示例1: onFrame
void Quickstart::onFrame(const Leap::Controller &controller) {
// returns the most recent frame. older frames can be accessed by passing in
// a "history" parameter to retrieve an older frame, up to about 60
// (exact number subject to change)
const Leap::Frame frame = controller.frame();
// do nothing unless hands are detected
if (frame.hands().empty())
return;
// first detected hand
const Leap::Hand firstHand = frame.hands()[0];
// first pointable object (finger or tool)
const Leap::PointableList pointables = firstHand.pointables();
if (pointables.empty()) return;
const Leap::Pointable firstPointable = pointables[0];
// print velocity on the X axis
cout << "Pointable X velocity: " << firstPointable.tipVelocity()[0] << endl;
const Leap::FingerList fingers = firstHand.fingers();
if (fingers.empty()) return;
for (int i = 0; i < fingers.count(); i++) {
const Leap::Finger finger = fingers[i];
std::cout << "Detected finger " << i << " at position (" <<
finger.tipPosition().x << ", " <<
finger.tipPosition().y << ", " <<
finger.tipPosition().z << ")" << std::endl;
