Mesh modeling is a technique used in 3D computer graphics to create objects by connecting points in a three-dimensional space. These points, known as vertices, are linked by edges to form faces, typically in the shape of triangles or quadrilaterals. This method allows artists and designers to build complex shapes and structures, making it essential in fields like video game design and animation. The resulting mesh can be manipulated and refined to achieve the desired appearance. Software tools like Blender and Maya are commonly used for mesh modeling, providing features that help in sculpting, texturing, and rendering 3D models for various applications.
