wpf动态加载obj格式的3D模型

前几天一个网友发现一个工具中有一个3D加载的代码，于是抽了出来加以修改。我也有幸拿到一份。现在拿出来和大家分享。

以下是我的一简单的加载代码：obj文件所在的路径请自行修改

 1:  PerspectiveCamera myPCamera;

 2:  

 3:          public MainWindow()

 4:          {

 5:              InitializeComponent();

 6:              WavefrontObjLoader wfl = new WavefrontObjLoader();

 7:              slider1.ValueChanged += new RoutedPropertyChangedEventHandler<double>(slider1_ValueChanged);

 8:              slider2.ValueChanged += new RoutedPropertyChangedEventHandler<double>(slider1_ValueChanged);

 9:              slider3.ValueChanged +=new RoutedPropertyChangedEventHandler<double>(slider1_ValueChanged);

10:  

11:             myPCamera = new PerspectiveCamera();

12:  

13:             // Specify where in the 3D scene the camera is.

14:             myPCamera.Position = new Point3D(0, 0, 200);

15:  

16:             // Specify the direction that the camera is pointing.

17:             myPCamera.LookDirection = new Vector3D(0, 0, -1);

18:  

19:             // Define camera's horizontal field of view in degrees.

20:             myPCamera.FieldOfView = 1000;

21:  

22:             // Asign the camera to the viewport

23:             vp.Camera = myPCamera;

24:  

25:             Model3DGroup myModel3DGroup = new Model3DGroup();

26:  

27:             DirectionalLight myDirectionalLight = new DirectionalLight();

28:             myDirectionalLight.Color = Colors.White;

29:             myDirectionalLight.Direction = new Vector3D(-0.61, -0.5, -0.61);

30:  

31:             myModel3DGroup.Children.Add(myDirectionalLight);

32:             var m = wfl.LoadObjFile(@"d:\3d\1.obj");

33:              m.Content =myModel3DGroup;

34:             vp.Children.Add(m);

35:          }

36:  

37:          void slider1_ValueChanged(object sender, RoutedPropertyChangedEventArgs<double> e)

38:          {

39:              myPCamera.Position = new Point3D(slider2.Value , slider1.Value, slider3.Value);

40:          }

41:  

此类有一部份的obj文件加载不到，可能是因为支持不了太新的3Dmax工具生成的文件.
