Failure to open very large FBX Files

I’m attempting to open many large fbx files, but I have noticed that the three largest all immediately throw an exception in the following line:

new Scene( s );

The exception:
Aspose.ThreeD.ImportException
Message: “Cannot open this file”

I was attempting this with files of the following size:
4GB (Failed)
3.2GB (Failed)
2.2GB (Failed)
1.6GB (Successful)

The project is running with Platform set to x64

@bortos

Thank you for contacting support.

Would you please share the 2.2 GB file by uploading it to Google Drive, Dropbox etc so that we may try to reproduce and investigate it in our environment. Before sharing requested data, please ensure using Aspose.3D for .NET 18.8 in your environment.

Hi Farhan

I was able to reproduce the error by generating a large scene with many cubes, saving it, and them attempting to load it.

        Scene scene = new Scene();

        for( int i = 0; i < 800000; i++ )
        {
            var c = scene.RootNode.CreateChildNode( "Fred" + i, new Box( 1, 1, 1 ) );
            c.Transform.Translation = Vector3.ZAxis * i * 3;
        }

        string fileName = "large fbx test.fbx";
        using ( var fs = File.Create(fileName) )
        {
            scene.Save( fs, FileFormat.FBX7500Binary );
        }

        // Throws exception here
        Scene openScene = new Scene( fileName );

Hi

Just curious if I can expect a version release any time soon on with THREEDNET-419 and THREEDNET-423 resolved?

Thanks

@bortos

Thank you for getting back to us.

Please note that the tickets THREEDNET-419 and THREEDNET-423 have been resolved for Aspose.3D for .NET 18.9 for which the tentative date of release is first week of September 2018. We will notify you as soon as the product will be released.

The issues you have found earlier (filed as THREEDNET-419) have been fixed in this update.

Hi

Although my first code snippet now works in 18.9, the problem still exists for the largest file I am working with.

The file is 4,074,833 KB.

The following test reproduces the issue:

    [ Test ]
    public void Aspose_Scene_CanOpenVeryLargeScene()
    {
        Scene scene = new Scene();

        for( int i = 0; i < 1400000; i++ )
        {
            var c = scene.RootNode.CreateChildNode( "Fred" + i, new Box( 1, 1, 1 ) );
            c.Transform.Translation = Vector3.ZAxis * i;
        }

        string temporaryFile = Path.Combine( Path.GetTempPath(), Path.ChangeExtension( Path.GetTempFileName(), ".fbx" ) );

        try
        {
            using ( var saveStream = File.OpenWrite( temporaryFile ) )
                scene.Save( saveStream, FileFormat.FBX7500Binary );

            FileInfo fileInfo = new FileInfo( temporaryFile );

            Debug.WriteLine( "Created fbx file with " + fileInfo.Length + " bytes" );
            
            // Throws exception here
            Scene openScene = new Scene();

            using ( var fs = File.OpenRead( temporaryFile ) )
                openScene.Open( fs );
        }
        finally
        {
            File.Delete( temporaryFile );
        }
    }
