A three-dimensional architectural modeling is the process of developing a mathematical representation of any three-dimensional surface of an object via specialized software. 3D Architectural Visualization is on the rise these days. Few years ago all we had were raw and unrealistic renderings, today we can hardly tell a 3D rendered image from a professional photograph. Every company has one category common that is advertising and marketing. It will often include costs for 3D visualization services. The product is called a 3D model. 3D Architectural Modeling helps us in visualizing the products or things in dvance. Photorealistic image rendering brings life to the models.
