I used a piece of software called 3D Studio MAX but there are other options like Maya, even some open source projects like Blender 3D. The learning curve for these programs can be somewhat steep but there are plenty of internet tutorials around.
Sorry for delayed reply. I had a look if I still had the rendered filed and it seems I deleted them when I was having HD space issues. I still have the original modelling files so I would need to re-render and re-edit the animations. When is your presentation?
