I have been using Bryce for 24 hours. What I want to do, very badly, is render dirigibles. I have this thing for dirigibles, and I want to make some illustrations of dirigibles in weird settings. So as soon as I understood how objects worked, I tried to figure out how to make dirigibles. While Boolean objects are very powerful, I get the feeling Bryce is not the greatest tool in the world for 3D objects. You got the primitives, which can be combined in various ways, and some simple transformations, and that seems to be it. What I need to be able to do is render a long cigar-shaped solid which is sort of faceted longitudinally (representing the longitudinal ribs of rigid airships such as zeppelins). I used to work with computer graphics back in the eighties, and from what I did then I thought what I needed was some kind of extrude tool. I could draw a line representing the curve of the hull of the dirigible, then extrude it into a long thin plane. Then you duplicate and rotate the plane around an axis representing the longitudinal axis of the airship. But Bryce has no extrude tool. However, Bryce does make it easy to move the origin point out away from an object so you can do the duplicate and rotate trick. Now all I needed was a way to get the initial primitive to dupe and rotate. Someone on Usenet suggested there were better 3D modeling applications out there, which I might use to build the dirigible and import it into Bryce. In the end, I have worked out something with terrains, but it's not perfect. If anyone would like to help, I've put it all down in an illustrated journal at: http://www.employees.org/~redneck/graphics/journal_01.htm Thanks, Mitch Barrie
