Asset-Management.DRACOLoader2

Hierarchy

• DRACOLoader

  ↳ DRACOLoader2

Implements

• ILoader<BufferGeometry, Mesh | undefined>

Properties

LIB_CDN_PATH

▪ Static LIB_CDN_PATH: string = 'https://cdn.jsdelivr.net/gh/google/[email protected]/javascript/'

---

LibraryValueMap

▪ Static LibraryValueMap: Record<string, any> = {}

This is a hack to allow bundling the draco decoder js file with your app source See DRACOLoader2.SetDecoderJsString for example

---

encoderPending

• encoderPending: null | Promise<any> = null

---

encoderConfig

• encoderConfig: any

---

isDRACOLoader2

• Readonly isDRACOLoader2: true

Methods

SetDecoderJsString

▸ Static SetDecoderJsString(jsString): void

Set the decoder js string Sample for how to set LibraryValueMap This is useful for bundling the draco decoder js file with your app source

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)

Parameters

Name	Type	Description
jsString	string	the contents of draco_decoder.js file

Returns

void

---

transform

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

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

Parameters

Name	Type
res	BufferGeometry<NormalBufferAttributes, BufferGeometryEventMap>
_	AnyOptions

Returns

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