Ok, I got it. Bump map contains only z value, a heightmap. Normal map is another tex. For example red color means x coord, green y coord and blue coord is the z coord of the normal vector. Every pixel of a texture with a normal map contains a normal vector.

Can a normal map only be used for static objectes?
And do you use this together with a light map?

Normal maps can be used by dynamic objects. You just need to transform the normal from your normal map by the same rotation that you used to transform the original object in the first place.

And yes, you can use it with a light map.
