Leap Motion座標系重新瞄準

Question

我試圖將Leap Motion默認座標系從Leap Motion控制器更改爲骨架中的骨骼。

這段腳本有了飛躍，我希望有人可以幫我解決這個問題。

由於我是新手，在使用我的語法時遇到了一些問題。

謝謝

我不知道我是否可以完全理解你的問題。但是，如果你想將數據轉換成骨架，那麼請看這個代碼。

// using Mesh, a custom class of mine 
public List<GeometryModel3D> drawLeftHand(Hand hand) { 
     List<GeometryModel3D> list = new List<GeometryModel3D>(); 
     for (int i = 0; i < hand.Fingers.Count; i++) 
     { 
      // material = materials[i]; 
      Finger finger = hand.Fingers[i]; 
      List<Bone> allBones = new List<Bone>(); 

      Bone _m = finger.Bone(Leap.Bone.BoneType.TYPE_METACARPAL); 
      Bone _pp = finger.Bone(Leap.Bone.BoneType.TYPE_PROXIMAL); 
      Bone _ip = finger.Bone(Leap.Bone.BoneType.TYPE_INTERMEDIATE); 
      Bone _dp = finger.Bone(Leap.Bone.BoneType.TYPE_DISTAL); 
      allBones.Add(_m); 
      allBones.Add(_pp); 
      allBones.Add(_ip); 
      allBones.Add(_dp); 

      for (int j = 0; j < allBones.Count; j++) 
      { 
       material = materials[j]; 
       if (allBones[j].IsValid) 
       { 
        Vector before = allBones[j].PrevJoint; 

        GeometryModel3D sphere = new GeometryModel3D(mesh.createSphere(new Point3D(before.x, before.y, before.z)), material); 
        list.Add(sphere); 
        Vector after = allBones[j].NextJoint; 
        GeometryModel3D cylinder = new GeometryModel3D(mesh.createCylinder(new Point3D(before.x, before.y, before.z), new Point3D(after.x, after.y, after.z)), material); 
          list.Add(cylinder); 

          if (j == allBones.Count - 1) 
          { 
           Vector last = allBones[j].NextJoint; 
           GeometryModel3D _sphere = new GeometryModel3D(mesh.createSphere(new Point3D(last.x, last.y, last.z)), material); 
           list.Add(_sphere); 
          }  
       } 
      } 
     } 
     return list; 
    } 

的位置點是爲了得到每對接頭，並將它們與骨連接到有類似的O-O-O-O

我不能分享我的整個項目還沒有。我很快就會把它GitHub。但如果你有任何問題隨時問。
