3D 큐브를 그리려는데 작동하지 않습니다.

편집 내부 코드 : 고정
안녕하세요 여러분, 내가 가지고 내 창에 다음과 같은 이벤트 핸들러 :

private void buttonView_Click(object sender, RoutedEventArgs e) 
{ 
    //Camera 
    PerspectiveCamera camera = new PerspectiveCamera(); 
    camera.LookDirection = new Vector3D(5, -2, -3); 
    camera.Position = new Point3D(-5, 2, 3); 
    camera.UpDirection = new Vector3D(0, 1, 0); 
    camera.NearPlaneDistance = 1; 
    camera.FarPlaneDistance = 10; 
    //Lighting 
    DirectionalLight light = new DirectionalLight(Colors.White, new Vector3D(-3, -4, -5)); 
    //Cube 
    Cube cube = new Cube(); 
    GeometryModel3D cubeModel = new GeometryModel3D(); 
    cubeModel.Geometry = cube.Mesh; 
    cubeModel.Material = new DiffuseMaterial(Brushes.Red); 
    //ModelGroup 
    Model3DGroup modelGroup = new Model3DGroup(); 
    modelGroup.Children.Add(light); 
    modelGroup.Children.Add(cubeModel); 
    //Model 
    ModelVisual3D model = new ModelVisual3D(); 
    model.Content = modelGroup; 
    //Viewport 
    Viewport3D view = new Viewport3D(); 
    view.Camera = camera; 
    view.Children.Add(model); 
    //Show it all 
    Frame f = new Frame(); 
    f.Content = view; 
    grid1.Children.Add(f); 
} 

이 내 큐브 클래스입니다 : 그러나

public class Cube : Primitive 
{ 
    Point3D[] positions = new Point3D[] { 
     new Point3D(0, 1, 1), 
     new Point3D(0, 0, 1), 
     new Point3D(1, 1, 1),

     new Point3D(1, 1, 0), 
     new Point3D(1, 0, 0), 
     new Point3D(0, 1, 0), 
     new Point3D(0, 0, 0) 
     }; 
    int[] vertices = new int[] {

    public Cube() 
    { 
     this.Mesh.Positions = new Point3DCollection(positions); 
     this.Mesh.TriangleIndices = new Int32Collection(vertices); 
    } 
} 

public abstract class Primitive 
{ 
    public Primitive() 
    { 
     this.Mesh = new MeshGeometry3D(); 
    } 
    public MeshGeometry3D Mesh { get; protected set; } 
} 

, 내가 클릭하면 버튼, 아무것도 표시되지 않습니다. 내 이벤트 처리기에 오류가 있습니까?

Answer 1

나는 바보입니다. 죄송합니다. 문제는 설정하지 않았다는 것입니다.

camera.FarPlaneDistance 단지 camera.NearPlaneDistance (두 번)입니다.
불편을 끼쳐 드려 죄송합니다..
