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 ...
Filter Forge also includes rendering options such as anti-aliasing, bump maps and normal maps, environment mapping, ambient occlusion, seamless tiling, and a text-based batch renderer. Users can randomize or control specific parameters of each filter through sliders, color pickers, and checkboxes. Sets of parameter values can be saved as presets.
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 ...
Normal coordinates exist on a normal neighborhood of a point p in M. A normal neighborhood U is an open subset of M such that there is a proper neighborhood V of the origin in the tangent space T p M, and exp p acts as a diffeomorphism between U and V. On a normal neighborhood U of p in M, the chart is given by:
MrSID (pronounced Mister Sid) is an acronym that stands for multiresolution seamless image database.It is a file format (filename extension.sid) developed and patented [2] [3] by LizardTech (in October 2018 absorbed into Extensis) [4] for encoding of georeferenced raster graphics, such as orthophotos.

3Dc (FourCC : ATI2), also known as DXN, BC5, or Block Compression 5 is a lossy data compression algorithm for normal maps invented and first implemented by ATI.It builds upon the earlier DXT5 algorithm and is an open standard. 3Dc is now implemented by both ATI and Nvidia.
Also, cube mapping uses the entire resolution of the texture image, compared to sphere and paraboloid mappings, which also allows it to use lower resolution images to achieve the same quality. Although handling the seams of the cube map is a problem, algorithms have been developed to handle seam behavior and result in a seamless reflection.
