What's the difference from normal mapping and bump mapping?

What’s the difference from normal mapping and bump mapping?
I took a peek at wikipedia’s article, but I’m not really understanding if this is any better than bump mapping.

Bump map only have one vector. The input is grayscale, as height.
Normal map play with normal of each pixel of a face. the input is a RGB image where each channel drive a vector(in x,y,z) so you can drive virtually your pixel around, giving not only height to your texture, but also a direction.

Oh! I get it. So if you want your bump map to go up in one place, and in another place you want it to go left, you use normal mapping.

eh, it just looks better at all angles. But blender does not render them correctly yet… if ever :stuck_out_tongue: Comeon some one pleazse fix this :smiley:

I agree 100% If this gets fixed, I will immediatley go and purchase Zbrush and utilize it in my workflow.
