bump mapping

i’ve sorta read the tutorial at nehe about bump mapping but that tells you how to do it
can give me a simpler explain of what bump mapping is?
thanx

the nehe tutorail aint proper bumpmapping i believe thats emboss bumpmapping,
bumpmapping is prolly one of the most discussed/explained topics in cg, try the nvidia website for a few pages (its not simple to understand so dont expect to straight away)

oh ok so what exatly is emboss bumpmapping???
and what is the address for the nvidia website???
thanx

Not really hard to explane, in the simplist terms it is using a image to map out raised areas on you object(making a 2D texture 3D) in which a texture is applied to.
