Procedural textures are defined in 3D space and to recover the texture value at a given point of the surface the point coordinate in 3D space are used.

THere are, on the other hand, some inherently 2D texture, and these deserve special mappings. Here we will describe the simpler, the following chapter will go in detail on the more complex and flexible ones

=ImageTexture=
The Image texture is the only true 2D texture, and is the most frequently
used and most advanced of Blender's textures. The standard, built-in
bump mapping and perspective-corrected mip-mapping, filtering, and
anti-aliasing guarantee outstanding images (set DisplayButtons
{{Literal|OSA}} to
ON for this). Because pictures are two-dimensional, the way in which
the 3D texture coordinate is translated to 2D must be specified in the
''mapping'' buttons (''Texture mapping'').
The four standard mappings are: {{Literal|Flat}},
{{Literal|Cube}},
{{Literal|Tube}} and {{Literal|Sphere}}. Depending on the
overall
shape of the object, one of these types is more useful.
[[Image:Manual-Part-IV-FlatMap.png|frame|none|Flat Mapping. ]]
The Flat mapping (''Flat Mapping. '') gives the best
results on single planar faces. It does produce interesting effects on the
sphere, but compared to a
sphere-mapped sphere the result looks flat. On faces not in the mapping
plane
the last pixel of the texture is repeated, which produces stripes on
the cube and cylinder.
[[Image:Manual-Part-IV-CubeMap.png|frame|none|Cube Mapping. ]]
The cube-mapping (''Cube Mapping. '') often gives the
most useful
results when the objects
are not too curvy and organic (notice the seams on the sphere).
[[Image:Manual-Part-IV-TubeMap.png|frame|none|Tube Mapping. ]]
The tube-mapping (''Tube Mapping. '') maps the texture
around an object like a label on a
bottle. The texture is therefore more stretched on the cylinder. This
mapping is of course very good for making the label on a bottle or
assigning stickers to rounded objects. However, this is not a cylindrical
mapping so the ends of the cylinder are undefined.
[[Image:Manual-Part-IV-SphereMap.png|frame|none|Sphere Mapping. ]]
The sphere-mapping (''Sphere Mapping. '') is the best type
for mapping a
sphere, and it is perfect for making a planet and similar stuff. It
is often very useful for creating organic objects. It too produces
interesting effects on a cylinder.

{{Note|Moving a texture|
As described in the previous section you can manipulate the texture in
the texture part of the MaterialButtons. There is one more important
feature to manipulate the textures.
When you select an object and press {{Shortcut|T}}, you get the
option to
visually scale and move the texture space, but not to rotate the
texture. The {{Literal|Object}} coordinate mapping is anyway much
more flexible.
