Features: Learning sketching usually starts with recognizing geometric solids. Recognizing and learning to draw plaster geometric forms is the initial stage of sketching. Among all objects, the shapes of geometric solids are the simplest. Common geometric solids include: cubes, cones, cylinders, polyhedrons, and spheres, etc. On one hand, these forms are simple in shape and have distinct features, making them relatively easy to master. On the other hand, these forms also basically summarize the shape characteristics of various objects encountered in daily life. When learning sketching, plaster geometric forms are typically chosen as subjects. Common plaster geometric forms can usually be purchased from art supply stores. They are generally divided into two categories: Simple ones, such as: cubes, rectangular prisms, cylinders, triangular pyramids, hexahedrons, spheres, etc.; Complex ones, such as: oblique cylinders, dodecahedrons, cube-cone composite forms, combined forms of two rectangular prisms, cone-cylinder composite forms, etc. Plaster geometric forms are white. Therefore, when rendering them, it is not only necessary to accurately depict their external shape and perspective features but also, when using chiaroscuro techniques, to typically portray their color characteristics.
