wel its a pain with Flash 5 (and slower) because you dont have drawing methods like you do in MX. You have no way in code to dynamically draw a line. You have to rely on shaping pre-existing or attached clips.

Lines arent too bad to do because thats your basec 0,0 to 100,100 hairline stretched between 2 points, so wireframe isnt so bad.

Anyway, for 2d to 3d conversion, you first have mapped out points in code. These are sets of 3 numbers to represent your coordinates in space. You then need to convert those numbers into 2D space so they can be placed correctly on the 2D plane which is your flash movie viewable scrren area. Doing that is just a matter of adjusting your x and y of the 3d point based on the z of that point and an arbitrary perspective value which determines the … well the perspective of the 3D scene. For that you’d use the following:

scaleratio = perspective/(perspective+orig_z);
new_x = orig_x*scaleratio;
new_y = orig_y*scaleratio;

Basically, you do that for all your points and then map out lines between them all however you want. once you got that, you can move your points around how ever you want and keep updating the new 2D points mapping out the lines between them and you got yourself some 3d.
