Architectural rendering

Architectural rendering, or architectural illustration, is the art of creating two-dimensional images or animations showing the attributes of a proposed architectural design.Images that are generated by a computer using three-dimensional modeling software or other computer software for presentation purposes are commonly termed 'Computer Generated Renderings'. Rendering techniques vary. Some methods create simple flat images or images with basic shadows. A popular technique uses sophisticated software to approximate accurate lighting and materials. This technique is often referred to as a 'Photo Real' rendering. Renderings are usually created for presentation, marketing and design analysis purposes.Architectural renderings are often categorized into 3 sub-types: Exterior Renderings, Interior Renderings, and Aerial Renderings.Until 3D computer modeling became common, architectural renderings were generated by hand. There are still architectural illustrators who create renderings entirely by hand, as well as illustrators who use a combination of hand drawing/painting and computer generated color and/or linework. Common mediums for hand-done architectural renderings include: watercolor, colored pencil, gauche, and graphite or charcoal pencil.Traditionally rendering techniques were taught in a 'master class' practice (such as the École des Beaux-Arts), where a student works creatively with a mentor in the study of fine arts. Contemporary architects use hand-drawn sketches, pen and ink drawings, and watercolor renderings to represent their design with the vision of an artist. Computer generated graphics is the newest medium to be utilized by architectural illustrators.
