In the growing world of CGI and visual effects, 3D modelers try to approximate a certain realism by bringing what’s on the screen back off it. They use computer programs to create three-dimensional models for use in films, television or video games. These could include renderings of performers’ faces, fake animals, or any number of visual objects required for the context. But then, 3D modelers also find their skills useful in the medical field, where exact models, dummies and renderings of various body parts can be very useful for study. This may seem like a niche field, but it’s closely related, programming wise, to a number of graphics and animation disciplines.
