This contains the Project Tango C API examples.

These examples use the Gradle build system and were developed using Android Studio 2.1.

Basic Examples

The cpp_basic_examples project includes basic examples showing how to compile and run an application using C/C++:

• hello_area_description - Use the Area Description API to create and manage Area Description Files.
• hello_depth_perception - Use the depth sensor.
• hello_motion_tracking - Use the Motion Tracking API to track the position of the Tango device in 3D space.
• hello_video - Render the RGB camera image using OpenGL.

Use Case Examples

Other examples in this repository show how to build an application for different use cases of Tango technology:

• cpp_augmented_reality_example - Achieve an augmented reality effect by rendering 3D objects overlaid on the camera image such that they appear to stay affixed in space.
• cpp_marker_detection_example - Build an augmented reality appliction to detect Alvar markers in real world, and to render 3D objects over the markers.
• cpp_mesh_builder_example - Use the depth sensor to build a mesh of the surrounding space.
• cpp_motion_tracking_example - Use Tango motion tracking to navigate in a virtual 3D world.
• cpp_plane_fitting_example - Build an AR application to detect planes in the real world to place objects in them.
• cpp_point_cloud_example - Acquire and render a cloud of 3D points using the depth sensor.
• cpp_point_to_point_example - Build a simple point-to-point measurement application using augmented reality and the depth sensor.
• cpp_rgb_depth_sync_example - Synchronize the depth sensor 3D information with the color camera information.
• cpp_video_stabilization_experiment - Stabilize the video by smoothing the pose and correcting for gravity.

The cpp_example_util project contains some common utility code that is used for many samples.

Contribution

Want to contribute? Great! First, read this page (including the small print at the end).

Before you contribute

Before we can use your code, you must sign the Google Individual Contributor License Agreement (CLA), which you can do online. The CLA is necessary mainly because you own the copyright to your changes, even after your contribution becomes part of our codebase, so we need your permission to use and distribute your code. We also need to be sure of various other things—for instance, that you'll tell us if you know that your code infringes on other people's patents. You don't have to sign the CLA until after you've submitted your code for review and a member has approved it, but you must do it before we can put your code into our codebase. Before you start working on a larger contribution, you should get in touch with us first through the issue tracker with your idea so that we can help out and possibly guide you. Coordinating up front makes it much easier to avoid frustration later on.

Code reviews

All submissions, including submissions by project members, require review. We use Github pull requests for this purpose.

Contributions made by corporations are covered by a different agreement than the one above: the Software Grant and Corporate Contributor License Agreement.
