About
The MotionTrackerObject class represents a Cinema 4D motion tracker object. It provides read-only access to properties of the loaded video footage and the created 2D tracks.
MotionTrackerObject objects are an instance of Omotiontracker
.
Access
A MotionTrackerObject object can be accessed like any other object.

Allocation/Deallocation
MotionTrackerObject objects are created with the usual tools:
if (moTrackObj == nullptr)
moTrackObj->
SetName(
"New Motion Tracker"_s);
doc->InsertObject(moTrackObj,
nullptr,
nullptr);
void SetName(const maxon::String &name, Bool setDirty=true)
Definition: c4d_baselist.h:2549
static MotionTrackerObject * Alloc()
Parameters
The standard object parameters of the Motion Tracker object can be accessed with C4DAtom::GetParameter() and C4DAtom::SetParameter(). The parameter IDs are defined in omotiontracker.h
.
Additionally, footage information can be accessed with MotionTrackerObject::GetFootageData() (see below).
Access Data
Internal data of a MotionTrackerObject can be accessed by acquiring specialised data containers that store information on the footage and the 2D tracking data.
See MtFootageData Manual and Mt2dTrackData / Mt2dTrack / MtData Manual.
