An STL file describes the surface geometry of 3‑D objects and is commonly used for 3‑D printing, rapid prototyping, and engineering simulations. In contrast, USDZ files are ZIP‑based archives that store Universal Scene Description data and are increasingly popular for augmented‑reality (AR) experiences. Converting STL to USDZ enables you to reuse existing 3‑D models in AR‑enabled apps. This article explains how to perform this conversion programmatically in Java.
USDZ to STL Converter – Java API Installation
Aspose.3D for Java provides a comprehensive set of tools for reading, editing, and exporting 3‑D file formats. To start using the library, add the Aspose repository and the aspose-3d dependency to your Maven project.
Repository:
<repositories>
<repository>
<id>AsposeJavaAPI</id>
<name>Aspose Java API</name>
<url>http://repository.aspose.com/repo/</url>

Dependency:
<dependencies>
<dependency>
<groupId>com.aspose</groupId>
<artifactId>aspose-3d</artifactId>
<version>22.4</version>
</dependency>

After updating pom.xml, run mvn clean install to download the library and its transitive dependencies.
Convert STL to USDZ File Programmatically in Java
Follow these three steps to transform an STL model into a USDZ package:
- Load the source STL file with the Scene class.
- Create a
UsdSaveOptionsinstance to specify USDZ export settings. - Call the
savemethod to generate the USDZ file.
The example below demonstrates a complete Java program that reads model.stl and writes model.usdz using Aspose.3D.
