Sculptris is a virtual sculpting software program, with a primary focus on the concept of modeling clay. It has been actively developed since early December 2009. Users can pull, push, pinch, and twist virtual clay. It is geared toward character sculpting and “organic” models. 3D meshes (.obj) can be imported into the program for further detailing, generating normal and displacement maps. In late July 2010, Sculptris inventor Tomas Pettersson joined the Pixologic team (makers of ZBrush), who have taken over Sculptris development.
