Architectural visualisation are the two dimensional images or an animation showcasing an architectural design. The visualizations can be created using computers called as the computer generated renderings. The computer uses a 3D modeling software to create the visualization. There are sophisticated software available which can emulate the lighting and also the buildings. They are called as photo real rendering. The purpose of the visualizations can vary from presentation to marketing of analysis of design. The renderings can be still, a three dimensional fly by or a walk, floor plans, photo realistic 3D renderings, virtual tours, a panoramic view rendering. The renderings are useful for big real estate projects which allow the architects to dwell upon the design of the proposed building and implement any alteration required to be made to the project. The visual impact is also assessed.
The traditional method of creating the renderings was by hand. With the advent of computers this underwent a paradigm shift, but there are many architects who use their hands to create visualization even today. Many use a combination of computers and hand to create them. The common tools for making visualization by hands are markers, pen, color pencil, water colors and acrylic. Hugh Ferriss Memorial Prize is an award by the American Society of Architectural Illustrators which is presented to honor excellence in graphic presentation of architecture. In the past these techniques were taught in a master class where the student worked with the teacher of fine arts. The architects use sketches, pens and inks and water colors to compose their renderings. Computer generated graphics is a useful and highly effective medium of presenting the visualizations. These are increasingly being used
