Hello !

I create this image http://imgur.com/e6ICY.png .

1.For some reason, I want to know the information of polygons.These polygons are
on this cylinder and illuminated by reflex light from the ground.I want to know
information such as polygon coordinate , normal vector ...etc.

2.After I find those information,I want to change some properties of these
polygon,such as color or reflection.

So what source code I should modify to conquer above two questions?

Any suggestion would be OK!

Thanks a lot !
