StaticLibraryValueMap

_loadLibrary

• _loadLibrary(url: string, responseType: string): Promise<any>

  Parameters

  • url: string
  • responseType: string

  Returns Promise<any>

initDecoder

• initDecoder(): Promise<any>

  Returns Promise<any>

initEncoder

• initEncoder(): Promise<any>

  Returns Promise<any>

preload

• preload(decoder?: boolean, encoder?: boolean): DRACOLoader

  Parameters

  • decoder: boolean = true
  • encoder: boolean = false

  Returns DRACOLoader

transform

• transform(
      res: BufferGeometry,
      _: AnyOptions,
  ):
      | Mesh<
          BufferGeometry<NormalBufferAttributes, BufferGeometryEventMap>,
          Material<MaterialEventMap> | Material<MaterialEventMap>[],
          Object3DEventMap,
      >
      | undefined

  Transform after load, like convert geometry to mesh, etc. for reference see DRACOLoader2 or PLYLoadPlugin

  Parameters

  • res: BufferGeometry

    result of load

  • _: AnyOptions

  Returns
      | Mesh<
          BufferGeometry<NormalBufferAttributes, BufferGeometryEventMap>,
          Material<MaterialEventMap> | Material<MaterialEventMap>[],
          Object3DEventMap,
      >
      | undefined

StaticSetDecoderJsString

• SetDecoderJsString(jsString: string): void

  Set the decoder js string (JS-only build) Sample for how to set LibraryValueMap This is useful for bundling the draco decoder js file with your app source

  If you bundle only the JS build (no wasm), also call dracoLoader.setDecoderConfig({type: 'js'}) on the instance (or the wasm fetch will be attempted and fail). Alternatively use DRACOLoader2.SetDecoderWasmBinary to bundle the wasm build instead.

  Parameters

  • jsString: string

    the contents of draco_decoder.js file

  Returns void

  Example

  First put the draco_decoder.js file in your src folder, then import it in js/ts as a string

  import draco_decoder from './libs/draco_decoder.1.5.6.js?raw' // vite will load this as a string
  // console.log(draco_decoder) // this should be a string with js content
  DRACOLoader2.SetDecoderJsString(draco_decoder)
  Copy

StaticSetDecoderWasmBinary

• SetDecoderWasmBinary(wrapperJs: string, wasmBinary: ArrayBuffer): void

  Set the decoder wasm wrapper js + wasm binary (WASM build) This is useful for bundling the draco wasm decoder with your app source instead of fetching from CDN.

  Parameters

  • wrapperJs: string

    the contents of draco_wasm_wrapper.js file (string)

  • wasmBinary: ArrayBuffer

    the contents of draco_decoder.wasm file (ArrayBuffer)

  Returns void

  Example

  import draco_wasm_wrapper from './libs/draco_wasm_wrapper.1.5.6.js?raw'
  import draco_decoder_wasm from './libs/draco_decoder.1.5.6.wasm?arraybuffer' // or any loader that returns ArrayBuffer
  DRACOLoader2.SetDecoderWasmBinary(draco_wasm_wrapper, draco_decoder_wasm)
  Copy
