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 Aspose.ThreeD.Formats.GltfSaveOptions:

    /// <summary>
    /// Use external draco encoder to accelerate the draco compression speed.
    /// </summary>
    /// <remarks>
    /// Aspose.3D will create new sub process to encode the mesh to the draco format, use it at your own risk. 
    /// </remarks>
    public string ExternalDracoEncoder { get; set; }

Aspose.3D for .net 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.ExternalDracoEncoder = @"D:\Github\draco\sln\Release\draco_encoder.exe";
    opt.DracoCompression = true;
    scene.Save("test.glb", opt);
