Class Gltf2Exporter

Placeholder method for future glTF2 ArrayBuffer export functionality.

This method is reserved for implementing glTF2 export that returns an ArrayBuffer without triggering a download.

Creates glTF2 BufferViews and Accessors for all geometry and animation data.

This method processes mesh geometry, animation data, and skeletal information to create the necessary buffer views and accessors required for glTF2 format. It handles data deduplication and proper memory layout.

Creates glTF2 materials and textures from Rhodonite materials.

Processes all materials used by mesh entities, converting Rhodonite material properties to glTF2 PBR format. Handles texture extraction, optimization, and proper format conversion including support for various material extensions.

Creates glTF2 nodes representing the scene graph structure.

Converts Rhodonite entities into glTF2 nodes, preserving hierarchical relationships, transformations, and component associations (meshes, cameras, skins). Handles special cases like billboard nodes and blend shape weights.

Initiates download of the exported glTF2 data as a .glb file.

Creates a downloadable .glb file containing the complete glTF2 scene in binary format. Uses browser download API to save the file locally.

Initiates download of the exported glTF2 data as separate .gltf and .bin files.

Creates downloadable .gltf (JSON) and .bin (binary) files representing the complete glTF2 scene in text format with external binary references.

Exports scene data from the Rhodonite system in glTF2 format.

This is the main entry point for glTF2 export functionality. It processes the scene graph, materials, animations, and other data to create a complete glTF2 output in the specified format.

Example

const buffer = await Gltf2Exporter.export('myScene', {
  type: GLTF2_EXPORT_GLB,
  entities: [rootEntity]
});
