Alternatives to libGDX

In my modest opinion, Flutter is the future of mobile development. The framework is as important to mobile as React is to the web. And seeing that React Native does not finish taking off, I am focusing all my efforts on learning Flutter and Dart. The ecosystem is amazing. The community is crazy about Flutter. There are enough resources to learn and enjoy the framework, and the tools developed to work with it are amazing. Android Studio or Visual Studio Code has incredible plugins and Dart is a pretty straight forward and easy-to-learn language, even more, if you came from JavaScript. I admit it. I'm in love with Flutter. When you are not a designer, having a framework focused on design an pretty things is a must. And counting with tools like #flare for animations makes everything easier. It is so amazing that I wish I had a big mobile project right now at work just to use Flutter.

As a Engineering Manager & Director at SmartZip, I had a mix of front-end, back-end, #mobile engineers reporting to me.

Sprints after sprints, I noticed some inefficiencies on the MobileDev side. People working multiple sprints in a row on their Xcode / Objective-C codebase while some others were working on Android Studio. After which, QA & Product ensured both applications were in sync, on a UI/UX standpoint, creating addional work, which also happened to be extremely costly.

Our resources being so limited, my role was to stop this bleeding and keep my team productive and their time, valuable.

After some analysis, discussions, proof of concepts... etc. We decided to move to a single codebase using React Native so our velocity would increase.

After some initial investment, our initial assumptions were confirmed and we indeed started to ship features a lot faster than ever before. Also, our engineers found a way to perform this upgrade incrementally, so the initial platform-specific codebase wouldn't have to entirely be rewritten at once but only gradually and at will.

Feedback around React Native was very positive. And I doubt - for the kind of application we had - no one would want to go back to two or more code bases. Our application was still as Native as it gets. And no feature or device capability was compromised.

We already have an existing 3d interactive application for windows, mac, and iOS devices and have planned to move that app to the web for high availability to different types of users. I have been searching for different options for it. Our existing application is made in Unity so we prefer to work on unity webgl but it also has its drawbacks. Other than that we are also thinking to change the tech stack to three.js or BabylonJS due to their high compatibility with the web ecosystem. I want to know which engine/library/framework we should use for the development of our 3d web application. Also with unity webgl, we want to develop all UI parts in web technologies only and will use the unity3d for 3d part only.

Points that are very important to consider - 1. Memory optimization and allocation 2. Quality 3. Shaders 4. Materials 5. Lighting 6. Mesh editing, mesh creation at runtime 7. Ar 8. Vr 10. Support on different browsers including mobile browsers 11. Physics(gravity, collision, cloth simulation, etc.) 12. Initial load time 13. Speed and performance 14. Max vertices count. What happens when we load models exceeding max vertex count? 15. Development time 16. Learning curve (Unity3d we already working on) 17. Ease of use. What artists can do using any platform eg. in unity3d, artists can edit materials, set up lighting etc? 18. Future scope 19. Scalability 20. Integration with web ecosystem

I want a advice on what to use as a beginner three.js or WebGL?
