World modeling refers to the process of creating digital simulations of real-world environments or scenarios. Some synonyms for world modeling include digital twinning, virtual prototyping, and simulation-based design. Each of these terms emphasizes a slightly different aspect of the world modeling process. Digital twinning highlights the creation of an exact digital replica of a physical system, while virtual prototyping focuses on the use of simulated environments to test and refine designs. Simulation-based design encompasses a broader range of applications, including the modeling of complex systems and the exploration of alternative scenarios. Regardless of the specific term used, world modeling is an essential tool for engineers, designers, and scientists working in a variety of fields.
