Question

我正在尝试使用Helix Toolkit导入3D模型。我无法弄清楚如何做到这一点。是否有任何关于使用此工具包导入3D模型的在线指南，或者是否有另一种更简单的方法来导入除Helix之外的3D模型。

这是我的代码：

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

他们的文档仍在构建中，但在查看源代码时，您似乎需要ModelImporter方法。它返回Model3dGroup，其用法如下所示。

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

Answer 2

只有你需要这个：

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