On curved surfaces it is more easily noticeable that you don't create real 3D structures. They work well on flat surfaces, only to some extent on curved surfaces. Image 1c: The texture grid applied to a sphere and to a plane.īump Maps are easy to apply. Image 1b: Material settings for the texture.
Image 1a: A texture grid for bump mapping. You may either use greyscale pictures or the intensity values of an RGB-Texture (including images). The pixels seem to be moved in the direction of the facenormals, either in direction to or away from the camera.
'Landscape Modeling III: Exporting as a Heightmap'īump Maps are textures that store the relative height of pixels from the viewpoint of the camera.
