A checkered sphere, without (left) and with (right) UV mapping (Using 3D XYZ space or 2D UV space). In the example to the right, a sphere is given a checkered texture in two ways. On the left, without UV mapping, the sphere is carved out of three-dimensional checkers tiling Euclidean space.
For use with modern hardware, texture map data may be stored in swizzled or tiled orderings to improve cache coherency. Rendering APIs typically manage texture map resources (which may be located in device memory ) as buffers or surfaces, and may allow ' render to texture ' for additional effects such as post processing or environment mapping .
A variety of techniques including ambient occlusion, direct lighting with sampled shadow edges, and full radiosity [4] bounce light solutions are typically used. Modern 3D packages include specific plugins for applying light-map UV-coordinates, atlas-ing multiple surfaces into single texture sheets, and rendering the maps themselves.
An environment texture mapped onto models of spoons, to give the illusion that they are reflecting the world around them. 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.
[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. LSCM is used in computer graphics as a method of producing a UV map from a polygonal mesh to a texture map such that the shape of the polygons as mapped to the texture is relatively undistorted.
UVW mapping is a mathematical technique for coordinate mapping. [1] In computer graphics, it most commonly maps an object's surface in to a solid texture with UVW coordinates in , in contrast to UV mapping, which maps surfaces in to an image with UV coordinates in .
To use this data, the surface normal of the object, view direction from the object to the camera, and/or reflected direction from the object to the environment is used to calculate a texture coordinate to look up in the aforementioned texture map. The result appears like the environment is reflected in the surface of the object that is being ...
A bitmap image/rendering resource used in texture mapping, applied to 3D models and indexed by UV mapping for 3D rendering. Texture space The coordinate space of a texture map, usually corresponding to UV coordinates in a 3D model. Used for some rendering algorithms such as texture space diffusion Transform feedback
