Since i cant code all these new function alone, Since I cant code all these new function alone,
i really need help to find the best way to provide I really need help to find the best way to provide
GRRLIB functions to all these new effets in this demo. GRRLIB functions to all these new effects in this demo.
With the help of the doc you can try also to find how it works, With the help of the doc you can try also to find how it works,
for exemple i didnt succes fully coded a specular position and direction.... for example I didn't success fully coded a specular position and direction...
So i repeat i need HELP !!! ;) So I repeat I need HELP !!! ;)
