3-D

Hi. I'm trying out some more 3d stuff. i've got the perspective
correction fuigred out (i think). I need to know how to find the normal
of a polygon, to see if it is facing the view point so it will only draw
the polygons if they are visable. Each polygon can have any number of
verticies. each vertex is in the form: { X , Y , Z }. It needs to be
able to work out the normal for any number of points because the map
will be drawn with 4 or (possably more) sided polys and the models will
be drawn from triangles. If i'm lucky i might beable to throw in texture
mapping :)

hope you can help, i dont have a clue on how to work that out!

If i can get some of this working, i could perhaps make some interesting
VR game or scene or what ever, i have quite a few other ideas for
controlling other aspects of a 3D scene.
