Developer Tools
Plugins that receive Motive data.
Camera SDK
Full control, 2D data, sync, and vector tracking — the tools you need to build applications.
NatNet SDK
Integrate OptiTrack data into apps, plugins, or engines for smooth, real-time streaming use.
Batch programmer
Advanced utility to reprogram and configure OptiTrack Active hardware beyond factory setup.
Camera SDK
The Camera SDK is a free development package that enables users to control and capture from OptiTrack cameras in order to create custom tracking and vision applications.
The SDK includes full camera control, access to 2D object data, camera synchronization, and comprehensive vector tracking—a complete assortment of tools to create cost-effective, powerful applications from scratch or integrate with existing software.
Advanced SDK Features
Simple C++ Integration
Offers a modern C++ interface for seamless integration into your application workflows.
Detailed 2D Object Data
Retrieve up to 1000+ objects per frame with position, size, roundness, and lens distortion correction.
Multi-Camera Sync
Capture images multiple cameras simultaneously for fully synchronized frame collection with up to hundreds of cameras.
Full Camera Control
Adjust video modes, exposure, gain, LEDs, and image windowing for complete control of each camera.
Sample Applications
Explore example applications that provide examples for typical camera workflows.
Multiple Operating Systems
Run OptiTrack cameras on Windows, Ubuntu, and Fedora operating systems with simple to use examples.
NatNet SDK
NatNet’s client/server architecture allows client applications to run on the same system as the tracking software (Motive), on separate system(s), or both. The SDK integrates seamlessly with standard APIs (C/C++/.NET), tools (Microsoft Visual Studio) and protocols (UDP/Unicast/Multicast).
SDK Contents
NatNet Library
Native C++ networking library [headers, static library (.lib) and dynamic import library (.lib/.dll)]
NatNet Assembly
Managed .NET assembly (NatNetML.dll) for use in .NET compatible clients.
NatNet Samples
Sample projects and executables designed to be quickly integrated into your own code.
MatNet interface to MATLAB
.NET interface and sample program (MatNet.m) for live streaming markers, rigid bodies, or skeletons. The MatNet sample program works directly with MATLAB core, requiring no additional MATLAB modules.
API Structure
NatNetClient
A class for communicating with a NatNet Server (Motive)
NatNet Data Types
Structures encapsulating data encoded in NatNet packets.
NatNet Assembly
A managed (.NET) class library that can be called by .NET components. The NatNet assembly wraps the underlying native NatNet library, exposing the NatNetClient and NatNet Data Types for use in .NET compatible environments (e.g. VB.NET, C#, MatLab).
Data Types
Marker Set Data
A named collection of identified markers and their positions (X,Y,Z)
Rigid Body Data
A named segment with a unique ID, position, and orientation data, and the collection of identified markers used to define it.
Skeleton Data
A named, hierarchical collection of rigid bodies.
Force Plate Data
Rebroadcast force and moment data.
Device Data
Rebroadcast data from analog devices such as DAQ devices.
