I think the best we can do with geomview right out of the box, assuming the user specifies no information, is arrange for it to work from its own directory. If you want to install it elsewhere you can edit the "geomview" shell script; only one line has to be changed and there are comments at the top of the file telling you what to do. After changing the relevant line in "geomview" to indicate the absolute pathname of the geomview directory, you can run it from anywhere. The new README file, which I finished updating after you got gv0.tar.Z, explains this. The README you have is the old one. > There is one really annoying feature in the istropic geometry switch in > gv1.3, and that is when you switch geometry the particular view of the > world that took 20 minutes to get just right, is destroyed and the default > values are reinserted. > > It would be much nicer to leave resetting to the reset button and just > switch the geometry, like when you change the lighting, it doesn't change > the window, the position, etc. The problem is that quite freqently the view settings don't make sense in the space you switch to. The matrices describing the positions of the geoms and cameras must be isometries (or similarities in Euclidean space); switching spaces would break this unless they're all reset to the identity, or to some space-specific default values. To get reasonable behavior close to what you want I think we'd have to store a separate matrix for each space for each geom and camera, which seems a bit excessive. Plus, more to the point, why are you switching back and forth between spaces with one data set anyway?

Try selecting "world" in the object browser and then click on the new "Look" button in the tools panel. It arranges for the camera to look at the selected object. --Mark
