  69043. * Creates a cylinder or a cone mesh
  69044. * * The parameter `height` sets the height size (float) of the cylinder/cone (float, default 2).
  69045. * * The parameter `diameter` sets the diameter of the top and bottom cap at once (float, default 1).
  69046. * * 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.
  69047. * * The parameter `tessellation` sets the number of cylinder sides (positive integer, default 24). Set it to 3 to get a prism for instance.
  69048. * * The parameter `subdivisions` sets the number of rings along the cylinder height (positive integer, default 1).
  69049. * * The parameter `hasRings` (boolean, default false) makes the subdivisions independent from each other, so they become different faces.
  69050. * * The parameter `enclose` (boolean, default false) adds two extra faces per subdivision to a sliced cylinder to close it around its height axis.
  69051. * * The parameter `arc` (float, default 1) is the ratio (max 1) to apply to the circumference to slice the cylinder.
  69052. * * 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).
  69053. * * 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
  69054. * * Now, if the cylinder has 5 independent subdivisions (hasRings = true), n equals : top face + 5 stripe surfaces + bottom face = 2 + 5 = 7
  69055. * * 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
  69056. * * 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.
  69057. * * If `enclose` is false, a ring surface is one element.
  69058. * * If `enclose` is true, a ring surface is 3 successive elements in the array : the tubular surface, then the two closing faces.
  69059. * * 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

  69318. * Creates an custom extruded shape mesh.
  69319. * The custom extrusion is a parametric shape. It has no predefined shape. Its final shape will depend on the input parameters.
  69320. * * The parameter `shape` is a required array of successive Vector3. This array depicts the shape to be extruded in its local space : the shape must be designed in the xOy plane and will be extruded along the Z axis.
  69321. * * The parameter `path` is a required array of successive Vector3. This is the axis curve the shape is extruded along.
  69322. * * The parameter `rotationFunction` (JS function) is a custom Javascript function called on each path point. This function is passed the position i of the point in the path and the distance of this point from the begining of the path
  69323. * * It must returns a float value that will be the rotation in radians applied to the shape on each path point.
  69324. * * The parameter `scaleFunction` (JS function) is a custom Javascript function called on each path point. This function is passed the position i of the point in the path and the distance of this point from the begining of the path
  69325. * * It must returns a float value that will be the scale value applied to the shape on each path point
  69326. * * The parameter `ribbonClosePath` (boolean, default false) forces the extrusion underlying ribbon to close all the paths in its `pathArray`
  69327. * * The parameter `ribbonCloseArray` (boolean, default false) forces the extrusion underlying ribbon to close its `pathArray`
  69328. * * 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
  69329. * * The optional parameter `instance` is an instance of an existing ExtrudedShape object to be updated with the passed `shape`, `path`, `scale` or `rotation` parameters : http://doc.babylonjs.com/tutorials/How_to_dynamically_morph_a_mesh#extruded-shape
  69330. * * Remember you can only change the shape or path point positions, not their number when updating an extruded shape
  69331. * * You can also set the mesh side orientation with the values : BABYLON.Mesh.FRONTSIDE (default), BABYLON.Mesh.BACKSIDE or BABYLON.Mesh.DOUBLESIDE
  69332. * * 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 : http://doc.babylonjs.com/babylon101/discover_basic_elements#side-orientation
  69333. * * The optional parameter `invertUV` (boolean, default false) swaps in the geometry the U and V coordinates to apply a texture
  69334. * * The mesh can be set to updatable with the boolean parameter `updatable` (default false) if its internal geometry is supposed to change once created

  69748. * * The parameter `size` (positive float, default 1) sets the polygon size
  69749. * * You can overwrite the `size` on each dimension bu using the parameters `sizeX`, `sizeY` or `sizeZ` (positive floats, default to `size` value)
  69750. * * 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`
  69751. * * 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
  69752. * * 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)`)
  69753. * * 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
  69754. * * 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
  69755. * * You can also set the mesh side orientation with the values : BABYLON.Mesh.FRONTSIDE (default), BABYLON.Mesh.BACKSIDE or BABYLON.Mesh.DOUBLESIDE
  69756. * * 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).

  70060. *
  70061. * **Encoder**
  70062. *
  70063. * The encoder is not currently implemented.
  70064. *
  70065. * **Decoder**
  70066. *
  70067. * 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.
  70068. *
  70069. * To update the configuration, use the following code:
  70070. * ```javascript
  70071. * BABYLON.DracoCompression.Configuration = {
  70072. * decoder: {
  70073. * wasmUrl: "<url to the WebAssembly library>",
  70074. * wasmBinaryUrl: "<url to the WebAssembly binary>",
  70075. * fallbackUrl: "<url to the fallback JavaScript library>",
  70076. * }
  70077. * };
  70078. * ```
  70079. *
  70080. * 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.
  70081. * Decoding will automatically fallback to the JavaScript version if WebAssembly version is not configured or if WebAssembly is not supported by the browser.
  70082. * Use `BABYLON.DracoCompression.DecoderAvailable` to determine if the decoder is available for the current session.
  70083. *
  70084. * To decode Draco compressed data, create a DracoCompression object and call decodeMeshAsync:
  70085. * ```javascript
  70086. * var dracoCompression = new BABYLON.DracoCompression();
  70087. * var vertexData = await dracoCompression.decodeMeshAsync(data, {
  70088. * [BABYLON.VertexBuffer.PositionKind]: 0
