Leap Motion 探究 【第二篇】

       昨晚搗鼓完Leap的數據輸出，一看時間還早，寫完前一篇博文，後手就開始寫這個東西。團隊是做飛行模擬設備的，我就直接拿微軟模擬飛行來做個例子（模擬器接口部分不放開，主要看怎麼整合Leap應用到外圍）。測試視頻鏈接：http://player.youku.com/player.php/sid/XMTU1MTkwNzU4MA==/v.swf

public partial class Form1 : Form
    {
        FListener MyListener = new FListener();
        Controller MyController = new Controller();

        short PitchFS;//模擬器中的Pitch值
        short RollFS;//模擬器中的Roll值
        short YawFS;//模擬器中的Yaw值
        public Form1()
        {
            InitializeComponent();
        }

        private void ConnectToLeap_Click(object sender, EventArgs e)
        {
            MyController.AddListener(MyListener);
            try
            {
                //FSX 通道預位
                DisConnectToLeap.Enabled = true;
                ConnectToLeap.Enabled = false;
                timer1.Enabled = true;
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
        }

        private void DisConnectToLeap_Click(object sender, EventArgs e)
        {
            MyController.RemoveListener(MyListener);
            MyController.Dispose();
            DisConnectToLeap.Enabled =false;
            ConnectToLeap.Enabled = true;
            timer1.Enabled = false;
            //FSX 通道關閉
        }

        private void timer1_Tick(object sender, EventArgs e)
        {
            PitchFS = (short)(MyListener.PitchRaw / 90 * 16383);
            RollFS = (short)(MyListener.RollRaw / 90 * 16383);
            YawFS = (short)(MyListener.YawRaw / 90 * 16383);
            textPitch.Text = ((short)(MyListener.PitchRaw / 90 * 16383)).ToString();
            textRoll.Text = ((short)(MyListener.RollRaw / 90 * 16383)).ToString();
            textYaw.Text = ((short)(MyListener.YawRaw / 90 * 16383)).ToString();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.FixedSingle;
        }
    }

以上是Form類中的代碼，與Leap提供的example幾乎一致。後面看一下Listener的代碼，我只取得了我需要的數據，剩下不需要的統統不要。

public class FListener : Listener
    {
        public float PitchRaw, RollRaw, YawRaw;
        public override void OnInit(Controller arg0)
        {
            Console.WriteLine("Initialized.");
        }

        public override void OnConnect(Controller arg0)
        {
            Console.WriteLine("Connected.");
            arg0.EnableGesture(Gesture.GestureType.TYPE_CIRCLE);
            arg0.EnableGesture(Gesture.GestureType.TYPE_KEY_TAP);
            arg0.EnableGesture(Gesture.GestureType.TYPE_SCREEN_TAP);
            arg0.EnableGesture(Gesture.GestureType.TYPE_SWIPE);
        }

        public override void OnDisconnect(Controller arg0)
        {
            Console.WriteLine("Disconnected.");
        }

        public override void OnExit(Controller arg0)
        {
            Console.WriteLine("Exited");
        }

        public override void OnFrame(Controller arg0)
        {
            Frame frame = arg0.Frame();
            foreach (Hand hand in frame.Hands)
            {
                Vector normal = hand.PalmNormal;
                Vector direction = hand.Direction;
                Console.WriteLine("Hand pitch: " + direction.Pitch * 180.0f / (float)Math.PI + "   "
                            + "roll: " + normal.Roll * 180.0f / (float)Math.PI + "   "
                            + "yaw: " + direction.Yaw * 180.0f / (float)Math.PI + "   ");
                PitchRaw = direction.Pitch * 180.0f / (float)Math.PI;
                RollRaw = normal.Roll * 180.0f / (float)Math.PI;
                YawRaw = direction.Yaw * 180.0f / (float)Math.PI;
            }
        }
    }

這篇寫的比較簡單，沒有創新什麼東西，只是將第一篇的東西做了一個“東西”出來，後面將測試幾個手勢。
