Convert OBJ to GLTF via Python

Render OBJ as GLTF without any 3D modeling and rendering software.

How to Convert OBJ to GLTF Using Python

In order to convert OBJ to GLTF, we’ll use

Aspose.3D for Python via .NET

API which is a feature-rich, powerful and easy to use document manipulation and conversion API for Python. Open

NuGet

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

Command line


pip install aspose-3d

Steps to Convert OBJ to GLTF via Python

Python programmers can easily load & convert OBJ files to GLTF in just a few lines of code.

  1. Load OBJ file via the from_file of Scene class
  2. Create an instance of AmfSaveOptions
  3. Set GLTF specific properties for advanced conversion
  4. Call the Scene.save method
  5. Pass the output path with GLTF file extension & object of GltfSaveOptions
  6. Check resultant GLTF file at specified path

System Requirements

Before running the Python conversion code, make sure that you have the following prerequisites.

  • Microsoft Windows or Linux based OS.
  • Python 3.5 or later.
  • Aspose.3D for Python referenced in your project.
  • A 3D File Processing Library to manipulate 3D files without any modeling and rendering software. The 3D API supports Discreet3DS, WavefrontOBJ, FBX (ASCII, Binary), STL (ASCII, Binary), Universal3D, Collada, glTF, GLB, PLY, DirectX, Google Draco file formats and more. Developers can create, read, convert, modify and control the substance of 3D document formats easily.

    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.

    gltf What is gltf File Format?

    glTF (GL Transmission Format) is a 3D file format that stores 3D model information in JSON format. The use of JSON minimizes both the size of 3D assets and the runtime processing needed to unpack and use those assets. It was adopted for the efficient transmission and loading of 3D scenes and models by applications. glTF was developed by the Khronos Group 3D Formats Working Group and is also described as JPEG of 3D by its creators. The format defines an extensible, common publishing format for 3D content tools and services that streamlines authoring workflows and enables interoperable use of content across the industry. The intention behind the creation of glTF file format was to define an extensible, common publishing format for 3D content tools and services that should streamline authoring workflows and enable interoperable use of content across the industry. It minimizes runtime processing by applications using WebGL and other APIs.
