Hard surface modeling is a 3D modeling technique used to create inanimate objects with smooth, static surfaces such as cars, armor, machines, and structures. It is widely used in science fiction and shooter video games because it is ideal for building weapons, robots, armor, machines, and structures. Hard surface models tend to have contrasting, clean colors, and minimalist rendering. There is no strict definition of what makes a model a “hard surface,” and it often depends on each person’s own definition. However, essentially, with hard surface modeling, you need a smooth geometric mesh with less small details than needed for organic elements such as animals. Hard surface modeling is mainly defined by the characteristics of an objects surfaces and its geometry. In contrast, organic modeling is used to create living or natural objects such as animals, people, plants, and trees, which have smoother flowing shapes and very few hard edges.
