Bump?Displacement?

[獅子王凱]

我想問下bump同displacement有乜分別架?
同埋有冇咩site有NURBS modelling 既online tutorials?

Bump is the illusion of bending lights, so that you can see bumping effects on plane surface.

displacement is base on the texture light and dark value to control the actual geometry up and down.

in other words. bump is not really bumping, instead displacement is.

To 獅子王凱:
U really wanna model in Max with Nurbs? Well.....too hard, why don't you model in some software else, like rhino or metasquoia?
Moreover, mapping in Nurbs model is a small problem U will encounter. But I've seen some TaiWan books teaching Nurbs modelling.

I agree, if you are making product design, NURBS is better, but that's all. If you want to make organic (e.g. human, monster...) or other models, use Editable Poly. It's extremely good and mature in max5 now! You will notice that Maya is now promoting their so-called "sub-division modeling".... it's just a tool that you can find in the early version of max.

Anyway, you can still use NURBS to create models. For learning (it's good) and you can model beautiful things (I know because I tried before).

Hope this help![/img]
