Texture mapping is a technique for adding
detail to 3D geometry (or objects) by using an
Surface texture, Colour, Transparency,
Bump mapping is a method of simulating
bumps and wrinkles on to the surface of an
object. The surface of the underlying object is
not actually changed.
Normal Mapping is the most common variation of
bump mapping used. It is a technique used for
faking the lighting of bumps and dents.
A common use of this technique is to take a low
resolution model and using tricks to make it look
like a higher resolution.
Parallax mapping (also
called offset mapping or
mapping) is an
enhancement of the
At steeper view-angles,

Displacement mapping is an
alternative technique that uses

It gives surfaces a great sense

shadowing and silhouettes;
It is the most costly of this class
