Hello. I’m having hard time to find a cross platform 3D engine that could integrate into an existing native ios (Xcode) / android (Android studio) app. I would like at one point in the app to present a 3D view developed with Urho3D. Thanks for any help.
Hi @jptsetung, and welcome to the forums! 
Although it should be technically possible, could you more specifically describe what you’re looking to accomplish as well as any obstacles you may see ahead or have already encountered?
I have an app which is not a 3D app, it show classic user interface views for iOS and android. At some point in the app, I want to launch a 3D view (full screen), and I wanted to study the possibility to use a 3D engine like Urho3D to do this. All utotirlas I read are based on cmake which build a whole app using the 3D engine, but didn’t see any tutorial about integrating the engine in an existing app.
Maybe you could use Edddy as an example, or @aster2013’s particle editor, which has a quite similar approach.
