hi
im doing a 3d engine in Delphi (only with the Api SetPixel)...i mean im doing EVERYTHING..... and i draw it pixel per pixel!
and im doing some test..in DB...to understand how i should do it.. and here the begening of it (DB V1.13):

feel free to say that im a genius.....cause i am one of them......
