Irrlicht Engine

i was wondering if anyone wanted to know how to do this before i wrote up a tutorial. although i have seen many posts on this problem and i wanted to end it once and for all. so you dont have the expense of physics nor the glitchiness of irrlicht's collision with terrain. this is very simple so i wanted to know.

EDIT: here it is:

okay look at :

for the tut!

yes but i found for some reason getHeight alone looked very bad on my terrain since my terrain was huge.so this smooths it back out.
