![]() ![]() They are much more accurate because they not only simulate that the pixel is along a line away from the face, but can also simulate that the pixel is moved in any direction and in any way. ![]() These are images that store the direction of the normal directly in the RGB values of an image. You can use either grayscale images or the intensity values of an RGB texture (including images). (The “dent” consists only of a displacement that takes place along the existing and unchanged normal vector of the surface). The pixels seem to be shifted by the required distance towards the area normal. These are textures that store an intensity, the relative height of pixels from the camera’s point of view. ![]() Although the terms normal and bump map are often used synonymously, there are certain differences. Both bump and normal maps work by changing the normal angle (the direction perpendicular to a surface), which affects the shading of a pixel. ![]()
