Digital Domain and ILM were two of the biggest studios involved in the massive quantity of VFX shots required for Star Trek.  They sit down with CGSociety to discuss some of their work.  They start off talking about the new Enterprise and some of the problems with working from a completely CG model.

A lot of times you build a ship and dirty it down and that instantly makes it feel more real, but the Enterprise was supposed to be a new ship. We tried to build it in modules with final LOD (Level Of Detail), built some elements for hero shots, and tricked it out for when you see it up close.”

Later they get into the jump sequence, the snow fracture sequence, and later the engineering bay tube sequence.
