To create a 3D world in a game engine, you will need to use a game engine that has 3D capabilities. Some popular game engines that support 3D game development include Unity, Unreal Engine, and CryEngine. To create a 3D world, you will need to use the tools and features provided by the game engine to create and model 3D objects, terrain, and other elements. This can involve using 3D modeling software to create and export 3D models, and using the game engine’s level editor or other tools to place and arrange the models in the game world. You will also need to use the game engine’s scripting and programming tools to create gameplay mechanics, AI behaviors, and other interactive elements.

There are several ways to create an AR (augmented reality) application, but the easiest way will depend on your specific needs and goals. One approach is to use an AR platform or toolkit that provides pre-built components and features that you can use to quickly build an AR application. These platforms typically require little or no programming experience, and provide user-friendly tools and interfaces for creating AR experiences. Some popular AR platforms include ARKit, ARCore, and Vuforia. Another way to create an AR application is to use a game engine, such as Unity or Unreal Engine, which provide support for AR development and come with a range of tools and features for creating interactive AR experiences.
