Develop With Depth

The world's most advanced spatial computing platform.

Structure SDK Features

Never developed with a 3D sensor before? Structure SDK includes high-level APIs that get you started quickly. Need precise 6-DoF positional tracking? Volumetric reconstruction? Real world occlusion? Our APIs have you covered. Prefer to develop at a low level? You'll have direct access to the same raw data and low-level controls on Structure Sensor that we do.

Effortlessly Create iOS Apps with 3D Sensing

The Structure SDK provides developers with a stable, easy-to-use, flexible and constantly-improving framework for creating iOS applications in Xcode which leverage advanced computer vision capabilities and techniques.

Just drop Structure.framework into your Xcode project, initialize the Structure Sensor in your code... and you're ready to develop with depth. It's really that easy.

Download Structure SDK >

Apps created with Structure SDK can be launched on the App Store. The Structure SDK contains source code for sample apps with 3D scanning, indoor mapping and more to get you started.

Initializing Structure Sensor in five lines of code:

[[STSensorController sharedController] initializeSensorConnection];

[STSensorController sharedController].delegate = self;

[[STSensorController sharedController] startStreamingWithOptions:
  @{ kSTStreamConfigKey    : @(STStreamConfigDepth640x480),
     kSTFrameSyncConfigKey : @(STFrameSyncDepthAndRgb) } error:nil];

Integrate with Popular 3D Engines

Structure Sensor and Structure SDK can be easily combined with 3D rendering and video game engines like Unity and SceneKit using the plugins and sample code provided in Structure SDK.


Structure SDK comes complete with plugins for Unity. You can create augmented reality (AR) apps complete with real-world occlusion. You can also use the six-degree-of-freedom (6-DoF) Unbounded Positional Tracking to control your 3D player’s point of view in a game or other virtual world.


Structure SDK can also be used out of the box with sample code to integrate with SceneKit, a simple but powerful 3D engine provided with Xcode on iOS 8 and above.
