A 3D computer graphics modeler uses specialized computer software to render objects from the physical world in a three-dimensional, virtual environment. 3D modeling is employed in many fields, from game development to medical graphics to special effects in filmmaking to engineering and architecture. In Twinity, 3D modelling is used to design small objects such as furniture, clothing and hairstyles as well as the entire visible environment of the Twinity virtual world, including avatars. The process of modeling an object in 3D space requires the modeler to use a mathematical, wireframe mesh, which is used to connect points in space via polygons, to design and model the object as closely as possible to its real-world counterpart. The Twinity virtual world is constructed using 3D modeling software programs such as 3ds Max (formerly 3D Studio MAX).
