LeapMotion Class

Перечисления (Enums)

POLICY#

Имя	Описание
DEFAULT = 0	Default policy flag. Enables default policy settings.
BACKGROUND_FRAMES = 1 << 0	Background frames policy flag. Determines whether an application receives frames of tracking data while in the background. Notice By default, the Leap Motion software only sends tracking data to the foreground application. Only applications that need this ability should request the background frames policy. The "Allow Background Apps" checkbox must be enabled in the Leap Motion Control Panel or this policy will be denied.
IMAGES = 1 << 1	Images policy flag. Enables your application to receive images from the device cameras. Notice The "Allow Images" checkbox must be enabled in the Leap Motion Control Panel or this policy will be denied.
OPTIMIZE_HMD = 1 << 2	HMD optimization policy flag. Enables tracking optimization for head-mounted tracking mode. Notice This policy improves tracking in situations where the Leap Motion hardware is attached to a head-mounted display. This policy is not granted for devices that cannot be mounted to an HMD, such as Leap Motion controllers embedded in a laptop or keyboard.
ALLOW_PAUSE_RESUME = 1 << 3	Pause resume policy flag. Determines if the application is allowed to pause and unpause the Leap Motion service.
RAW_IMAGES = 1 << 6	Images policy flag. Enables your application to receive raw images from the device cameras.

Members

---

bool HasFocus ( ) #

Returns a value indicating if the application is the focused (foreground) application.

Return value

true if the application is the focused (foreground) application; otherwise, false.

void SetPolicy ( int policy ) #

Requests setting the specified policy. A request to change a policy is subject to user approval and a policy can be changed by the user at any time (using the Leap Motion settings dialog).

Arguments

• int policy - Policy. One of the POLICY values.

bool IsPolicySet ( int policy ) #

Returns a value indicating if the specified policy is set. To set a policy use the SetPolicy() method.

Arguments

• int policy - Policy type. One of the POLICY values.

Return value

true if the specified policy is set; otherwise, false.

void ClearPolicy ( int policy ) #

Requests clearing the specified policy. A request to change a policy is subject to user approval and a policy can be changed by the user at any time (using the Leap Motion settings dialog).

Arguments

• int policy - Policy. One of the POLICY values.

float GetDistanceToBoundary ( vec3 position ) #

Returns the distance from the specified point to the nearest edge of the Leap Motion controller's view volume. The view volume is an axis-aligned, inverted pyramid centered on the device origin and extending upward to the range limit. The walls of the pyramid are described by the horizontalViewAngle and verticalViewAngle and the roof by the range.

Arguments

• vec3 position - Point to measure the distance from.

Return value

Distance from the specified point to the nearest edge of the Leap Motion controller’s view volume, in meters.

int GetNumImages ( ) #

Returns the number of images stored in the list of the most recent images from the infrared stereo cameras of the device. Images are in the Image::FORMAT_R8.

Return value

Number of images stored in the array.

Ptr<Image> & GetImage ( int num ) #

Returns the selected image from the list of the most recent images from the infrared stereo cameras of the device. Images are in the Image::FORMAT_R8.

Arguments

• int num - Index number of the image in the array.

Return value

Selected image from the cameras.
