Convert OBJ to PDF via C#

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

How to Convert OBJ to PDF Using C#

In order to convert OBJ to PDF, 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 OBJ to PDF via C#

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

Load OBJ file via the constructor of Scene class
Create an instance of PdfSaveOptions
Set PDF specific properties for advanced conversion
Call the Scene.Save method
Pass the output path with PDF file extension & object of PdfSaveOptions
Check resultant PDF 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.

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.

pdf What is pdf File Format?

Portable Document Format (PDF) is a type of document created by Adobe back in 1990s. The purpose of this file format was to introduce a standard for representation of documents and other reference material in a format that is independent of application software, hardware as well as Operating System. PDF files can be opened in Adobe Acrobat Reader/Writer as well in most modern browsers like Chrome, Safari, Firefox via extensions/plug-ins. Most of the commercially available software suites also offer conversion of their documents to PDF file format without the requirement of any additional software component. Thus, PDF file format has full capability to contain information like text, images, hyperlinks, form-fields, rich media, digital signatures, attachments, metadata, Geospatial features and 3D objects in it that can become as part of source document.
