<brief_description>
Class for importing and exporting glTF files in and out of Godot.
</brief_description>
<description>
GLTFDocument supports reading data from a glTF file, buffer, or Godot scene. This data can then be written to the filesystem, buffer, or used to create a Godot scene.
All of the data in a GLTF scene is stored in the [GLTFState] class. GLTFDocument processes state objects, but does not contain any scene data itself.
GLTFDocument can be extended with arbitrary functionality by extending the [GLTFDocumentExtension] class and registering it with GLTFDocument via [method register_gltf_document_extension]. This allows for custom data to be imported and exported.

<description>
Takes a [PackedByteArray] defining a GLTF and imports the data to the given [GLTFState] object through the [param state] parameter.
[b]Note:[/b] The [param base_path] tells [method append_from_buffer] where to find dependencies and can be empty.

<description>
Takes a path to a GLTF file and imports the data at that file path to the given [GLTFState] object through the [param state] parameter.
[b]Note:[/b] The [param base_path] tells [method append_from_file] where to find dependencies and can be empty.

<return type="void" />
<param index="0" name="extension" type="GLTFDocumentExtension" />
<param index="1" name="first_priority" type="bool" default="false" />
<description>
Registers the given [GLTFDocumentExtension] instance with GLTFDocument. If [param first_priority] is true, this extension will be run first. Otherwise, it will be run last.
[b]Note:[/b] Like GLTFDocument itself, all GLTFDocumentExtension classes must be stateless in order to function properly. If you need to store data, use the [code]set_additional_data[/code] and [code]get_additional_data[/code] methods in [GLTFState] or [GLTFNode].

<method name="unregister_gltf_document_extension" qualifiers="static">
<return type="void" />
<param index="0" name="extension" type="GLTFDocumentExtension" />
<description>
Unregisters the given [GLTFDocumentExtension] instance.

<return type="int" enum="Error" />
<param index="0" name="state" type="GLTFState" />
<param index="1" name="path" type="String" />
<description>
Takes a [GLTFState] object through the [param state] parameter and writes a glTF file to the filesystem.
[b]Note:[/b] The extension of the glTF file determines if it is a .glb binary file or a .gltf file.
