A new Mofif version 2.5.2 was released April 17, 2026: https://github.com/thentenaar/motif This new version seems to cause some problems with Geomview built with it. In particular there is file name mangling. If I attempt to open a file from the Geomview dialog, the file name that is entered is mangled causing the file load to fail. A workaround would be to enter the file name as an option on the Geomview command line: geomview file.off & There may be other issues but I have only noticed the file name mangling problem. This problem does not occur with the previous Motif version 2.3.8. The new Motif 2.5.2 introduces changes that are causing problems for other software as well. |

Hello, I've been improving the interface of Maxima (https://maxima.sourceforge.io) to Geomview. The Maxima command: plot3d (1/theta, [theta,0,%pi], [phi,0,2*%pi], spherical, [palette,rainbow], geomview) Produces the plot in https://maxima.st/plots/img/cup.png Now I will introduce 2d plots (currently we can only use Geomview with plot3d and not plot2d). Regards, Jaime |

For my long term objective (factoring a RSA number bigger than RSA-250, which took 2700 CPU core years) https://stamm-wilbrandt.de/en/#long-term_objective I needed to view 3D polyhedron of points n=x²+y²+z² with n=pq semiprime and p,q both =1 (mod 4). First I used jscad.app for that, but for bigger n I wanted to use qhull and geomview. From my old planar_graph_playground repo I took planar graph 6-coloring, determination of dual graph and then colored the polyhedron faces with at most 6 colors. Since both face colors for an edge are distinct, I made geomview not display edges. Now for much bigger n I can view at the polyhedron. All 6-coloring qhull work and screenshots can be found here: https://github.com/Hermann-SW/RSA_numbers_factored/tree/main/qhull Besides display of 6-colored polyhedron, statistical output is generated as well: $ ./pq6col 13 277 n=3601: 480 vertices, 1128 edges, 650 faces (6 colors) face lengths 408×3 210×4 32×6 Regards, Hermann Stamm Wilbrandt. |

I have recovered a version of the StageTools website of 2006 from the Wayback machine archive, and I published a mirror in one of my websites: https://maxima.st/StageTools/welcome.html You can find the 2006 version of the code there.

Re stagetools, the Geometry Center archive for it is still alive: http://www.geom.uiuc.edu/software/download/StageTools.html <http://www.geom.uiuc.edu/software/download/StageTools.html> But this version is dated from August of 1998. I don't know whether Davide Cervone had released a later version elsewhere.

Davide Cervone did release a new StageTools in 2006 that does work with the latest Tk/Tcl. This is the version which I am using. However, after acquiring that 2006 version I have not been able to find a current link for it. I have the 2006 source code and would be glad to upload it so that Geomview users can benefit from it.

The StageTools links are working now. I say "temporary" because I had to append the ".txt" suffix to each StageTools script file. The StageTools script is not a valid MIME type and this may be the cause of the 403 error. Whatever the case, just remove the ".txt" suffix from the file before loading into StageTools. Also, the source code for StageTools module seems to have dropped off the web. None of the links is active. If needed, I can provide a copy of StageTools. Just let me know. Eventually, I hope to post the StageTools code on GitLab. |

Hello, Very nice example. However, the "Link for StageTools Script" at http://lapiet.info/mathphys/diffgeo/diffgeo1/geomview/monkey_Saddle-parabola-curve.cs is not working. I gives me the following error message: Forbidden You don't have permission to access this resource. Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request. Regards, Jaime |

For those who may be interested, I have used Geomview, in conjunction with the StageTools module, to create visualizations of basic differential geometry concepts, including videos. I plan plan on more of the same in the near future. The web page is located here: http://lapiet.info/mathphys/diffgeo/diffgeo1/monkey_saddle.html Geomview does not perform anti-aliasing but the GNU/Linux Nvidia diver has anti-aliasing capabilities which have smoothed the Geomview graphics. Geomview/StageTools/Nvidia is a great combination for rapid and effective graphics/videos. |

For those who may be interested, I have used Geomview, in conjunction with the StageTools module, to create both graphics and videos that depict various differential geometry concepts. The web page is located here: http://lapiet.info/mathphys/diffgeo/diffgeo1/monkey_saddle.html There will be other pages to follow in time. Geomview/StageTools is perhaps underutized for its utility in visualizing advanced mathematical concepts. |

After creating a directory "/opt/motif/include" I temporarily moved all my Mofif /usr/include/Xm files to this directory. As predicted, the command "./configure" fails to find include/Xm but the command "./configure --with-motif=/opt/motif" will succeed.

I notice you are missing a '-' in your configure command, the option should be '--with-motif'. If this isn't the issue (you used '--with-motif' in a previous message) then look at the config.log file. It will say what tests were run to check the user install of opemmotif, and will include any error messages that resulted.

Thanks for the starting hint, Larry.
geomview's configure error message was minimally informative:
% ./configure
[..]
checking for Xmu... yes
checking for motif... configure: error:
Can't find Motif header file Xm/Xm.h. Geomview requires Motif
(or Lesstif). See the file INSTALL.Geomview for details
geomview-1.9.5 % ./configure -with-motif=/opt/homebrew/opt/openmotif CFLAGS="-I/opt/homebrew/opt/openmotif/include"
seems quite specific, but produces the same error. as does include/Xm.
The ssegfaulting homebrew package I want to compare this build against just does a simple configre and make, per their rules:
"Our install block isn't very complex:
def install
# Work around for build error due to `finite`/`isfinite` detection on macOS.
# ../../../../include/porting.h:68:19: error: expected identifier or '('
# static inline int finite(double v)
ENV["ac_cv_func_finite"] = "yes" if OS.mac? && Hardware::CPU.arm?
system "./configure", *std_configure_args, "--disable-silent-rules"
system "make", "install"
(bin/"hvectext").unlink
end"
https://github.com/Homebrew/homebrew-core/blob/3cfdadd1bba50f0c3fa7e717f3a6bdff72c859db/Formula/g/geomview.rb
so I wonder how they ever built with openmotif. That ruby std_configure_args hides a lot of sins.
https://formulae.brew.sh/formula/geomview
shows that every recent homebrew install of Geomview has failed.

That should not make a difference. Even though the motif headers
are located in the /Xm subdirectory the Geomview source files contain,
e.g.:
#include <Xm/AtomMgr.h>
The angle brackets tell gcc to prepend a standard search path, usually
/usr/include/, to the Xm/AtomMgr.h.

You may then need to add to your CFLAGS variable something like
this:
CFLAGS = "... -I/parent/include"
This will inform gcc to add "/parent/include" to the standard search
path and thus a file directive like "#include <Xm/AtomMgr.h>"
will translate to "/parent/include/Xm/AtomMgr.h"
It could also be helpful to post the exact error message indicating
the files referenced.

okay, the Mac homebrew maintainers have said 'our geomview package is crashing? who uses it anyway? not our problem, talk to upstream' so I'm attempting to figure out said crash by compiling my own copy of Geomview 1.9.5 on an overpowered Macbook that I really don't know how to use. I so far have figured out that this particular paragraph of configuration advice in INSTALL.Geomview is Not Helpful Or Accurate: --with-motif=DIR You can use this option if the Motif header files and libraries on your system are installed in some place that your compiler doesn't recognize by default. This option specifies that Motif is installed on your system in the directory DIR. DIR should have a subdirectory called `include' which has the Motif header files, and a subdirectory called `lib' which has the library files in it. You don't need this option if your compiler can find the Motif header files and libraries in the standard places that it looks. If you're not sure about this option, try configuring without it. 'configure' will abort with an error if your compiler can't find the appropriate header files and libraries. Openmotif is the opensource motif of choice these days (here, 2.8.3_3) and its directory layout is different and does not match the description above. include does not have the Motif header files, but include/Xm does, as shown by the output below. I suspect that this new directory layout may well hold for more than just homebrew, or the Mac. So, how do I force configure to recognise the extra Xm subdirectory which contains the Motif header files, and thus recognise that openmotif is acting as Motif/lesstif/whatever? ./configure --with-motif=/opt/homebrew/opt/openmotif does not do what is wanted, because of the extra Xm subdirectory, and copying all the include headers up a level from include/Xm to include/ does not seem desirable. Geomview configure would seem to need some sort of update to check in extra subdirs. I also suspect that this INSTALL.Geomview text also needs to be updated to reflect this modern reality. Thanks in advance for any and all advice.

Murray, geomview exists as a homebrew package. homebrew is probably slightly ahead of macports these days. https://formulae.brew.sh/formula/geomview See https://brew.sh on how to install homebrew, then brew install geomview will install geomview and all its dependencies successfully. I've just done that. log at end. Installation successful, your question answered! However, actually *running* the homebrew geomview repeatedly and consistently causes geomview to segfault and dump core on the M4 Macbook Pro I just tried this on. Your mileage may vary. lloyd@192-168-1-104 savi-dev % geomview & [1] 27339 lloyd@192-168-1-104 savi-dev % \Geomview(27339): internal error: "Segmentation violation"; dump core now (y/n) [n] ? got

How can I install geomview-1.9.5 under macOS Sequoia I tried MacPorts, but building geomview with it fails (see https://trac.macports.org/ticket/69420 ).

However, using the latest autoconf/automake on the github version gives many warnings: Makefile.am:1: warning: 'INCLUDES' is the old name for 'AM_CPPFLAGS' (or '*_CPPFLAGS') These are just warnings and not errors but someone may want to have a look at the Makefile.am files in the github source tree to possibly bring them up to date. Also, geomview has no built in anti-aliasing. A nice workaround to this, if one is using GNU/Linux Nvidia graphics, is to enable FXAA (fast approximate anti-aliasing) using the "nvidia-settings" utility before using geomview. Anyway, I look forward to the next 11 years of geomview use. LAP |

Okay the variable typo that has been staring me in the face has been
pointed out to me. Thanks, Fred!
(The sphere shade is still slightly different from what is set,
but it's no longer THAT different.)

I'm experimenting with changing the color of an existing sphere drawn in the camera window in OpenGL. No texturemapping, just a
blank sphere.
I rewrite and replace the sphere definition from Tcl in SaVi with e.g.:
geomview(puts) "(read geometry { define unit_sphere_h {
appearance {shading smooth material {diffuse $geomr $geomg $geomg} }
SPHERE 1.0
0.0 0.0 0.0
} } )"
(put in \ for Tcl linebreaks, or run it into one line, it doesn't matter)
where $geomr $geomg $geomg are the R/G/B color values in a range 0 to 1.
Those are computed from a value provided from hex value provided from a Tcl color picker which gets sliced and diced into the right 0.0 to 1.0 (three times) format.
For bright colors, it's fine, the color drawn by Geomview on the sphere is at least vaguely recognisable, though the shade always seems a little off.
As you choose darker and darker shades, or a predominance of R, G or B over the other two, the sphere in Geomview's camera just turns a slate gray and is increasingly off the RGB colour selected.
but if you similarly select the backcolor with:
geomview(puts) "(backcolor focus $geomr $geomg $geomb)"
that's just fine and dandy across the spectrum, just redraws in the chosen dumb RGB color.
To illustrate this, the attached screenshot shows the sphere and backcolor set to the exact same RGB shade of blue.
Any idea what's special about sphere/object colors? Is there some sort of linearity adjustment? Or is this related to a lot of color theory or object reflectance and rendering that I simply haven't read, which would explain why SaVi's 'blue" default sphere is
RGB values 0.2 0.4 1 ?
Any why doesn't texturemapping play by the same rules? An RGB value in a texturemap shows up mapped to a sphere in the right shade as I'd naively expect.
thanks for any pointers,
Lloyd Wood
