3DCoat (AKA: 3D-Coat) is a digital sculpturing software (from Ukraine) that is specially designed for the art design work (i.e., details design) of game models. It not only integrates various real-time 3D model texture mapping and detail sculpture functions in one place, but also supports topology, volume sculpture, hardware rendering, and other important features. Moreover, it uses the normal mapping as window display technique, which greatly accelerates the speed to view and edit objects.
