Last Updated: July 2, 2024

Import an external 3D asset into a Sony Spatial Reality Display (SRD) project in Unity from the echo3D cloud.

  • Built with Unity 2021.3.25f1 (Note: The echo3D Unity SDK requires 2020.3.25+).
  • Register for a FREE echo3D account.
  • Clone this repo to view the sample project. The echo3D SDK has already been installed.
  • Install the SRD Unity Plugin by following the instructions here.
  • Add the 'Skyscraper' model to the echo3D console.
  • Disable the Collection's API token / security key / secret key.
  • Open the sample project in Unity
  • Open the 'SRDisplaySimpleSample' scene under Assets
  • Select the 'echo3DHologram' object in the Hierarchy.
  • Note that 'Echo 3D Hologram (Script)' in the Inspector is disabled and that 'Editor Preview' checkbox is checked. It will be enabled on runtime once the API key is set in the Input Field and the 'Start' button is clicked.
  • In the echo3D console, double-click on the 'Skyscraper' card and go to 'Metadata'.
  • Add 'scale' with value 20.
  • Adjust the SRDisplay by setting the Uniform scale of the SRDisplay Manager to 100 using the SRD View Space Scale slider. Adjust UI elements as needed. If you intend to support both wallmount mode and standard mode, please toggle Is Wallmount Mode on the SRDisplay settings in the Inspector.
  • Creating a mouse pointer as regular 2D mouse pointers won’t work on the SRD as the SRD is in 3D Space. Please use the Pointer script provided in the SRD Plugin to create a 3D mouse pointer.
  • Assign the mouse pointer event in the SRD Graphic Raycaster script according to the image below. The SRD Graphic Raycaster script should replace the Graphic Raycaster script on the Canvas.
  • Adjust the Event System to help the SRD cameras detect controller input. In the Event System game object, replace the Standalone Input Module with the SRD Standalone Input Module from the SRD plugin. SRD Standalone Input Module extends Standalone Input Module.
  • Make sure the SRD canvas Render Mode is set to World Space.
  • Adjust UI view space to SRD to make sure 2D UI elements show up on the SRD. Adjust all UI elements to the SRD’s view space. Create a parent for the Canvas. Attach the SRD View Space Scale Follower to said parent.
  • Connect your Sony SRD.
  • In the top menu under SpatialRealityDisplay, enable SRDisplay GameView (Full Screen).
  • Click 'Play' in Unity.
  • Set your API key on the Input Field.
  • Click 'Start'.
  • Watch the building appear.
  • That's it! 🎉

No SRD?

  • Select the 'echo3DHologram' object in the Hierarchy.
  • Enable the Echo3DHologram gameobject.
  • Right-click the 'Echo 3D Hologram (Script)' in the Inspector and click 'Edit Script'.
  • Comment out line 78 in the Echo3DHologram.cs script to avoid loading the API key through the Input Field.
  • (Optional) Add a specific 'Asset ID' (can be copied from the console) to the Entries in the Inspector.
  • In the Unity taskbar, click Echo3D > Load Editor Holograms to watch the building appear.
