Rhinoceros 3D - Rhino
Rhinoceros geometry is based on the NURBS mathematical model, which focuses on producing mathematically precise representation of curves and free form surfaces in computer graphics (as opposed to polygon mesh-based applications).
Rhinoceros is used in processes of computer-aided design (CAD), computer-aided manufacturing (CAM), rapid prototyping, 3D printing and reverse engineering in industries including architecture, industrial design (e.g. automotive design, watercraft design), product design (e.g. jewelry design) as well as for multimedia and graphic design.
