Subject: Quicktime 10:39 4/2/92 Quicktime might be overkill for this purpose, since even the best MPEG compression algorithm will not do as well as one which can recreate the images from a connection table with coordinates. More importantly, reducing the animation to a Quicktime movie eliminates the possibility of interactive exploration, for example, viewing the movie from a different angle. Quicktime is slick, and would allow the movies to be used in interesting ways, but I don't think it's right as a distribution medium. At the risk of making a commercial plug, I will note that our Chem3D Viewer is freely distributable. A Chem3D owner can create a single-frame model or a movie containing any number of molecules and give it to a colleague with a copy of Chem3D Viewer, and the colleague can view the structure(s) from any angle. Moving ever closer to that oh-so-fine-line, for those still interested in Quicktime, I note that it would be a natural direction for future enhancement of Chem3D to support the creation of Quicktime movies.
