Mesh simplification is a process used in computer graphics to reduce the complexity of 3D models. This technique involves decreasing the number of polygons in a mesh while preserving its overall shape and appearance. By simplifying the mesh, it becomes easier to render, which can improve performance in applications like video games and virtual reality. The primary goal of mesh simplification is to maintain visual fidelity while minimizing computational load. Various algorithms, such as Quadric Error Metrics and Vertex Clustering, are employed to achieve this balance. These methods help create efficient models that are suitable for real-time rendering and other applications.
