GLB to FBX in Java

How to convert GLB to FBX using Java REST API

[GLB][1], a binary version of glTF (GL Transmission Format), efficiently transmits 3D models in applications. It is popular in web‑based environments because of its compact size and fast loading. In contrast, [FBX][2] (Filmbox) is a versatile format that supports high‑quality 3D models with textures, animations, and lighting. It is widely used in Autodesk Maya, Unity, and other professional tools. Converting GLB to FBX is therefore essential for workflows that need advanced 3D design capabilities and cross‑platform compatibility, allowing designers and developers to work seamlessly across different platforms.

3D Files Processing API

[Aspose.3D Cloud SDK for Java][3] provides a powerful and flexible platform for converting GLB to FBX, making 3D file manipulation seamless and efficient. With its support for multiple file formats, including GLB, FBX, [OBJ][17], and others, [Aspose.3D Cloud][18] SDK simplifies the conversion process while maintaining the quality of textures, animations, and lighting.

Installation and Configuration

The latest version of the Java REST API is available for download under the [release section][19]. Alternatively, you can add the API directly to your Java project via Maven repository.

<dependencies>
    <dependency>
        <groupId>com.aspose</groupId>
        <artifactId>aspose-3d-cloud</artifactId>
        <version>20.5</version>
    </dependency>
</dependencies>

After the installation, you need to obtain your client credentials from [cloud dashboard][4]. In case you do not have an existing account, simply create a free account by following the instructions specified in the [quick start][5] article.

Convert GLB to FBX in Java

In this section, we explore how to use the API in a Java application to transform complex 3D models without installing third‑party software.

ThreeDCloudApi threeDCloudApi  = new ThreeDCloudApi("client_credentials", clientID, clientSecret);

create an instance of ThreeDCloudApi by passing the Client ID and Client Secret details as arguments.

var response = threeDCloudApi.postConvertByFormat(name, "fbx", "myResultant.fbx", folder, true, storage);

Call the [PostConvertByFormat][6] API to perform the GLB to FBX format.

The sample GLB file used in the above example can be downloaded from [Wolf-Blender-2.82a.glb][16].

  • The Cloud SDK supports the following FBX file codes. fbx7200ascii, fbx7200binary, fbx7300ascii, fbx7300binary, fbx7400ascii, fbx7400binary, fbx7500ascii, fbx7500binary

GLB to FBX Online using cURL Commands

To convert GLB to FBX using Aspose.3D Cloud and cURL commands, you can leverage the powerful features of Aspose.3D’s cloud‑based REST API. The process is simple and requires no local installations. We can send HTTP requests using cURL to perform the conversion directly in the cloud, making it efficient and scalable.

The first step in this approach is to generate a JWT access token based on Client ID and Client Secret details.

curl -v "https://api.aspose.cloud/connect/token" \
-X POST \
-d "grant_type=client_credentials&client_id=XXXXXX-XXXXXX-XXXXXX-bff4-f5a14a4b6466&client_secret=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX" \
-H "Content-Type: application/x-www-form-urlencoded" \
-H "Accept: application/json"

Now, we need to execute the following cURL command, which calls [PostConvertByFormat][6] API to perform the GLB to FBX conversion.

curl -v "https://api.aspose.cloud/v3.0/3d/saveas/{sourceFile}&newformat=fbx7200binary&newfilename
