Unity client for Open Spatial Computing Platform

This is a Unity client for Open AR Cloud's Open Spatial Computing Platform.

The app was originally created in 2021 by Augmented City based on their AC Viewer app. It was extended by 3DInteractive and Nokia in 2022 in a project funded by NGI Atlantic. In 2025, Unity upgrade and refactoring was done by Nokia in a project funded by NGI Search.

Authentication

To test the login you need to use the Scene Login and add requried url:s and secrets. On object "@Oauth2" in the scene heirarcy. I tested this using Auth0 but it should support anything that uses OAuth2.0. The authentication uses PKCE flow and deep linking

Required information

• Client ID
• Client Secret
• Authorization Endpoint
• Token Endpoint
• UserInfo Endpoint
• Redirect URL

Deep Link in Unity

• https://docs.unity3d.com/2019.3/Documentation/Manual/enabling-deep-linking.html

Enable Deep Link Android

For deep link to work on Android you need to follow your login services. The AndroidManifest.xml also need to add intent and the deep link url
