Hello,

For intersection testing, you can use the chapter 13 of the getting started
guide (intersection tetsing) or the chapter 4 of the programmer's guide.
If you need more real code, you can contact me.

Cheers,

Objet : Get Image/Scene Informations ...

Hi,
i have two question for the perfomer GURUS,on getting Image
Informations.

1. How can i get the color/brightness of a pixel in the outputwindow ?
   (maybe by graficcontext or by window ..?)

2. I would like to set a "unvisible virtual beam" from a position into a
certain direction and
   would like to know which objects are hit by the beam ?
   (via Intersectiontesting ...? )

thanks for your tips

Daniel
