  2. Cube mapping - Wikipedia

    en.wikipedia.org/wiki/Cube_mapping

    In computer graphics, cube mapping is a method of environment mapping that uses the six faces of a cube as the map shape. The environment is projected onto the sides of a cube and stored as six square textures, or unfolded into six regions of a single texture. The cube map is generated by first rendering the scene six times from a viewpoint ...

  3. Texture mapping - Wikipedia

    en.wikipedia.org/wiki/Texture_mapping

    Texture mapping. Mapping a two-dimensional texture onto a 3D model. 1: 3D model without textures. 2: Same model with textures. Texture mapping [1] [2] [3] is a method for mapping a texture on a computer-generated graphic. Texture here can be high frequency detail, surface texture, or color .

  4. Hyperspectral imaging - Wikipedia

    en.wikipedia.org/wiki/Hyperspectral_imaging

    From left to right: Slit spectrum; monochromatic spatial map; 'perspective projection' of hyperspectral cube; wavelength-coded spatial map. There are four basic techniques for acquiring the three-dimensional (x, y, λ) dataset of a hyperspectral cube. The choice of technique depends on the specific application, seeing that each technique has ...

  5. Reflection mapping - Wikipedia

    en.wikipedia.org/wiki/Reflection_mapping

    Reflection mapping. In computer graphics, reflection mapping or environment mapping [1] [2] [3] is an efficient image-based lighting technique for approximating the appearance of a reflective surface by means of a precomputed texture. The texture is used to store the image of the distant environment surrounding the rendered object.

  6. Normal mapping - Wikipedia

    en.wikipedia.org/wiki/Normal_mapping

    Normal mapping used to re-detail simplified meshes. This normal map is encoded in object space. 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. It is used to add details without using more polygons.

  7. Cubic graph - Wikipedia

    en.wikipedia.org/wiki/Cubic_graph

    Cubic graph. The Petersen graph is a cubic graph. In the mathematical field of graph theory, a cubic graph is a graph in which all vertices have degree three. In other words, a cubic graph is a 3- regular graph. Cubic graphs are also called trivalent graphs . A bicubic graph is a cubic bipartite graph .

  8. UV mapping - Wikipedia

    en.wikipedia.org/wiki/UV_mapping

    UV mapping. The application of a texture in the UV space related to the effect in 3D. A representation of the UV mapping of a cube. The flattened cube net may then be textured to texture the cube. UV mapping is the 3D modeling process of projecting a 3D model's surface to a 2D image for texture mapping. The letters "U" and "V" denote the axes ...

  9. Bicubic interpolation - Wikipedia

    en.wikipedia.org/wiki/Bicubic_interpolation

    In mathematics, bicubic interpolation is an extension of cubic spline interpolation (a method of applying cubic interpolation to a data set) for interpolating data points on a two-dimensional regular grid. The interpolated surface (meaning the kernel shape, not the image) is smoother than corresponding surfaces obtained by bilinear ...
