Description: Vertex lighting is a technique used in computer graphics that calculates lighting at each vertex of a 3D model. This method relies on interpolating lighting values across the surfaces of the model, allowing for a more efficient and faster representation of light compared to pixel lighting, which calculates light for each individual pixel. Vertex lighting is particularly useful in applications where performance is critical, such as in video games and real-time simulations. By calculating lighting at the vertices, computational load is reduced, enabling more polygons to be processed and maintaining a higher frame rate. However, this technique can result in a lower level of detail in lighting, as interpolation may smooth out light and shadow effects, which can be less realistic in complex scenes. Despite its limitations, vertex lighting remains a valuable tool in the rendering techniques arsenal, especially when combined with other advanced lighting techniques to achieve a balance between performance and visual quality.
