I worked on the povray output some time ago (january maybe) to add other t= hings than just atoms and bonds, but I left it unfinished because the Jmol= Viewer interface needs a lot of work to give access to informations on how= every element is rendered. This part must be thought with care. Maybe Miguel remembers the discussions we had at this time. Otherwise, the current version outputs only : - =22atoms=22 - =22bonds=22 (if you don't set wireframe to off) - and one of the structure (don't remember which) but you have to manually= edit the .pov: set to true a =23declare showXXX. The showBonds section is empty in the first case because of wireframe off. Nicolas |
