I am going to experiment with a number of possibilities. For Squeak programming, there is actually Squeak-Alice. The point is made that "Alice is primarily a scripting and prototyping environment for 3D object behavior, not a 3D modeler". A friend encouraged me to look at Anim8tor, a free 3D modeling tool. I just had gotten AC3D, to use. I will evaluate both, to see which one works best for me. I want to use one to develop 3D models of 16th and 17th Century ships, for use in a simulator/game.
If anyone is either interested in participating in some role in this effort, please contact me at jimcbender @ gmail.com.
