+ * 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

+/**
+ * Creates a cylinder or a cone mesh
+ * * 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 `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).
+ * * 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 : https://www.html5gamedevs.com/topic/17945-creating-a-closed-slice-of-a-cylinder/#comment-106379
+ * * 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 mesh can be set to updatable with the boolean parameter `updatable` (default false) if its internal geometry is supposed to change once created.

+ * Creates a dashed line mesh
+ * * A dashed line mesh is considered as a parametric shape since it has no predefined original shape. Its shape is determined by the passed array of points as an input parameter
+ * * Like every other parametric shape, it is dynamically updatable by passing an existing instance of LineMesh to this static function
+ * * The parameter `points` is an array successive Vector3
+ * * The parameter `dashNb` is the intended total number of dashes (positive integer, default 200)
+ * * The parameter `dashSize` is the size of the dashes relatively the dash number (positive float, default 3)
+ * * The parameter `gapSize` is the size of the gap between two successive dashes relatively the dash number (positive float, default 1)
+ * * The optional parameter `instance` is an instance of an existing LineMesh object to be updated with the passed `points` parameter : https://doc.babylonjs.com/features/featuresDeepDive/mesh/dynamicMeshMorph#lines-and-dashedlines
+ * * The optional parameter `useVertexAlpha` is to be set to `false` (default `true`) when you don't need the alpha blending (faster)
+ * * The optional parameter `material` is the material to use to draw the lines if provided. If not, a default material will be created
+ * * When updating an instance, remember that only point positions can change, not the number of points
+ * * 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 dashed line mesh

+ * * The optional parameter `firstNormal` (Vector3) defines the direction of the first normal of the supplied path. It should be supplied when the path is in the xy plane, and particularly if these sections are straight, because the underlying Path3D object will pick a normal in the xy plane that causes the extrusion to be collapsed into the plane.

+ * Creates lathe mesh.
+ * The lathe is a shape with a symmetry axis : a 2D model shape is rotated around this axis to design the lathe
+ * * The parameter `shape` is a required array of successive Vector3. This array depicts the shape to be rotated in its local space : the shape must be designed in the xOy plane and will be rotated around the Y axis. It's usually a 2D shape, so the Vector3 z coordinates are often set to zero
+ * * The parameter `radius` (positive float, default 1) is the radius value of the lathe
+ * * The parameter `tessellation` (positive integer, default 64) is the side number of the lathe
+ * * The parameter `clip` (positive integer, default 0) is the number of sides to not create without effecting the general shape of the sides
+ * * The parameter `arc` (positive float, default 1) is the ratio of the lathe. 0.5 builds for instance half a lathe, so an opened shape
+ * * The parameter `closed` (boolean, default true) opens/closes the lathe circumference. This should be set to false when used with the parameter "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
+ * * 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 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

+ * Creates a polyhedron mesh
+ * * 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 overrides 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 : https://doc.babylonjs.com/features/featuresDeepDive/materials/using/texturePerBoxFace
+ * * 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
+ * * 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 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 polyhedron mesh

+ * * The parameter `subdivisions` sets the number of subdivisions (positive integer, default 4). The more subdivisions, the more faces on the icosphere whatever its size
+ * * The parameter `flat` (boolean, default true) gives each side its own normals. Set it to false to get a smooth continuous light reflection on the surface
+ * * 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

+/**
+ * # WebGPU Debug Marker Implementation — Problem Statement
+ *
+ * ## Background
+ *
+ * WebGPU exposes `pushDebugGroup` / `popDebugGroup` on two distinct objects:
+ *   - The **render encoder** (`GPUCommandEncoder`), which lives for the lifetime of an entire
+ *     submission (one call to `flushFramebuffer`).
+ *   - The **render pass encoder** (`GPURenderPassEncoder`), which lives only for the duration of
+ *     a single render pass.
+ *
+ * WebGPU requires that every push/pop pair is issued on the **same** object, and that all open
+ * groups are closed before the object ends. Violating either rule is a validation error.
+ *
+ * ## The Core Problem
+ *
+ * From the Babylon.js side, the user calls `_debugPushGroup` / `_debugPopGroup` at arbitrary
+ * points in time — completely independently of whether a render pass is currently active or not.
+ * This creates several mismatched-context scenarios that must be handled transparently.
+ *
+ * ## Scenario 1 — Push on render encoder, pop inside a render pass
+ *
+ *   1. User calls `_debugPushGroup` while no render pass is active → group is pushed on the
+ *      render encoder and recorded in `_debugMarkersEncoderGroups`.
+ *   2. A render pass starts (`_currentRenderPass` becomes non-null).
+ *   3. User calls `_debugPopGroup` while the render pass is active. The pop must logically target
+ *      the render encoder group, but we cannot call `popDebugGroup` on the render encoder while a
+ *      render pass is active (the pass is the live object).
+ *   4. We detect this mismatch because `_debugMarkersPassGroups` is empty (no group was pushed
+ *      during this render pass), so we increment `_debugMarkersPendingEncoderPops` instead of
+ *      issuing the pop immediately.
+ *   5. When the render pass ends (`_endCurrentRenderPass`), `_debugPendingPop` drains the
+ *      `_debugMarkersPendingEncoderPops` counter and issues the deferred pops on the render encoder.
+ *
+ *   **Edge case — deferred pop followed by a render-pass push:** if the user pushes another group
+ *   during the same render pass *after* the deferred pop was recorded, that new group goes into
+ *   `_debugMarkersPassGroups`. When the pass ends, `_debugPopBeforeEndOfEncoder` auto-pops the
+ *   pass-level group, leaving it floating in `_debugMarkersPassGroups`. `_debugPendingPop` then
+ *   pops from `_debugMarkersEncoderGroups` — a separate array that can never contain pass-level
+ *   entries — so the floating pass-level group is preserved intact and will be re-pushed on the
+ *   next render pass by `_debugPushAfterStartOfEncoder`.
+ *
+ * ## Scenario 2 — Push inside a render pass, render pass ends before pop
+ *
+ *   1. User calls `_debugPushGroup` while a render pass is active → group is pushed on the render
+ *      pass encoder and recorded in `_debugMarkersPassGroups`.
+ *   2. The render pass ends (e.g. a new render target is bound) before the user calls
+ *      `_debugPopGroup`. All open render-pass groups must be closed before
+ *      `GPURenderPassEncoder.end()` is called.
+ *   3. `_debugPopBeforeEndOfEncoder` auto-pops every group in `_debugMarkersPassGroups` from the
+ *      render pass encoder. The names remain in `_debugMarkersPassGroups` (the array is not
+ *      cleared) so the logical nesting is preserved and the groups are now "floating".
+ *   4. After the next render pass is created, `_debugPushAfterStartOfEncoder` re-pushes all
+ *      floating pass groups onto it, so that when the user eventually calls `_debugPopGroup`
+ *      there is always a matching push on the current live object.
+ *
+ * ## Scenario 3 — `flushFramebuffer` called mid-frame (multiple times per frame)
+ *
+ *   `flushFramebuffer` submits all recorded GPU commands and creates a brand-new pair of encoders.
+ *   It can be called more than once during a single Babylon.js frame (e.g. for read-back
+ *   operations, multi-view rendering, or explicit flushes). Each call:
+ *   1. Ends the current render pass if any (`_endCurrentRenderPass`), which triggers the
+ *      render-pass auto-pop and pending-pop handling described above.
+ *   2. Calls `_debugPopBeforeEndOfEncoder` to close every still-open group on the render encoder
+ *      before it is finalised and submitted. Only encoder-level groups (`_debugMarkersEncoderGroups`)
+ *      are popped from the encoder; pass-level groups (`_debugMarkersPassGroups`) are already
+ *      floating after step 1 and were never pushed on the encoder, so they are left alone.
+ *   3. Creates new `_uploadEncoder` / `_renderEncoder` instances.
+ *   4. Calls `_debugPushAfterStartOfEncoder` to re-open the encoder-level groups on the new render
+ *      encoder, so the user's subsequent pops still find a matching push.
+ *   When `flushFramebuffer` is called from `endFrame` (the last flush of the frame), both arrays
+ *   are cleared (`_debugMarkersEncoderGroups` and `_debugMarkersPassGroups`) because any groups
+ *   still open at end-of-frame are considered abandoned.
+ *
+ * ## State variables
+ *
+ *   - `_debugMarkersEncoderGroups` — names of groups currently open on the render encoder (pushed
+ *     while no render pass was active). These are re-pushed on the new render encoder after each
+ *     mid-frame flush.
+ *   - `_debugMarkersPassGroups` — names of groups pushed while a render pass was active. While a
+ *     pass is live these are open on that pass encoder. When a pass ends they become "floating" —
+ *     auto-popped from the finished pass but not yet on any GPU object — and remain here until the
+ *     next render pass starts and `_debugPushAfterStartOfEncoder` re-opens them on it.
+ *   - `_debugMarkersPendingEncoderPops` — count of user pops that arrived while a render pass was
+ *     active but whose matching push lived on the render encoder. These pops are deferred and
+ *     replayed on the render encoder once the render pass ends.

+ *
+ * This class wraps the Draco decoder module.
+ *
+ * By default, the configuration points to a copy of the Draco decoder files for glTF from the Babylon.js cdn https://cdn.babylonjs.com/draco_wasm_wrapper_gltf.js.
+ *
+ * To update the configuration, use the following code:
+ * ```javascript
+ *     DracoDecoder.DefaultConfiguration = {
+ *          wasmUrl: "<url to the WebAssembly library>",
+ *          wasmBinaryUrl: "<url to the WebAssembly binary>",
+ *          fallbackUrl: "<url to the fallback JavaScript library>",
+ *     };
+ * ```
+ *
+ * Draco has two versions, one for WebAssembly and one for JavaScript. The decoder configuration can be set to only support WebAssembly or only support the JavaScript version.
+ * Decoding will automatically fallback to the JavaScript version if WebAssembly version is not configured or if WebAssembly is not supported by the browser.
+ * Use `DracoDecoder.DefaultAvailable` to determine if the decoder configuration is available for the current context.
+ *
+ * To decode Draco compressed data, get the default DracoDecoder object and call decodeMeshToGeometryAsync:
+ * ```javascript
+ *     var geometry = await DracoDecoder.Default.decodeMeshToGeometryAsync(data);
+ * ```

+ * @experimental This class is subject to change.
+ *
+ * Draco Encoder (https://google.github.io/draco/)
+ *
+ * This class wraps the Draco encoder module.
+ *
+ * By default, the configuration points to a copy of the Draco encoder files from the Babylon.js cdn https://cdn.babylonjs.com/draco_encoder_wasm_wrapper.js.
+ *
+ * To update the configuration, use the following code:
+ * ```javascript
+ *     DracoEncoder.DefaultConfiguration = {
+ *          wasmUrl: "<url to the WebAssembly library>",
+ *          wasmBinaryUrl: "<url to the WebAssembly binary>",
+ *          fallbackUrl: "<url to the fallback JavaScript library>",
+ *     };
+ * ```
+ *
+ * Draco has two versions, one for WebAssembly and one for JavaScript. The encoder configuration can be set to only support WebAssembly or only support the JavaScript version.
+ * Decoding will automatically fallback to the JavaScript version if WebAssembly version is not configured or if WebAssembly is not supported by the browser.
+ * Use `DracoEncoder.DefaultAvailable` to determine if the encoder configuration is available for the current context.
+ *
+ * To encode Draco compressed data, get the default DracoEncoder object and call encodeMeshAsync:
+ * ```javascript
+ *     var dracoData = await DracoEncoder.Default.encodeMeshAsync(mesh);
+ * ```
+ *
+ * Currently, DracoEncoder only encodes to meshes. Encoding to point clouds is not yet supported.
+ *
+ * Only position, normal, color, and UV attributes are supported natively by the encoder. All other attributes are treated as generic. This means that,
+ * when decoding these generic attributes later, additional information about their original Babylon types will be needed to interpret the data correctly.
+ * You can use the return value of `encodeMeshAsync` to source this information, specifically the `attributes` field. E.g.,
+ * ```javascript
+ *    var dracoData = await DracoEncoder.Default.encodeMeshAsync(mesh);
+ *    var meshData = await DracoDecoder.Default.decodeMeshToMeshDataAsync(dracoData.data, dracoData.attributes);
+ * ```
+ *
+ * By default, DracoEncoder will encode all available attributes of the mesh. To exclude specific attributes, use the following code:
+ * ```javascript
+ *    var options = { excludedAttributes: [VertexBuffer.MatricesIndicesKind, VertexBuffer.MatricesWeightsKind] };
+ *    var dracoData = await DracoDecoder.Default.encodeMeshAsync(mesh, options);
+ * ```

+\param csZBuffer The camera-space Z buffer
+\param csZBufferSize Dimensions of csZBuffer
+\param csZThickness Camera space csZThickness to ascribe to each pixel in the depth buffer
+\param nearPlaneZ Positive number. Doesn't have to be THE actual near plane,just a reasonable value

+\param farPlaneZ The far plane for the camera. Used when screen-space depth is enabled.
+\param stride Step in horizontal or vertical pixels between samples. This is a var because: f32 integer math is slow on GPUs,but should be set to an integer>=1
+\param jitterFraction Number between 0 and 1 for how far to bump the ray in stride units
+to conceal banding artifacts,plus the stride ray offset.
+\param maxSteps Maximum number of iterations. Higher gives better images but may be slow
+\param maxRayTraceDistance Maximum camera-space distance to trace before returning a miss
+\param selfCollisionNumSkip Number of steps to skip at start when raytracing to avar self: voidnull collisions.
+1 is a reasonable value,depending on the scene you may need to set this value to 2
