Generate Point Cloud to GLB via Java

Generate Point Cloud to GLB using Java library without any 3D modeling software.

How to Generate Point Cloud to GLB File Using Java

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

Aspose.3D for Java

API which is a feature-rich, powerful and easy to use point cloud API for Java platform. You can download its latest version directly from

Aspose Maven Repository

and install it within your Maven-based project by adding the following configurations to the pom.xml.


<name>Aspose Java API</name>


<version>version of aspose-3d API</version>

Steps to Generate Point Cloud to GLB via Java

Java programmers can easily generate point cloud to GLB in just a 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 JAVA is supported on all major operating systems. Just make sure that you have the following prerequisites.

  • Microsoft Windows or a compatible OS with Java Runtime Environment for JSP/JSF Application and Desktop Applications.
  • Get latest version of Aspose.3D for Java directly from Maven.

JAVA code to Generate Point Cloud to GLB

//The source file that needs to generate the point cloud and the output file after saving
String file = "template.glb";
String output = "outFile.ply";

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

//Get pointcloud object of Aspose.3D and generate a point cloud
PointCloud pc=new PointCloud();
scene.getRootNode().accept((Node n) ->
        Matrix4 transform=n.evaluateGlobalTransform(true);
        for(Entity entity : n.getEntities())
            if(entity instanceof Geometry){
                Geometry g= (Geometry) entity;
                Merge(pc, g, transform);
            else if(entity instanceof IMeshConvertible){
                IMeshConvertible mc = (IMeshConvertible) entity;
                Mesh mesh=mc.toMesh();
                Merge(pc, mesh, transform);
    return true;

// create an instance of newScene
Scene newScene= new Scene(pc);
PlySaveOptions ply = new PlySaveOptions();
ply.setPointCloud(true);, ply);

//Merge method for generating point clouds
private void Merge(PointCloud pc, Geometry g, Matrix4 transform)
    PointCloud tmp = PointCloud.fromGeometry(g, 10);
    for (int i = 0; i < tmp.getControlPoints().size(); i++)
        Vector4 pt=Matrix4.mul(transform, tmp.getControlPoints().get(i));

    Java 3D Scene Manipulation Library

    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.
