Streaming 3D holograms into Unity

Let's start with something simple.

1. Either open the sample scene under Assets/echoAR/Examples/sample

or create a new empty game object and attach the script echoAR/echoAR.cs to it.

2. In the Inspector View for the echoAR game object or the empty game object that you created, update the API Key field with your API key.

3. Add a 3D model through the console. Here's how:

4. Go back to Unity and hit the Play button. The SDK will stream the 3D model into Unity.

Great work! 🎉

Real-time updates and animations

You can go back to the console to add more 3D models, delete 3D models, add metadata, or change existing metadata associated with your entry and instantly see the changes in Unity even while the Unity project is running.

For example, lets add metadata with the key direction and the value right. Here's how:

This will make the 3D model rotated to the right.

The following keys are words the system uses as pre-defined metadata keys to control real-time transformations:
