Mesh representation is a method used in computer graphics and 3D modeling to describe the shape of an object. It consists of vertices, edges, and faces that together form a network, or "mesh," which defines the object's surface. This representation allows for detailed modeling of complex shapes and is widely used in applications like video games, animations, and simulations. In addition to graphics, mesh representation is also important in fields like finite element analysis and computer-aided design (CAD). It enables engineers and designers to analyze physical properties and behaviors of structures by breaking them down into smaller, manageable parts. This approach enhances accuracy and efficiency in various engineering applications.
