These web pages give the opportunity to manipulate the figures of the associate paper. Some figures take time to be usuable in the applet. First page needs more time for the applet itself (2.1 Mo) On the page 9 users can make some geometric construction, by the macro-onstructions embeded in the figures. Four files, for four parts : intrinsic geometry on the main sheet, intrinsic geometry with full rolling-up, conjugation on the pseudosphere, geometry on hyperbolic pseudospherical surface. All constructions are made with CaRMetal. |
