According to the Bureau of Labor Statistics' Occupational Outlook Quarterly, 3D modelers build 3D characters and environments that are based on the concept art. To create the models’ surfaces or skins, they paint and wrap 2D textures on a digital frame. Modelers also create character skeletons, which animators then control. Modeling is performed using a variety of programs such as Maya, 3DS Max, Pixar's RenderMan, POV-Ray, and many others.
