Steps to Generate Point Cloud to FBX via C#

Aspose.3D makes it easy for the developers to generate point cloud to the FBX file with just few lines of code.

  • Load FBX file via the constructor of Scene class
  • Get pointcloud object of Aspose.3D
  • Create a transform object through the EvaluateGlobalTransform method
  • Generate point cloud using Merge method
  • Call the Scene.Save method with object

System Requirements

Aspose.3D for .NET is supported on all major operating systems. Just make sure that you have the following prerequisites.

  • Microsoft Windows or a compatible OS with .NET Framework, .NET Core, Mono
  • Development environment like Microsoft Visual Studio
  • Aspose.3D for .NET referenced in your project

C# code to Generate Point Cloud to FBX

//The source file that needs to generate the point cloud
string file = "template.fbx";

// create an instance of Scene
Scene scene = new Scene(file);

//Get pointcloud object of Aspose.3D and generate a point cloud
var pc = new PointCloud();
scene.RootNode.Accept((Node n) =>
    if (n.Entities.Count > 0)
        var transform = n.EvaluateGlobalTransform(true);
        foreach (var entity in n.Entities)
            if (entity is Geometry g)
                Merge(pc, g, transform);
            else if (entity is IMeshConvertible mc)
                var mesh = mc.ToMesh();
                Merge(pc, mesh, transform);

    return true;

//Merge method for generating point clouds
private void Merge(PointCloud pc, Geometry g, Matrix4 transform)
    var tmp = PointCloud.FromGeometry(g, 10);
    for (int i = 0; i < tmp.ControlPoints.Count; i++)
        var pt = transform * tmp.ControlPoints[i];

// create an instance of newScene
var newScene = new Scene(pc);

//When saving, you need to create a SaveOptions object of the save format
string output=System.IO.Path.GetTempPath() + Guid.NewGuid().ToString() + ".ply";
PlySaveOptions ply = new PlySaveOptions();
ply.PointCloud = true;

    FBX What is FBX File Format?

    FBX, FilmBox, is a popular 3D file format that was originally developed by Kaydara for MotionBuilder. It was acquired by Autodesk Inc in 2006 and is now one of the main 3D exchange formats as used by many 3D tools. FBX is available in both binary and ASCII file format. The format was established to provided interoperability between digital content creation applications.
