如何旋轉相機 - 相機旋轉

Question

我想知道是否有一個變量或方式我可以用來旋轉我的遊戲中的相機。我可以沿xyz軸移動它，但我無法弄清楚如何旋轉它！ ：o

下面是變量：

Model spaceShip; 
    float aspectRatio; 
    Vector3 modelPosition = Vector3.Zero; 
    float modelRotation = 0f; 

    Vector3 cameraPosition = new Vector3(0f, 50f, 5000f); 

下面是它的平局（模型（飛船））：

 Matrix[] transforms = new Matrix[spaceShip.Bones.Count]; 
     spaceShip.CopyAbsoluteBoneTransformsTo(transforms); 

     foreach (ModelMesh mesh in spaceShip.Meshes) 
     { 
      foreach (BasicEffect effect in mesh.Effects) 
      { 
       effect.EnableDefaultLighting(); 
       effect.World = transforms[mesh.ParentBone.Index] * Matrix.CreateRotationY(this.modelRotation) * Matrix.CreateTranslation(this.modelPosition); 
       effect.View = Matrix.CreateLookAt(this.cameraPosition, Vector3.Zero, Vector3.Up); 
       effect.Projection = Matrix.CreatePerspectiveFieldOfView(MathHelper.ToRadians(45f), aspectRatio, 1f,200000f); 
      } 
      mesh.Draw(); 
     } 

和這個長寬比被加載在：

aspectRatio = graphics.GraphicsDevice.Viewport.AspectRatio;

你可以試着旋轉場景的根容器（這不應該包含攝像頭，攝像頭，你應該有根之外的另一個容器）周圍的攝像機觀察方向矢量
