Bent normals are a technique used in 3D rendering and computer graphics to improve the accuracy of ambient occlusion (AO) and other lighting effects. They work by storing a modified normal vector at each point on a surface, which is then used to compute the AO. This allows for more accurate and detailed shading, especially in areas with complex geometry. Bent normals can be precomputed and stored in a texture or computed on the fly using various algorithms.
