Shape modeling is a research area within computer graphics and computer-aided design that focuses on the representation and manipulation of geometric shapes and objects. This includes the development of algorithms and techniques for creating, editing, analyzing, and rendering shapes in 2D and 3D environments. Shape modeling is used in a variety of applications, such as virtual reality, animation, industrial design, and medical imaging. Researchers in this field work to improve the efficiency, accuracy, and realism of shape representation and manipulation in digital environments.
