Cube mapping is a technique that uses six faces of a cube as the map shape to project the environment onto. It is preferred over sphere mapping because it eliminates distortion, viewpoint dependency, and inefficiency.
Reflection mapping or environment mapping is a computer graphics method to approximate the appearance of a reflective surface by using a precomputed texture of the surrounding environment. Learn about different types of environment mapping, such as sphere mapping, cube mapping, and HEALPix mapping, and their history and applications.
Development of the quadrilateralized spherical cube projection on an Earth model [1] In mapmaking, a quadrilateralized spherical cube, or quad sphere for short, is an equal-area polyhedral map projection and discrete global grid scheme for data collected on a spherical surface (either that of the Earth or the celestial sphere).
The hemicube has been used in a number of other Light Transport algorithms, including the Progressive Radiosity algorithm and the Monte Carlo Radiosity algorithm. The hemicube can also be used for other purposes, such as environment mapping and reflection mapping. In some cases, a hemicube may be used in environment mapping or reflection mapping.
An equirectangular projection simply maps the yaw and pitch (longitude and latitude) of a sphere linearly to a rectangular image. It produces a signature curved look. In addition, the distribution of pixel density (which can be visualized with Tissot's indicatrix ) is suboptimal, with the usually more important "equator" getting the lowest density.
Equirectangular projection is a map projection that maps meridians to vertical lines and circles of latitude to horizontal lines. It is also called equidistant cylindrical projection or plate carrée projection and has various applications in thematic mapping and panoramic photography.
UV mapping is the 3D modeling process of projecting a 3D model's surface to a 2D image for texture mapping. Learn about the UV unwrapping technique, the UV coordinates, and the applications of UV mapping in computer graphics and digital sculpting.
Bump mapping is a technique in computer graphics to make a rendered surface look more realistic by simulating small displacements of the surface. Learn about the principles, methods and examples of bump mapping, and how it differs from displacement mapping and normal mapping.
