I just want to ask if you have a recommendations regarding to Computer Simulation workspace assembly.
I want to make a software just like these, but the problem is that I don’t know how to start. What package/library do I need to make a software like that using Java programming?
There are a few tools to create those videos, like 3D Studio in http://usa.autodesk.com/3ds-max/
Also there are video tools for post-production video like Adobe Premiere and a few other free tools.
You really should forget programming to do that… unless you want to be a 3D programmer. If you don’t even know what Java or other can do, just forget it. Use existing tools to do that.
Good luck.
