  69923. * * The parameter `subdivisions` sets the number of rings along the cylinder height (positive integer, default 1).
  69924. * * The parameter `hasRings` (boolean, default false) makes the subdivisions independent from each other, so they become different faces.

  69928. * * 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
  69929. * * Now, if the cylinder has 5 independent subdivisions (hasRings = true), n equals : top face + 5 stripe surfaces + bottom face = 2 + 5 = 7
  69930. * * 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
  69931. * * 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.
  69932. * * If `enclose` is false, a ring surface is one element.
  69933. * * If `enclose` is true, a ring surface is 3 successive elements in the array : the tubular surface, then the two closing faces.

  70930. *
  70931. * **Encoder**
  70932. *
  70933. * The encoder is not currently implemented.
  70934. *
  70935. * **Decoder**
  70936. *
  70937. * By default, the configuration points to a copy of the Draco decoder files for glTF from the babylon.js preview cdn https://preview.babylonjs.com/draco_wasm_wrapper_gltf.js.
  70938. *
  70939. * To update the configuration, use the following code:
  70940. * ```javascript
  70941. * BABYLON.DracoCompression.Configuration = {
  70942. * decoder: {
  70943. * wasmUrl: "<url to the WebAssembly library>",
  70944. * wasmBinaryUrl: "<url to the WebAssembly binary>",
  70945. * fallbackUrl: "<url to the fallback JavaScript library>",
  70946. * }
  70947. * };
  70948. * ```
  70949. *
  70950. * Draco has two versions, one for WebAssembly and one for JavaScript. The decoder configuration can be set to only support Webssembly or only support the JavaScript version.
  70951. * Decoding will automatically fallback to the JavaScript version if WebAssembly version is not configured or if WebAssembly is not supported by the browser.
  70952. * Use `BABYLON.DracoCompression.DecoderAvailable` to determine if the decoder is available for the current session.
  70953. *
  70954. * To decode Draco compressed data, create a DracoCompression object and call decodeMeshAsync:
  70955. * ```javascript
  70956. * var dracoCompression = new BABYLON.DracoCompression();
  70957. * var vertexData = await dracoCompression.decodeMeshAsync(data, {
  70958. * [BABYLON.VertexBuffer.PositionKind]: 0
