3D architectural renderings bring 2D drawings and sketches to life in a realistic and accurate way. Visual technologies have advanced to allow realistic lighting and shadow effects, life-like trees and landscaping - resulting in 3D CAD renderings that can be difficult to tell from real photos. Computer generated architectural rendering offers many benefits over traditional watercolour renderings, including flexibility, realism, the ability to view the site from all angles and the ease of making revisions.
