The problem is that ptcl does not contain any layout information of the stars in a system, so viewing the ptcl system visually is hard. It would be nice if we could have Ptolemy try to layout a visual representation of the ptcl graph, but that functionality is not present in Ptolemy Classic. I believe the Diva package, which is used by Ptolemy II, will attempt to layout a graph, but it would be a big project to integrate the two. Tycho has some hacks in it that will display a ptcl file as a tree, but these hacks are not well supported. I believe that if you start up tycho outside of Ptolemy, and try to open an oct facet, then oct2ptcl is run and some sort of graph is displayed. This is probably not of that much use to you. To run a galaxy that contained some ptcl code, you could try creating a galaxy that contained a TclScript start, where the script either contained your ptcl code directly, or sourced a file that contained your ptcl code. I'm not sure if this would work, but it is where I would start. -Christopher -------- I just started using ptcl (on RedHat Linux 5.1). Is there any way to look at the a visual representation of the galaxy I'm creating from the ptcl console (or tycho) window? I'd like to use ptcl to create a galaxy that would then be placed in user.pal as an icon where I can use it again and again. Am I missing something obvious or is this not possible?
