Unigine.VRMarkerObject Class

Object markers are used to track static or dynamic objects in the user environment. You can use the object markers in both XR and VR applications. Each marker has a unique ID, and you shouldn't use the same marker more than once in any given environment. For added precision, an application can use multiple markers to track a single object. You can, for example, track a monitor by placing a marker in each corner.

Properties:

Name	Description
int ID	The unique ID of the marker object.
mat4 Transform	The marker pose transformation.
mat4 WorldTransform	The marker pose transformation in global space.
vec3 Size	The size of the marker.
vec3 Velocity	The linear velocity.
vec3 AngularVelocity	The angular velocity.
vec3 Acceleration	The acceleration.
long RawTimestamp	The timestamp of the pose.
double Confidence	The tracker confidence.
int PoseFlags	The bit field value describing pose.
bool Dynamic	The value indicating if the marker is tracked as dynamic (the marker pose is predicted).
float Lifetime	The lifetime of the marker.

Methods:

Name	Description View: Sort by:
RenderVisualizer	Renders visualizer for the marker object.

Variables:

Name	Description
MARKER_POSE_FLAGS_TRACING_OK = 0x1	Pose is being currently tracked.
MARKER_POSE_FLAGS_TRACING_LOST = 0x2	Pose has been tracked but currently is not detected by the tracking subsystem.
MARKER_POSE_FLAGS_TRACING_DISCONNECTED = 0x4	Tracking subsystem is not connected and poses cannot be acquired.
MARKER_POSE_FLAGS_HAS_POSITION = 0x8	Pose has position information.
MARKER_POSE_FLAGS_HAS_ROTATION = 0x10	Pose has rotation information.
MARKER_POSE_FLAGS_HAS_VELOCITY = 0x20	Pose has velocity information.
MARKER_POSE_FLAGS_HAS_ANGULAR_VELOCITY = 0x40	Pose has angular velocity information.
MARKER_POSE_FLAGS_HAS_ACCELERATION = 0x80	Pose has acceleration information.
MARKER_POSE_FLAGS_HAS_CONFIDENCE = 0x100	Pose has confidence information.
