Computer graphics

Computer graphics have become an essential component of every architectural visualisation. The 3D computer graphics use a three dimensional representation of a geometric data. It is a mathematical representation of a three dimensional object. The process of 3D modeling describes the process of creating the shape of the object. The 3D models are created with the aid of modeling tools in the computer by an artist or an engineer.

They are scanned from a real object. A model is formed from vertices in the form of a polygon. The models can also be created by physical simulation. The layout of the object in a scene is imperative prior to rendering it into an image. Animation defines the object such as motion. Rendering transforms the model into an image by simulating light transport to obtain photo-realistic image a non photo-realistic image is obtained by applying an art style. In the process of rendering, two operations are transport and scattering using 3D computer graphics software. The computer graphics which to be 3D are not all based on wireframe model. 2D computer graphics with 3D photorealistic effects can be achieved without using wireframe model. There is some graphic art software with filters which can be applied to 2D vector graphics.

Visual artists can copy 3D effect and render photorealistic effects without using filters. These 3D computer graphics are increasingly being used in architectural visualizations. These complex processes and software’s succeed in producing realistic visualizations of large buildings and towers even before the first brick has been laid. The investors and designers do not have to pore over sketches and technical papers but can get an image which seems real. It is also an effective way to attract customers to buy say a flat. The 3D visualizations are often seen in the advertisements.
