Detailed Description

The CircleGesture classes represents a circular finger movement.

Deprecated:: 3.0

Constructor & Destructor Documentation

CircleGesture ( )

Constructs a new CircleGesture object.

An uninitialized CircleGesture object is considered invalid. Get valid instances of the CircleGesture class from a Frame object.

Deprecated:: 3.0

CircleGesture ( Gesture rhs )

Constructs a CircleGesture object from an instance of the Gesture class.

if(gesture.type() == Gesture.Type.TYPE_CIRCLE) {
    CircleGesture circleGesture = new CircleGesture(gesture);
}

Parameters

rhs	The Gesture instance to specialize. This Gesture instance must be a CircleGesture object.

Member Function Documentation

Vector center ( )

The center point of the circle within the Leap Motion frame of reference.

Vector centerPoint = circle.center();

Returns: Vector The center of the circle in mm from the Leap Motion origin.

Deprecated:: 3.0

static Gesture.Type classType ( )

static

The circle gesture type.

if(gesture.type() == CircleGesture.classType()) {
    CircleGesture circleGesture = new CircleGesture(gesture);
}

Returns: Type The type value designating a circle gesture.

Deprecated:: 3.0

Vector normal ( )

Returns the normal vector for the circle being traced.

String clockwiseness;
if (circle.pointable().direction().angleTo(circle.normal()) <= Math.PI/2) {
        clockwiseness = "clockwise";
}
else
{
    clockwiseness = "counterclockwise";
}
