[NB: Scott Anderson supervised the visual effects of Starship Troopers for Paul Verhoeven, and many facilities participated, including Sony Imageworks, ILM, Tippet and MASS ILLUSIONS. The pictures below are just to illustrate the movie and, in a few cases the types of elements involved, e.g. thrusters. I have no idea who did these particular shots, with the possible exception of the one of the escape pod, which was probably done at MASS ILLUSION. People are very touchy about their credits and who can blame them?]
I started laughing. I hardly ever read shaders with Latin abbreviations, in fact it had never happened before. NB, of course, is Latin for "Nota Bene" or "note well", its a convention used by mathematicians of the old school and classical scholars of all types. It basically means "pay attention". Its the sort of thing one would expect to find when reading a scholarly treatise about St. Augustine's City of God (de Civitate Dei) or perhaps the notes of a 17th century alchemist. Or a mathematical proof.
