Hello!

I just have released version 1.2 of the astronomical application "Die Planeten"
for Irix and Windows.

The homepage of the project is:
http://www.martin-steen.de/dieplaneten/ ... en-en.html

The main changes are:

- zooming with right mouse (important for original SGI mouse)
- Uranus ring
- Uranus- and Neptun moons
- Moon names
- Anaglyph mode ( http://www.martin-steen.de/dieplaneten/anaglyph/anaglyph-en.html )
- Version information ("about box")
- Improved textures for some planets
- JPEG-Textures instead of TGA, resulting in smaller files
- Language and planet settings are saved

For those who discover problems with missing GLUT-libraries, there is a link
to the nekoware glut package on the project homepage.

Best regards, Martin

Hi,

I just finished a little demo for Irix-machines.
It shows a spinning SGI-cube-logo using OpenGL.

http://www.martin-steen.de/sgi/3dlviewer-sgi.gz

The whole demo is compressed into a single executable file.
Just gunzip the file and start it. I have tested it on my Fuel
workstation. The picture below shows how the programm
should look like.

There are a few keys for interaction:
e - toggle environment-mapping
r - reset/toggle rotation
a - toggle anaglyph mode (red/cyan glasses required)
esc - quit
Left mousebutton + mousemove: rotate
Right mousebutton + mousemove: zoom

(3D model made with Wings3D)

Best regards, Martin

P.S.: if glut libraries are missing, install the nekoware glut package:

@nekonoko: thank you for the blog report! :-)

About the crash: there is no
crash on my own machines (fuel & octane). Strange.

@edefault:
@deBug: ok, I work on a new version where you can use your own image
and that has an improved rotation control.

@fzalfa: unfortunately, I don't know how to make a screensaver for Irix.
Maybe somefrom from the forum here knows.

As with deBug, I get no segfaults.

It runs VERY slow on my Octane1. Without environment-mapping (press e to switch off),
it runs fast, but it looks only half as nice, of course

Hello,

People were asking for more features, so I give people what they want!
Next week I am on a vacation, so I had to finish it quick.

You can download the new version here:
http://www.martin-steen.de/sgi/3dlviewer-sgi.gz

New commandline options are:

-xrot = X-axis rotation only
-yrot = Y-axis rotation only
-zrot = Z-axis rotation only
-window = Start in window-mode
-map <image.tga> = change map (see notes)
-itsacow = ???

Also, the zoom-limit has changed so you can take a very close look at
the model.

About the map-feature: You can provide your own environment-map as
a Targa-file (.tga). Size must fit the OpenGL requirements
(e.g. 256x256 or 128x128 or 64x64 Pixels), depth must be 24 bit.
I made a 256x256 Pixel test image with "gimp" on my fuel and it
worked.

Example:

Code: Select all


   3dlviewer-sgi -yrot -window -map myimage.tga

= start the demo with y-rotation in window-mode, using
"myimage.tga" for mapping.

Have fun, Martin

Wrote on the subject of Motif fileselector box is blue at June 10, 2009, 11:56 p.m...

Hello,

when I create a Motif fileselector box, it always has a blue background (see image),
but I would like to have a more common color (like grey).

System: SGI Fuel
Is that a matter of system settings or do I have to tweak the colors in my app?

The sourcecode is:

Code:

  #include <stdio.h>
  
  #include <stdlib.h>
  
  #include <Xm/FileSB.h>
  
  int  main(int argc, char* argv[])
  
  {
  
  Widget        toplevel, dialog;
  
  XtAppContext  app;
  
  char* FileBoxName = "Select File";
  
  if (argc == 2)
  
  {
  
  FileBoxName = argv[1];
  
  }
  
  XtSetLanguageProc (NULL, NULL, NULL);
  
  toplevel = XtVaAppInitialize (&app, "Fileselector",
  
  NULL, 0, &argc, argv, NULL, NULL);
  
  /* Create a simple FileSelectionDialog -- no frills */
  
  dialog = XmCreateFileSelectionDialog (toplevel, FileBoxName, NULL, 0);
  
  XtAddCallback (dialog, XmNcancelCallback, (XtCallbackProc) cancel, NULL);
  
  XtAddCallback (dialog, XmNokCallback, (XtCallbackProc) echo_file, NULL);
  
  XtManageChild (dialog);
  
  XtAppMainLoop (app);
  
  return 0;
  
  }

I think there a Motif specific across all widget classes one somewhere.
http://www.le.ac.uk/cc/dsss/docs/xcustom.shtml asserts possible to ascertain some of the resource names which can be used by referring to the documentation on the widget library. The OSF/Motif "Programmers Reference" is useful if doing this for Motif based programs.

You could also do it programatically.

Thank you for the hints and the links, I will give it a try.

I know that one can make a fileselector-box with Qt or GTK, but I don't want users to have to
install a bunch of libraries. AFAIK is Motif the "lowest common level" for Unix systems and it
works without installing additional libs (at least I hope so).

The resource and value part can be very generic or more specific. For example

- "*XmBlah*.background: white", would make every instance of XmBlah's background white.

Thank you a lot! I will try this when I'm back home this evening.

I still wonder why the default-color is "light blue". But if I can manage to change the colors with
some Motif function calls, everything is great.

That fallback-argument did the trick. It seems like only the line

"*SgNuseEnhancedFSB: TRUE" should have activated the SGI style file selector box and given you the improved box....hmmm.
Try adding this to the widget's resources:

Code:

   argcount=0;
   
   XtSetArg( arglist[argcount], SgNuseEnhancedFSB, TRUE );argcount++;
   
   XmCreateFileSelectionDialog( w, "openFileDialog", arglist, argcount );

Thank you for your help. But the additional code did not change anything.

I found the solution 10 Minutes ago on this page:
http://mecca.spd.louisville.edu/ebt-bin/nph-dweb/dynaweb/SGI_Developer/IIDsktp_IG/@ebt-link;cs=fullhtml;pt=1134?target=%25N%15_18455_START_RESTART_N%25#X

The trick is, that you have to add -lSgm to the linker-flags in the makefile.

Code:

LDFLAGS = -lSgm -lXm -lXt -lX11

Now the fileselector box looks like it should!

Wrote on the subject of Fractal benchmark at June 23, 2009, 3:51 p.m...

Hello,

here is a little program that can be used as a benchmark in a multiprocessor environment.
It calculates three beautiful (?) fractal images:

http://www.martin-steen.de/sgi/frbatch.tar.gz

It makes heavy use of posix threads, so the programs benefits a lot of systems
with more than one CPU. Actually, it is a multithreaded floating-point benchmark.

Atfer unpacking, run the script "./run1.sh" to run a fast benchmark. "./run2.sh" runs a
slower benchmark that creates bigger images. The script uses four threads,
but you can adjust the scripts to use more threads or create even larger images
(8000x8000 pixel are no problem, but it takes a while).

When the benchmark has run, another small program converts the images from Targa
format to Jpeg. The programs are compiled for 64 bit machines (-64 -mips4).

On a SGI Fuel, the first script takes about 120 seconds.

Also, on MIPS (and other properly designed architectures), 64-bit apps actually run *slower* than 32-bit ones, so compile for 64-bit only if your app uses more than 2GB of memory.

That would be great! I can also give you the sourcecode so you can compile your own

Hello Joerg, hello ShadeOfBlue, hello Geoman,

if you dare to run the app on your multiprozessor machines, here is the sourcecode for the
fractal batch programm:
http://www.martin-steen.de/sgi/fractbatch-source.tar.gz

Just type "make" to build the executable.
Run ./testrun.sh to create three (simple) fractals

This test is not a real challange for a machine with 16 cpus.
To make it more interesting, you can try:

Code: Select all


   ./fractbatch 8192 8192 1024 32 frects0089.txt

This creates the three images with a size of 8192x8192 pixels
and uses 32 threads.

Remarks:
- The limit for Targa pictures is 32768x32768 Pixels.
- maybe you know compiler switches for a faster executable

Martin

The other command uses about 10-12 CPUs and is still running

When it finishes, I will try to get the first test to run on all CPUs (will probably require setting the number of threads to 64 or somesuch).

Thank you for starting your huge machine for this test!

It looks like IRIX does not start all CPUs when a thread is running to short.

After starting, every worker-thread calculates exactly four lines. The supervisor-thread
waits for all worker threads to stop (*) . Then the supervisor-thread writes the lines to the
TGA-file and starts the threads again to compute the next four lines.

This process makes it possible to render pictures of nearly arbitrary size (without consuming
much RAM).

Quote:

The program dumps core at 40+ threads

Probably this has something to do with the number of lines. Maybe the picture is to small for
so many threads. I will check the source.

Thank you for your report!

Best regards,
Martin

*) The worker-thread does't really stop, but waits (pthread_cond_wait) for the next start signal

Martin, this program is phenomenal. Fullscreen with the Earth blown up big it's my new screensaver.

For the next version, could you make the information and control windows separable ? If it were just the planet on a black background it would be absolutely perfect. Maybe make the background even blacker, if that's possible.

I could sit and watch this thing for hours .. but where's the ice caps ? You could drive a freighter from Shanghai to New York over the north pole right now ...

thank you, a lot

Thank you hamei! :-)

You are right, the earth looks different from space. That's why I'm going to replace the earth-map with the "blue marble"-texture.

BTW: there are indeed plans to route ships from Europa to Asia via the so called "Northwest passage".

I re-create a 1680x1050_60. celestia, blender and die-planeten run, but I have a lot of artfacts and stanges colors.
I'll try the cube

Weird. I must confess that I don't have a clue.
When you press the "e"-key while running the cube-demo,
does that change anything?
("e" switches environment texture mapping)

Maybe one of the expert here has an idea.

Vulcan death grip failed, power button failed, I had to pull its life support cord. Sumbitch.

Got it back running again, since Mom is a Republican I guess stupidity is inherited. I gave it another try, this time from a terminal. Wham ! locked up instantly again. I was hoping that just that app would freeze and I could close the terminal window but no such luck. Same thing, nothing did nothin', had to cut off her vital bodily fluids to shut down. Damn commies are everywhere.

This is an r5k-350 O2 running 6.5.22, graphics is 1440 x 900, neko glut (the latest one, forget what rev.)

I'm very sorry to hear that! (although your description made me laugh, sorry again!)

It seems like there is still lots of work to do.
Hope I get the Octane 1 running, so there is a
second system for testing.

Thank you and thanks to nuts and all other users for testing and for the reports, I will update this thread
when there is a new version.

Best regards,
Martin

Same lockup here with another O2 r5k-350. Tried two different default visuals because it's working fine on my O2 R12k-400. While one did show me a false-color window frame of Die Planeten and the other showed nothing at all, both resulted in a lock up.

Martin, could you please link the next version with "-rpath /usr/nekoware/lib" (or "-Wl,-rpath -Wl,/usr/nekoware/lib" depending on how you invoke the linker)?

Could you do a test with a demo program?
Here is the sourcecode:
http://www.martin-steen.de/sgi/chromawa ... rce.tar.gz
It contains a simple makefile. This program is much smaller than "Die Planeten".

(Below is a screenshot of the chromawave demo)

Best regards, Martin

Hello,

here is another little interactive OpenGL demo.
http://www.sgi.faktor0.de/chromawaves.tar.gz

Hit the space bar to create colorfull waves.
Move and zoom the field with the mouse.

Sourcecode with makefile for MipsPro-Compiler:
http://www.sgi.faktor0.de/chromawaves-source.tar.gz

This demo has more error-checking code than my other
programs, but, als always, start at your own risk .

Required libraries: GLUT library

I wonder if you could reverse the action of the scroll button ? It's backwards from the way zoom works on any other apps I have ...

You know what would be useless but neat ? Pipe the output from sound to act as input. i always liked that rotating drum equalizer demo thing. This is even spiffier.

thank you.

Thank you for testing, hamei!
I take your tipps and suggestions into consideration.

Best regards,
Martin

P.S. I had to look up in an dictionary if "spiffier" means good or
bad, but I learned it means good

Right, that's why SGI recalled the RM7K/350MHz CPUs. Kind of interesting to see it pop up now though, and equally interesting that the faster RM7Ks aren't affected.

Edit: A little more info here: http://groups.google.com/group/comp.sys ... fecdf3e025

Looks like it was a RM7000A problem. The 600MHz hobbyist upgrades use the RM7000C.

Both apps (Die Planeten, Chromawaves) make heavy use of trigonometric functions like sin() and cos().
I have sent hamei a test version of the demo program to proof it's not a software glitch. I' m still not sure
if it's a hardware bug. 99.999% of all bugs are software related (that's my experience, at least).

Best regards,
Martin

P.S. thank you very much for reporting about my programs on the start page!

I'm just curious...

Is the O2 not a 64-bit-machine?
It's 10 years ago that I worked on a O2.

Here is another executable for you, compiled with compiler-switches -n32 -mips3:

Just tested it on the Onyx2 IR2E and the Onyx IP, works great on both. Just a note : it looks a bit dark (eg. I don't see anything until I hit space), I'm not sure if it's related to my gamma settings (I use gamma 1.0 on my sgis)...

Run "./chromawaves -auto" if you want the see waves from the beginning.

It has a 32-bit kernel, since there's really no reason to run it in 64-bit mode due to the 1GB memory limit (it can, however, still use 64-bit instructions -- it just lacks the kernel support and libraries that use a 64-bit address space).

It is more efficient to run MIPS4 N32 code on all SGI machines that have an R5k or better CPU inside (and MIPS3 N32 for R4k). Compile it as 64-bit only if your app uses more than 2GB of memory, otherwise it will just cause a slow down and use more memory.

So the O2 has a 64-bit CPU, but it cannot run 64-bit code because the kernel and the libraries are
32-bit? That's good to know, if one is going to use posix memory mapping (mmap) with big files.
(on my job I have to deal with satellite images that can be 200GB large).
