Convert OBJ to U3D via Java

OBJ to U3D conversion using Java library without any 3D modeling software.

How to Convert OBJ to U3D Using Java

In order to render OBJ to U3D, we’ll use

Aspose.3D for Java

API which is a feature-rich, powerful and easy to use conversion 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.

Steps to Convert OBJ to U3D via Java

Java programmers can easily convert OBJ file to U3D in just a few lines of code.

  1. Load OBJ file via the constructor of Scene class
  2. Create an instance of U3dSaveOptions
  3. Set U3D specific properties for advanced conversion
  4. Call Scene.save method
  5. Pass the output path with U3D file extension & object of U3dSaveOptions

System Requirements

Before running the Java conversion code, 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 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.

    OBJ What is OBJ File Format

    OBJ files are used by Wavefront's Advanced Visualizer application to define and store the geometric objects. Backward and forward transmission of geometric data is made possible through OBJ files. Both polygonal geometry like points, lines, texture vertices, faces and free-form geometry (curves and surfaces) are supported by OBJ format. This format does not support animation or information related to light and position of scenes. An OBJ file is usually an end product of the 3D modeling process generated by a CAD (Computer Aided Design). The default order to store vertices is counter-clockwise avoiding explicit declaration of face normals. Though OBJ files declare scale information in a comment line yet no units have been declared for OBJ coordinates.

    U3D What is U3D File Format

    U3D (Universal 3D) is a compressed file format and data structure for 3D computer graphics. It contains 3D model information such as triangle meshes, lighting, shading, motion data, lines and points with color and structure. The format was accepted as ECMA-363 standard in August 2005. 3D PDF documents support U3D objects embedding and can be viewed in Adobe Reader (version 7 and onwards). U3D format was developed keeping in view the aim to establish a universal standard for three-dimensional data storage and exchange. However, the format finds its main utilization in encoding for 3D PDF rather than being used as an interchange format. Acrobat 3D converts a supported 3D file type to either U3D or PRC upon conversion into the PDF.
