Architecture: One of the purposes for the development of virtual reality (that is in fact a form of computer animation) was which it was going to be very helpful to architects. Here, that has proved to be exact. A person can hire an architect half way across the world over the Internet or the other network. The architect can design a house and build a walkthrough animation of the house. This will show the customer what the house will in reality look like before anyone lays a hand on a hammer to construct it.
Computer animation can also be useful to architects hence they can observe any flaws in their designs. It has proved to be much cost and time saving since no one has to build anything. It is one field, wherein computer animation has proved to be very helpful.
