What is Unity?

Unity is a versatile game development engine. It is primarily known for game development that offers various tools and features for developing 2D and 3D games. Additionally, we can use it for various types of application development purposes, such as,

Augmented reality (AR) and Virtual Reality (VR) application development
Interactive Multimedia Applications such as interactive storytelling experiences, interactive exhibitions of museums, and interactive marketing presentations.
Unity is suitable for creating interactive multimedia applications, such as interactive art installations, Interactive simulations for education, healthcare, and training. For example, virtual laboratories, physics simulations, medical training scenarios, and virtual tours.

Beyond the entertainment games, we can develop Games for education, healthcare, and corporate training.

Furthermore, we can use Unity for 3D Visualizations such as architectural, product showcases, interior design previews, and data visualizations.

Additionally, we can use it for mobile application development and cross-platform application development, such as we can build applications that can run on multiple platforms, including desktops (Windows, macOS, Linux), mobile devices, consoles, and web browsers.

Now, let’s go for prerequisites and development environment setup.
