Working with Watermark

Using the Aspose.3D for .NET API, developers can easily add blind watermarks to 3D files while saving in any supported output file format.

Create a 3D Scene

First you need to create a 3d scene from a 3d file.The following code snippet shows how to use this functionality:

// For complete examples and data files, please go to https://github.com/aspose-3d/Aspose.3D-for-.NET
string file = "template.3ds";
Scene scene = Scene.FromFile(file);

Encode Watermark

Aspose.3D for .NET adds watermark text information and watermark password to 3d files through the EncodeWatermark method. The following code snippet shows how to use this functionality:

// For complete examples and data files, please go to https://github.com/aspose-3d/Aspose.3D-for-.NET
var numMeshes = 0;
scene.RootNode.Accept((Node node) =>
{
    var mesh = node.GetEntity<Mesh>();
    if (mesh != null)
    {
        numMeshes++;
        mesh = Watermark.EncodeWatermark(mesh, "HelloWorld", "1234");
        if (mesh != null)
        {
            node.Entity = mesh;
        }
    }
    return true;
});

Save Document

You can save to any 3d file format you want.The following code snippet shows how to use this functionality:

// For complete examples and data files, please go to https://github.com/aspose-3d/Aspose.3D-for-.NET
string output = "output.fbx";
scene.Save(output, FileFormat.FBX7400ASCII);
