How to import a 3D model into WPF using Helix Toolkit?

Question

I am trying to import a 3D model using Helix Toolkit.i, I can’t figure out how to do this. Is there an online guide for importing a 3D model using this toolkit, or is there another simpler way to import a 3D model other than Helix.

Hi

This is my code:

using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Windows; using System.Windows.Controls; using System.Windows.Data; using System.Windows.Documents; using System.Windows.Input; using System.Windows.Media; using System.Windows.Media.Imaging; using System.Windows.Navigation; using System.Windows.Shapes; using System; using System.IO; using System.Windows.Media.Media3D; namespace WpfApplication1 { /// <summary> /// Interaction logic for MainWindow.xaml /// </summary> public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); } Model3DGroup group = HelixToolkit.Wpf.ModelImporter.Load(@"C:\Jack_Shephard\Jack_Shephard.obj"); public static Model3DGroup Load(string path) { if (path == null) { return null; } Model3DGroup model = null; string ext = System.IO.Path.GetExtension(path).ToLower(); switch (ext) { case ".3ds": { var r = new HelixToolkit.Wpf.StudioReader(); model = r.Read(path); break; } case ".lwo": { var r = new HelixToolkit.Wpf.LwoReader(); model = r.Read(path); break; } case ".obj": { var r = new HelixToolkit.Wpf.ObjReader(); model = r.Read(path); break; } case ".objz": { var r = new HelixToolkit.Wpf.ObjReader(); model = r.ReadZ(path); break; } case ".stl": { var r = new HelixToolkit.Wpf.StLReader(); model = r.Read(path); break; } case ".off": { var r = new HelixToolkit.Wpf.OffReader(); model = r.Read(path); break; } default: throw new InvalidOperationException("File format not supported."); } return model; } } } 

Answer 1

Their documentation is still under construction, but looking at the source code, it seems like you want ModelImporter . It returns Model3dGroup , and its use will look as follows.

  Model3DGroup group = HelixToolkit.Wpf.ModelImporter.Load(@"Your path here"); 

Answer 2

Only you need to put this:

 <HelixToolkit:FileModelVisual3D x:Name="model1" Source="C:\$path\test_obj.obj"/>
