Thanks Peter ;)
I should have set OT in my subject and fix that 3D to 2D mistake.
I mean a cos sin formula without using Away. Like first transforming to
X and Z and then to Y if I remember right, with the newscale using fov
first...looks like that:
var newscale:Number = fov / ( fov + z );
clip.scaleX = clip.scaleY = newscale * scale;
clip.x = centreX + x * newscale;
clip.y = centreY + y * newscale;
ok maybe I was just blind.
that should do it:
var newscale:Number = fov / ( fov + z );
x2d = x*newscale;
y2d = y*newscale;
But I remember somthing a bit more complexe -> accurate maybe

I put it there just for you, also because I noticed we didn't have any
example there( for some reason).

Hey guys,
I'm looking for the simplest formula to convert 3D coordinate to
2D screen ones.
Like in Keith Peters book, I can't find my book and my old code
also. Any on can make a fast copy/past for me?
Thanks
Laurent
