape. Its final shape will depend on the input parameters
 * * The parameter `pathArray` is a required array of paths, what are each an array of successive Vector3. The pathArray parameter depicts the ribbon geometry
 * * The parameter `closeArray` (boolean, default false) creates a seam between the first and the last paths of the path array
 * * The parameter `closePath` (boolean, default false) creates a seam between the first and the last points of each path of the path array
 * * The parameter `offset` (positive integer, default : rounded half size of the pathArray length), is taken in account only if the `pathArray` is containing a single path
 * * It's the offset to join the points from the same path. Ex : offset = 10 means the point 1 is joined to the point 11
 * * The optional parameter `instance` is an instance of an existing Ribbon object to be updated with the passed `pathArray` parameter : https://doc.babylonjs.com/features/featuresDeepDive/mesh/dynamicMeshMorph#ribbon
 * * 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 optional parameter `invertUV` (boolean, default false) swaps in the geometry the U and V coordinates to apply a texture
 * * The parameter `uvs` is an optional flat array of `Vector2` to update/set each ribbon vertex with its own custom UV values instead of the computed ones
 * * The parameters `colors` is an optional flat array of `Color4` to set/update each ribbon vertex with its own custom color values
 * * Note that if you use the parameters `uvs` or `colors`, the passed arrays must be populated with the right number of elements, it is to say the number of ribbon vertices. Remember that if you set `closePath` to `true`, there's one extra vertex per path in the geometry
 * * Moreover, you can use the parameter `color` with `instance` (to update the ribbon), only if you previously used it at creation time
 * * 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 ribbon mesh
 * @see https://doc.babylonjs.com/features/featuresDeepDive/mesh/creation/param/ribbon_extra
