Keyboard short cuts do work, but only when the camera window has keyboard focus. It may be possible to have the panels take keyboard input in the future, just like the sgi version. There is currently no interface element that allows replacement of objects. If there were to be one, it would most likely take the form of a pull-down option menu on the "Open File" panel. As for the "failing to allocate colors" problem, this bug is described in the README-beta, included with the distribution: > Geomview uses the shared colormap rather than a private colormap. The result > is that it sometimes cannot allocate the colors it wants which makes scene > renderings look strange. Usually you can work around this by killing off > other colormap hungry applications before starting geomview. The shared colormap is usually (and expected by Geomview to be) 8 bits. On the SGI, this 8 bit colormap is often more heavily used by applications than on other machines. 4Dwm (the sgi window manager) alone seems to take up over 40 color cells(!) out of the 256 available. Geomview requires at least 216 (6x6x6) free cells to work with (plus several for the user interface). On the other hand, if Geomview used a private colormap, whenever the camera window got focus there would be "colormap flashing". This just highlights some of the general stupidity of the X window system. Future versions of X geomview should look to see if there is a 24 bit colormap available and use that if possible. > > Apologies if you all ready know about all these errors.

The source for X geomview is on the Geometry Center file system in /u/gcg/ngrap/src/bin/geomview/x11 and the source for mib is in /u/gcg/ngrap/src/bin/mib. The mib library (which is basically a wrapper around motif) is in /u/gcg/ngrap/src/lib/mib. Hope this helps. Feel free to forward any other questions you have about the X version of Geomview to me. best wishes, Daeron daeron at geom.umn.edu
