  2. Projection mapping - Wikipedia

    en.wikipedia.org/wiki/Projection_mapping

    Projection mapping, similar to video mapping and spatial augmented reality, is a projection technique [1] [2] used to turn objects, often irregularly shaped, into display surfaces for video projection. The objects may be complex industrial landscapes, such as buildings, small indoor objects, or theatrical stages.

  3. UV mapping - Wikipedia

    en.wikipedia.org/wiki/UV_mapping

    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 of the 2D texture because "X", "Y", and "Z" are already used to denote the axes of the 3D object in model space, while "W" (in addition to XYZ) is used in calculating quaternion rotations, a common ...

  4. Rapid 3D Mapping - Wikipedia

    en.wikipedia.org/wiki/Rapid_3D_Mapping

    Rapid 3D Mapping applied on the Royal Castle of Sweden. Rapid 3D Mapping is a stereophotogrammetry technology developed by the Swedish defence and security company Saab.The system generates three-dimensional maps by image captures of the terrain from a crewed aircraft, helicopter and/or UAV.

  5. 3D projection - Wikipedia

    en.wikipedia.org/wiki/3D_projection

    3D projections use the primary qualities of an object's basic shape to create a map of points, that are then connected to one another to create a visual element. The result is a graphic that contains conceptual properties to interpret the figure or image as not actually flat (2D), but rather, as a solid object (3D) being viewed on a 2D display.

  6. Texture mapping - Wikipedia

    en.wikipedia.org/wiki/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" in this context can be high frequency detail, surface texture, or color.

  7. Google Earth - Wikipedia

    en.wikipedia.org/wiki/Google_Earth

    Google Earth is a web and computer program that renders a 3D representation of Earth based primarily on satellite imagery.The program maps the Earth by superimposing satellite images, aerial photography, and GIS data onto a 3D globe, allowing users to see cities and landscapes from various angles.

  8. 3D scanning - Wikipedia

    en.wikipedia.org/wiki/3D_scanning

    3D data acquisition and object reconstruction can be performed using stereo image pairs. Stereo photogrammetry or photogrammetry based on a block of overlapped images is the primary approach for 3D mapping and object reconstruction using 2D images.

  9. Heightmap - Wikipedia

    en.wikipedia.org/wiki/Heightmap

    A heightmap created with Terragen The same heightmap converted to a 3D mesh and rendered with Anim8or. In computer graphics, a heightmap or heightfield is a raster image used mainly as Discrete Global Grid in secondary elevation modeling. Each pixel stores values, such as surface elevation data, for display in 3D computer graphics.
