Greeting Joanna_JL,
we are sorry if we caused any kind of confusion. Fibix is devided mainly into 2 parts. Fibix Framework(Engine) which can be used as engine(core component) for other applications and Fibix Editor, tool used for real-time rendering.
If you have any other questions feel free to ask.
Here is example of presentation you could create with fibix editor(note that I am not talking about models but materials, lights, video recording and ofcoarse rendering.)

Thanks for your support,
Fibix Team
