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 ...
When computing Worley noise, each seed is located within its own grid square. (Grid is not a part of the noise) Worley noise can be differentiated once to generate a normal map. (Grid is not a part of noise) Worley noise, also called Voronoi noise and cellular noise, is a noise function introduced by Steven Worley in 1996.
PNG is a lossless, truecolor image format. It is good for all maps and particularly for maps with more than 256 colours. As a pixel-based image, it is more difficult than an SVG image to edit. Some uploaders prefer to work with SVG and then upload a PNG version. SVG is vector graphics format, which has three main advantages:
Generic Mapping Tools (GMT) are an open-source collection of computer software tools for processing and displaying xy and xyz datasets, including rasterization, filtering and other image processing operations, and various kinds of map projections.
Category:Wikipedia maps - for map work, help, templates, etc.. Portal:Atlas/ Wikimedia Atlas; Upload, to upload your free work. When adding maps to articles, you have two options; you can add a separate map, or add a geo-referenced template that links to several maps depending on the reader's preference. Blank resources
The lower left image shows a scene with a viewpoint marked with a black dot. The upper image shows the net of the cube mapping as seen from that viewpoint, and the lower right image shows the cube superimposed on the original scene. In computer graphics, cube mapping is a method of environment mapping that uses the six faces of a cube as the ...

The other method is to specify a normal map which contains the modified normal for each point on the surface directly. Since the normal is specified directly instead of derived from a height map this method usually leads to more predictable results. This makes it easier for artists to work with, making it the most common method of bump mapping ...
