I was thinking of making models that basically morph one 2D shape into another 2D shape through the 3rd dimension. Basically if I was morphing a triangle into a hexagon while working up a column each point of the triangle would split into 2 points to help create the hexagon on the opposite end. How might someone accomplish this with a circle since there would actually be no points to work with?

like this?

You can download OpenScad here ---> http://www.openscad.org/ 

It is absolutely free. I added the file that I used to make this shape below.

Yes, pretty much like this. Except not hollow through the middle and I'd consider making things more complicated than geometric shapes eventually. Maybe at one end Bruce Wayne's face, and batman at the other. lol.

This being the case, it would be rather easy to morph (lofting or skinning, as it's called in the modelling world) between shapes.  Blender, Hexagon, Wings3d, and I think even Rhino do this.  Wings3d and Blender are free options to use.  Not sure if Sketchup does this.
