![]() You may either use grayscale pictures or the intensity values of an RGB texture (including images). ![]() (The “bump” consists only of a displacement, which takes place along the existing,Īnd unchanged, normal vector of the face). The pixels seem to be moved by the required distance in the direction of the face normals. Bump maps These are textures that store an intensity, the relative height of pixels from the viewpoint of the camera. Synonymously, there are certain differences. (the direction pointing perpendicular from a face), which influences how a pixel is shaded.Īlthough the terms Normal Map and Bump Map are often used You will notice that the surface is not really shaped.īoth Bump Maps and Normal Maps work by modifying the normal angle If the camera angle is too flat to the surface, This will not cast any shadows and will not obstruct other objects. They simulate the impression of a detailed 3D surface,īy modifying the shading as if the surface had lots of small angles, rather than being completely flat.īecause it is just modifying the shading of each pixel, Normal Maps and Bump Maps both serve the same purpose:
