Correlation between model complexity and production time


The level of detail and complexity of 3D models are primarily determined by their intended application. For instance, certain city models or buildings require a high degree of precision, while simpler representations may suffice for others. As the complexity of the model varies, so does the amount of work involved in creating it. To provide context, we've included examples of 3D building models at varying levels of complexity, along with the average time needed to generate each one.
