API changes

This version is mainly a bug-fix version, fixed a lot of bugs, and improved a lot of compatibility issues and performances for FBX, Collada, STL, obj, drc, gltf, glb.

Only a few minor API changes.

Added new property in class com.aspose.threed.GltfSaveOptions:

    /**
     * Use external draco encoder to accelerate the draco compression speed.
     */
    public String getExternalDracoEncoder();
    
    /**
     * Use external draco encoder to accelerate the draco compression speed.
     * @param value New value
     */
    public void setExternalDracoEncoder(String value);

Aspose.3D for java 21.4 has twice performance improvement for Draco than old versions, but the Google’s official implementation that was written in C++ is still faster, so we enable user to use external Draco encoder for better performance.

Sample code to use external official encoder to accelerate the compressed GLB generation:

        var mesh = new Sphere();
        var scene = new Scene(mesh);
        var opt = new GltfSaveOptions(FileFormat.GLTF2__BINARY);
        opt.setExternalDracoEncoder("D:\\Github\\draco\\sln\\Release\\draco_encoder.exe");
        opt.setDracoCompression(true);
        scene.save("test.glb", opt);
