Initially, architectural renderings was limited only to hand painted art work. It is now more commonly known for Architectural Illustration of Architectural rendering. Although the words are the same, the process of 3D architectural rendering has brought a big change in itself. Hand architectural rendering are set up accordingly and they are colored and lit on a flat surface. In the case of Digital architectural rendering, they are set up as virtual reality scenes using a computer and with complex calculations an image is been created. The process involved in these calculations is called “rendering. In old days, a traditional architectural rendering was an important service and was available for high quality artwork. It was difficult to find a good illustrator in that period. Also, architectural renderings were hard to alter. They were found to be hard to alter. They were found to be inaccurate, But it reflect the real concept of architectural approach.

Today it is very common to see Digital based architectural rendering and artwork being prepared. Computer generated image became known in the early 1990’S. 3d was considered to be a new (upcoming) technology. At that time, a computer generated image took more time to prepare an architectural image than renderings created by hand. Also, the result was found to be dull and stale, irrespective of the operator’s skill. The main reason behind this was in the mid 1990’S that one could see technology improving and so it was possible to combine 3D and hand painted artwork to achieve more flexibility, accuracy and thus making the image realistic enough.

It was only in the late 1990’S that people started taking 3D architectural renderings and rendering seriously. 3D now became viable, not only to traditional rendering but also towards real photography. Today’s 3D rendering artist is considered as a specialist. A 3D rcomputer generated  architectural rendering  image concept involves animators, modelers, character animators, texture/material builders, lighting experts and IT personnel are also considered to be important since they are responsible for keeping the hardware running. Hardware was considered as the biggest issue to tackle in order to get realistic 3D renderings on time and to an acceptable quality. For the want of a nice looking rendering, one must know that more processing power is needed. In the beginning, the speed of hardware was critical. But later on, computers got faster and there was an improvement found which benefited the main stream business, artists and home users. The advances brought in 3D rendering hardware, opened doors for new techniques to enter. Artists accepted new hardware technology as a blessing for them. If one has a big desire for creating pure realistic images then one must see that they try to push the limits of hardware and software constantly.

Today, most of the printed publications, recommend high quality 3D Architectural renderings. Digital architectural rendering flourished into a fast growing industry due to it’s demand,.Computer generated architectural or Architectural Digital Rendering (ADR) improve much further as the technology improves further. But because of their artistic abilities. Both will survive and stay.
