A texture map (left). The corresponding normal map in tangent space (center). The normal map applied to a sphere in object space (right). Normal map reuse is made possible by encoding maps in tangent space. The tangent space is a vector space, which is tangent to the model's surface. The coordinate system varies smoothly (based on the ...
In creating geographical maps for Wikipedia, it is often useful to have high-quality source material such as blank outline maps, Adobe Photoshop or GIMP-format images with layers, SVG files and so on. If you have such source material that you think may be helpful to other map authors, please feel free to upload it to Wikipedia and list it here.
Bump mapping [1] is a texture mapping technique in computer graphics for simulating bumps and wrinkles on the surface of an object. This is achieved by perturbing the surface normals of the object and using the perturbed normal during lighting calculations. The result is an apparently bumpy surface rather than a smooth surface, although the ...
UV texturing permits polygons that make up a 3D object to be painted with color (and other surface attributes) from an ordinary image. The image is called a UV texture map. [ 1 ] The UV mapping process involves assigning pixels in the image to surface mappings on the polygon, usually done by "programmatically" copying a triangular piece of the ...
The Maps for Wikipedia page is an overview of different formats and tools for maps available on Wikipedia. The Map conventions page provides advice for creating and improving maps. The Map workshop page can be used to add your map requests and your sources. A graphist will create the requested map.
[26]: 9.1.1 [40] After 3D coordinates have been projected onto the image plane , rasterization is primarily a 2D problem, but the 3rd dimension necessitates hidden surface removal . Early computer graphics used geometric algorithms or ray casting to remove the hidden portions of shapes, or used the painter's algorithm , which sorts shapes by ...
A texture map [5] [6] is an image applied (mapped) to the surface of a shape or polygon. [7] This may be a bitmap image or a procedural texture . They may be stored in common image file formats , referenced by 3D model formats or material definitions , and assembled into resource bundles .
