The sphere with the bump map applied (right) appears to have a mottled surface resembling an orange. Bump maps achieve this effect by changing how an illuminated surface reacts to light, without modifying the size or shape of the surface. Bump mapping [1] is a texture mapping technique in computer graphics for simulating bumps
Parallax mapping is essentially a method by which rough or uneven surfaces on a 2D texture can be "pulled out" to take on the appearance of a 3D surface. Technically, this is implemented by displacing the texture coordinates at a point on the rendered polygon by a function of the view angle in tangent space (the angle relative to the surface ...
Normal map (a) is baked from 78,642 triangle model (b) onto 768 triangle model (c). This results in a render of the 768 triangle model, (d). In 3D computer graphics, normal mapping, or Dot3 bump mapping, is a texture mapping technique used for faking the lighting of bumps and dents – an implementation of bump mapping.
In computer graphics, relief mapping is a texture mapping technique first introduced in 2000 [1] used to render the surface details of three-dimensional objects accurately and efficiently. [2] It can produce accurate depictions of self-occlusion, self-shadowing, and parallax. [3] It is a form of short-distance ray tracing done in a pixel shader.
Affine texture mapping linearly interpolates texture coordinates across a surface, and so is the fastest form of texture mapping. Some software and hardware (such as the original PlayStation ) project vertices in 3D space onto the screen during rendering and linearly interpolate the texture coordinates in screen space between them.
Texture mapping or bump mapping is a technique adapted from Computer graphics that adds a layer of shaded texture to the shaded surface relief that imitates the look of the local land cover. [13] This texture can be generated in several ways: Texture substitution: Copying, abstracting, and merging remote sensing imagery of land cover. [14]

In computer graphics, mipmaps (also MIP maps) or pyramids [1] [2] [3] are pre-calculated, optimized sequences of images, each of which is a progressively lower resolution representation of the previous. The height and width of each image, or level, in the mipmap is a factor of two smaller than the previous level.
