This contains the Project Tango Java API examples.

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

Basic Examples

The java_basic_examples project includes basic examples showing how to compile and run an application using different core Tango APIs in Java:

• hello_motion_tracking - Use the Motion Tracking API to track the position of the Tango device in 3D space.
• hello_area_description - Use the Area Description API to create and manage Area Description Files.
• hello_depth_perception - Use the depth sensor.
• hello_video - Show how to 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.

Most of these examples delegate the details of OpenGL rendering to the Rajawali engine, so that the example code can focus on the Tango-specific aspects of the application.

• java_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.
• java_floor_plan_example - Create a floor plan by using the depth sensor to detect and mesure walls in a room.
• java_marker_detection_example - Build an augmented reality appliction to detect AR markers in real world, and to render the boundaries and poses of markers.
• java_model_correspondence_example - Create a mapping between a virtual 3D object and selected points in the real world.
• java_motion_tracking_example - Use Tango motion tracking to navigate in a virtual 3D world.
• java_opengl_augmented_reality_example - Achieve an augmented reality effect without using any third party 3D rendering library.
• java_plane_fitting_example - Build an AR application to detect planes in the real world to place objects in them.
• java_point_cloud_example - Acquire and render a cloud of 3D points using the depth sensor.
• java_point_to_point_example - Build a simple point to point measurement application using augmented reality and the depth sensor.

The java_examples_utils project contains some common utility code that is used for many examples.

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.
