Features: Learning sketching usually begins with understanding geometric shapes. Recognizing and learning to draw plaster geometric forms is the initial stage of sketching. Among all objects, geometric shapes are the simplest. Common geometric shapes include: cubes, cones, spheres, polyhedrons, and spheres, etc. On one hand, these shapes are simple and have distinct features, making them relatively easy to master. On the other hand, these shapes also broadly represent 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 at art supply stores. They are generally divided into two categories: Simple ones, such as: cubes, rectangular prisms, cylinders, triangular pyramids, hexahedrons, and spheres, etc.; Complex ones, such as: oblique cylinders, dodecahedrons, cube-cone combinations, combined forms of two rectangular prisms, cone-cylinder combinations, 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 highlight their color characteristics.
