Import 3D Scenes and Contents from a PDF in C#

The Scene class of the Aspose.3D API represents a 3D scene. Developers can extract 3D scenes and contents from a PDF file.

Open Scene from a Password Protected PDF

The Open method of the Scene class allows to load the 3D scene from an input PDF file. Developers may also apply password for the protected PDFs using PdfLoadOptions class as shown in this C# code example:

// For complete examples and data files, please go to https://github.com/aspose-3d/Aspose.3D-for-.NET
// Create a new scene
Scene scene = new Scene();
// Use loading options and apply password
PdfLoadOptions opt = new PdfLoadOptions() { Password = Encoding.UTF8.GetBytes("password") };
// Open scene
scene.Open("House_Design.pdf", opt);

Extract All Raw 3D Contents from a PDF

The Extract method of the PdfFormat class allows to extract 3D contents from a PDF file. Developers may iterate through the contents, and save them into the separate files as shown in this C# code example:

// For complete examples and data files, please go to https://github.com/aspose-3d/Aspose.3D-for-.NET
// The path to the documents directory.
byte[] password = null;
// Extract 3D contents
List<byte[]> contents = FileFormat.PDF.Extract("House_Design.pdf", password);
int i = 1;
// Iterate through the contents and in separate 3D files
foreach (byte[] content in contents)
{
    string fileName = "3d-" + (i++);
    File.WriteAllBytes(fileName, content);
}

Extract All 3D Scenes and Save them into Supported 3D Formats

The ExtractScene method of the PdfFormat class allows to extract 3D scenes from a PDF file. Developers may iterate through the scenes, and save them in the supported 3D file formats as shown in this C# code example:

// For complete examples and data files, please go to https://github.com/aspose-3d/Aspose.3D-for-.NET

            byte[] password = null;
            List<Scene> scenes = FileFormat.PDF.ExtractScene("House_Design.pdf", password);
            int i = 1;
            // Iterate through the scenes and save in 3D files
            foreach (Scene scene in scenes)
            {
                string fileName = "3d-" + (i++) + ".fbx";
                scene.Save(RunExamples.GetOutputFilePath(fileName), FileFormat.FBX7400ASCII);
            }

All the supported 3D file formats are listed in the Product Overview page.
