How can I balance my love for physics (esp. astrophysics), animation and computer engineering?

I am a student of Computer Engineering and while I am quite happy about the field, I am deeply fascinated by Physics, especially Astrophysics. Similarly I have a strong interest in Animation. I am not sure how I can have all these three fields in my professional life. I wish to do serious work in all three fields. How do I go about it? Any ideas, advice, inspiration, taunts are welcome.
