Kerkythea is a completely free, high-quality and fast 3D models render for Windows, Mac OS X and Linux platforms, developed by Ioannis Pantazopoulos from Greece. I found this free render engine in the process of studying SketchUp (by reading Architectural Design with SketchUp). In the end, it passed the software quality audit of AppNee, thus can be shared with more users around the world. Although it is a free software and not as popular as other renders, the functions of Kerkythea are not inferior in any respect. To some extent, it can be a preferred rendering tool for many small companies.
