Loading Data

Loading Data

You can load data into the speckle viewer virtually from any source as long as you provide an appropriate loader suite.

Speckle Data

The viewer comes with a builtin speckle loader. Here’s an example of how to get things going:

const urls = await UrlHelper.getResourceUrls(
  'https://app.speckle.systems/projects/7591c56179/models/32213f5381'
)
for (const url of urls) {
  const loader = new SpeckleLoader(viewer.getWorldTree(), url, '')
  /** Load the speckle data */
  await viewer.loadObject(loader, true)
}

Other Data Sources

By creating your own loaders you can load data from various input sources. The viewer library only come with a barebones OBJ loader in addition to the speckle loader.

const objUrl: string = '<your OBJ resource URL>'
/** Create a loader for the .obj data */
const loader = new ObjLoader(viewer.getWorldTree(), objUrl)
/** Load the obj data */
await viewer.loadObject(loader, true)

Alternatively, you can load the OBJ from an OBJ file contents as string or ArrayBuffer

const objData: string | ArrayBuffer = '<your OBJ resource data>'
/** Create a loader for the .obj data */
const loader = new ObjLoader(viewer.getWorldTree(), '<user defined id>', objData)
/** Load the obj data */
await viewer.loadObject(loader, true)
