Actually, the path is not exactly helical, it is a FLAT spiral. Allow me to elaborate. I'm building a 3D walk around system in windows. I plan to generate a LOT of frames (a few hundred), and show the appropriate frames as the user moves through the space. The space is a cylinder, and users will move about it using cylindrical coordinates. That is, they will control their height within the cylinder, their distance from the center, and their direction ( angle away from "north"). For simplicity sake, the user is always facing out from the center (Obviously, there are actually two paths, one for the camera, and one for the target, but they are almost identical). Currently, the cylinder has about 30 cameras in it, and each camera sweeps out a flat spiral path. It is critical that that each of the camera paths be flat. Each camera path differs from the others only in the Y coordinates of each of the keys. Obviously, this is a rather cumbersom solution. I would like to use 1 camera to achieve what the 30 are doing now, so I need to somehow combine the paths of the existing cameras into one path. Unfortunatly, I don't see how I can do that in the context of 3D studio. Thanks, MikeA
