glTF Reader

The glTF Reader provides access to visualization data stored within a particular glTF file. A file does not need to have a particular extension to be read correctly by HOOPS Exchange; however, the file extensions of glTF files that you can expect to be loaded by HOOPS Exchange are:

  • .gltf
  • .glb

Our readers are updated to the latest released version within 90 days of the release of the authoring software. You can see the exact version supported in the current release here.
