Convert GLTF to U3D via C#

Render GLTF as U3D without any 3D modeling and rendering software.

How to Convert GLTF to U3D Using C#

In order to convert GLTF to U3D, we’ll use

Aspose.3D for .NET

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

NuGet

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

Package Manager Console Command
PM> Install-Package Aspose.3D

Steps to Convert GLTF to U3D via C#

.NET programmers can easily load & convert GLTF files to U3D in just a few lines of code.

Load GLTF file via the constructor of Scene class
Create an instance of AmfSaveOptions
Set U3D specific properties for advanced conversion
Call the Scene.Save method
Pass the output path with U3D file extension & object of U3dSaveOptions
Check resultant U3D file at specified path

System Requirements

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

Microsoft Windows or a compatible OS with .NET Framework, .NET Core, Mono.
Development environment like Microsoft Visual Studio.
Aspose.3D for .NET DLL 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.

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.

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.
