Accurate, life like illustration of architectural projects serves two very important functions. First, it keeps expectations in line with what can be acomplished. Clients who get what they expected are happier than those who don’t. Also, it greatly enhances the client’s understanding of the project. It allows more meaningful feedback from the client and from the public. Better input to a project results in better function, and better architecture. People see more and react differently to a more realistic rendering than they do to a more artistic one.
