Texture map refers to a Raster graphics also called image, texture. If the texture stores a specific property it's also referred to as color map, roughness map... The coordinate space which converts from the 3D space of a 3D model into a 2D space so that it can sample from the Texture map is called: UV Space, UV Coordinates, Texture Space.
In computer graphics, a texel, texture element, or texture pixel is the fundamental unit of a texture map. [1] Textures are represented by arrays of texels representing the texture space, just as other images are represented by arrays of pixels. Texels can also be described by image regions that are obtained through simple procedures such as ...
Texture units in a video card take a texture and 'map' it to a piece of geometry. That is, they wrap the texture around the geometry and produce textured pixels which can then be written to the screen. Textures can be an actual image, a lightmap, or even normal maps for advanced surface lighting effects.
When the scene is rendered, each triangle will map to the appropriate texture from the "decal sheet". A UV map can either be generated automatically by the software application, made manually by the artist, or some combination of both. Often a UV map will be generated, and then the artist will adjust and optimize it to minimize seams and overlaps.
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 and wrinkles on the surface of an object.
Cube maps provide a fairly straightforward and efficient solution to rendering stable specular highlights. Multiple specular highlights can be encoded into a cube map texture, which can then be accessed by interpolating across the surface's reflection vector to supply coordinates. Relative to computing lighting at individual vertices, this ...
Polynomial texture mapping may be used for detailed recording and documentation, 3D modeling, edge detection, and to aid the study of inscriptions, rock art [5] and other artefacts. [ 3 ] [ 6 ] It has been applied to hundreds of the Vindolanda tablets by the Centre for the Study of Ancient Documents at the University of Oxford in conjunction ...
A Least squares conformal map (LSCM) is a 2-D representation of a 3-D shape created using the Least Squares Conformal Mapping Method. [ circular definition ] By using the map as a guide when creating a new 2-D image, the colors of the 2-D image can be applied to the original 3-D model.
