<p><a href="https://www.khronos.org/gltf/" target="_blank" rel="noopener">glTF</a> (GL Transmission Format) is an <a href="https://github.com/KhronosGroup/glTF/tree/main/specification/2.0)" target="_blank" rel="noopener">open format specification</a> whenever possible.

automatically GC-collected when they are no longer referenced, and they require special handling during
the disposal process.</p>
<p><code>GLTFLoader</code> supports the following glTF 2.0 extensions:</p>
<ul>
<li>KHR_draco_mesh_compression</li>
<li>KHR_materials_clearcoat</li>
<li>KHR_materials_dispersion</li>
<li>KHR_materials_ior</li>
