Star Trek is IDEAL for modeling projects in Carrara, given the geometry of the spaceships in the various series. The mechanical but flowing lines of the Federation ships such as the Enterprise, Reliant, Grissom, the Klingon D7 and Bird of Prey, and others, with very few greeblies, are an enjoyable contrast to the greeblie-encrusted starships of the Star Wars movies. Additionally, the sheer beauty of their designs, from an aesthetic point of view, is breathtaking. The "drydock" scene in "Star Trek: The Motion Picture" where Scotty takes Captain Kirk to see the newly-refitted USS Enterprise is to this day my all-time favorite special-effects sequence in any movie, ever. (Even beating out the Star Destroyer chasing the Rebel Blockade-Runner scene at the opening of Star Wars: Episode IV, which is my second all-time favorte SFX scene.)
After doing the tutorial in Ray Dream Studio 4.0, back when it was made by Fractal Designs (then MetaCreations, then Eovia, and now Daz3D) was the refit USS Enterprise. It took me many weekends to even get the basics shapes down, but thanks to how easy RDS was to learn, most of my time was actually spent just enjoying the software itself, not struggling to learn it or to get it to do what I wanted it to do. The rest of my time was spent in Adobe PhotoShop (v4, if that gives you any idea how long ago this was) making my first very crude texture-maps.
Unfortunately, this was back in the day when the only "reference" materials that I had were my own memory of the ship, plus a well-worn VHS copy of ST: TMP and "Wrath of Khan." So I got a lot of it wrong, and the texture maps really were pretty primitive, but for my very first project, it turned out rather well. Over the years, however, I've been slowly refining it as newer versions of Ray Dream and then Carrara were released. Recently, I've made quite a few upgrades to the Enterprise NCC-1701 model, and that prompted a "refit" of this gallery as well.
