Before we rush off and write something, we should check freeware/shareware/retail to see if this is done already. Pauljs75 does have a good point. Probably have to write this for Mac and Pc owners to be fair about it. We will need this 1. File format of a Bryce object file. Hopefully its documented somewhere, if not we have to dope it out ourselves. Have to do this very methodically or we will get garbage. Once we have that then we can write an app that reads the object file and displays what's there in 3d and in a list. Users can pick what they want and it gets saved in the format they want. Some of these should be documented somewhere (.obj, .3ds, or .dxf).
