Generate Point Cloud to GLB via C#

Build your own .NET apps to generate point cloud to GLB files using server-side APIs.

How to Generate Point Cloud to GLB File Using C#

In order to generate point cloud to GLB file, we’ll use

Aspose.3D for .NET

API which is a feature-rich, powerful and easy to use API for C# platform to be used with generate point cloud. Open

NuGet

package manager, search for Aspose.3D and install. You may also use the following command from the Package Manager Console.

Package Manager Console Command


PM> Install-Package Aspose.3D

Steps to Generate Point Cloud to GLB via C#

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

  • Load GLB 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 GLB


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

// 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];
        pc.ControlPoints.Add(pt);
    }
}

// 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;
newScene.Save(output,ply);
 
  • About Aspose.3D for .NET API

    Aspose.3D is a CAD and Gameware API to load, modify and convert 3D files. API is a standalone and does not require any any 3D modeling or rendering software. One can easily use API for Discreet3DS, WavefrontOBJ, STL (ASCII, Binary), Universal3D, FBX (ASCII, Binary), Collada, glTF, PLY, GLB, DirectX and more formats.

    GLB What is GLB File Format?

    GLB is the binary file format representation of 3D models saved in the GL Transmission Format (glTF). Information about 3D models such as node hierarchy, cameras, materials, animations and meshes in binary format. This binary format stores the glTF asset (JSON, .bin and images) in a binary blob. It also avoids the issue of increase in file size which happens in case of glTF. GLB file format results in compact file sizes, fast loading, complete 3D scene representation, and extensibility for further development. The format uses model/gltf-binary as MIME type.
