Marble - Desktop Globe

Education Apps by tackat 73 comments

Not easily. We are currently using a global quad-tile set as described in

http://www.kdedevelopers.org/node/3269
http://www.kdedevelopers.org/node/3272
http://www.kdedevelopers.org/node/3275

so from that it might be possible for you to create a map theme that would display the contents of your tiffs.

The only other option would be to wait or provide patches so that Marble supports the KML feature to add images to the globe (which hopefully will be the case soon). - Sep 15 2008

My question was not "What would you need that for".

But it was "What would you need to have for that (in order to work well for you)? just a Url?"

Of course I see your motivation why you want to have the feature. And we'd be interested in providing it for you. However you need to tell us how you'd like it to work in detail. - Sep 03 2008

What would you need to have for that? just a Url? And would a setting in an .rc file be enough to solve your problem? (I only can imagine this to be interesting for people deploying Marble). - Aug 28 2008

Marble doesn't find its library.
I guess you installed Marble into /usr/local. So you need to tell the dynamic linker where to find it. This can be done by setting the environment variable LD_LIBRARY_PATH to the correct library:

export LD_LIBRARY_PATH=$LD_LIBRARYPATH:/usr/local/lib

You can also add this line to your .bashrc to ensure that it will also be found in the future.

Also please check that no previous Marble version is still installed.

This should already fix the problem.

An alternative way to fix the problem would be to set the CMAKE_INSTALL_PREFIX to /usr:
Just use

cmake -DQTONLY=ON -DCMAKE_INSTALL_PREFIX=/usr ../marble

instead of the other cmake command.

Please tell us whether this advice fixed the problem for you and which steps you had to perform to resolve it.

The problem with WMS servers is on one hand that they don't scale very well. On the other hand we want the maps to be very well integrated with the interface (instead of browsing content via a list of WMS server addresses).

That being said we'd be very interested in patches to enable WMS support for our next MARBLE release. Especially with the last changes for OpenStreetMap integration it shouldn't be too difficult to add WMS support to MARBLE. However our development resources are limited. So if someone volunteers to work on it we'd provide help to get up to speed (just visit us on IRC, freenode on channel #kde-edu. - Aug 16 2008

Ah, ok I guess it's due to Marble usually being built as part of KDE-EDU. Usually for a KDE build we'd expect that people check out all of KDE-Edu and build according to KDE4 build instructions. This release is mostly about the Qt version. See

http://edu.kde.org/marble/obtain.php

We'll try to fix the issue though. - Aug 29 2007

Yes, that must be a build problem indeed. It doesn't happen when built from source or with other packages. - Aug 27 2007

Education Apps by tackat 73 comments

Hi,

packages are being worked upon. Today the debian packager has uploaded the first package to Debian unstable. However there are still issues with it which we are sorting out at the moment. Also work is going on on providing packages for the other plattforms. I'll link the binary packages once issues have been sorted out ( I estimate about 2-3 days at most ). - Aug 21 2007

Thanks for your feedback.

The city names are from www.world-gazetteer.com. I know that although they were written in Unicode there are issues with letters for some east european countries due to the fact that under windows where this data set was compiled these characters don't exist, e.g. Romanian where s and t lack the accent (e.g. "Braşov" ).

> 2) A useful feature would be

Yes, that would be nice. I already had that idea and wasn't sure whether Qt had this implemented already. It seems I'll have to implement it myself.

At a certain point of zooming up these bitmaps will be replaced by SVG's. That's still on my TODO however.

You need to install the cmake package. Then extract the marble sources, so that you get a directory ~/marble in which the src dir is located (should be the case by simply extracting the source tarball into the homedirectory
Then do:

mkdir marble_build
cd marble_build cmake -DQTONLY=ON -DCMAKE_INSTALL_PREFIX=/usr ~/marble
make
sudo make install

After that you can start Marble either from the menu or from the konsole by entering the command "marble". - Apr 01 2007

Just a wild guess: From the error message I could imagine that eventually it's an endianess issue.
So please try commenting out marble/src/pntmap.cpp line 75-137 and line 180-183. If there should arise further questions, please mail me in private ( tackat@kde.org ). - Mar 27 2007

That's right. Just remove the -msse and -O2 compile options there to build it successfully. I'll try to find a "cleaner" solution for the next release to have optional SSE support. - Mar 26 2007

That's pretty hard to do. It really depends on your processor (Intel seems to be better there for whatever reason) and the 2D (not 3D) performance of your graphics card. Right now it should perform a lot better than pure Mesa without DRI enabled.
I will try to improve performance further (also by providing a slider which will gradually improve speed at expense of the display quality). I also plan to add an optional OpenGL backend later. However that doesn't have high priority right now.

> Other than these, the vertical
> distance measurement didnt seem

I just verified it and I don't see an error. The measure results look very much correct to me. If I measure e.g. the distance between Flensburg (Germany) and Tunis I get almost exactly 2000 km on Marble. This seems to be correct as other virtual globes show the very same distance down to the kilometer.

If you still think there's an error please send me your example measurement to tackat@kde.org. - Mar 24 2007

> more options ;)

Those things are on my Todo list already. So be patient, as I want to implement it the right way (tm ;-). Concerning the options: Yes, there will be the possibility to turn layers off. But I want to do it in a non-obtrusive way (as part of the legend actually) to provide good usability.

> Also, jpeg artifacts get pretty bad

Yes, this is the initial offline database. Satellite View and Night View are currently just provided as a proof of concept. The primary map is the topographic map.
Next on my TODO is however the capability to download further tiles.
So then the Satellite view should a much higher resolution (comparable to Nasa World Wind).
Concerning Virtual Earth: I will have a look at the way they store their tiles. - Mar 24 2007

That doesn't look like a problem of the software. That looks like you grabbed the packages for the wrong plattform. Are you trying to run it on a x86_64 maybe? - Mar 23 2007

Education Apps by tackat 73 comments

E.g. here:

http://developer.kde.org/~tackat/marble/kubuntu/marble_0.3-1.tar.gz

Or you can build directly from SVN: You need Qt 4.2, subversion ("svn") and cmake installed. Then do:

cd ~
svn co svn://anonsvn.kde.org/home/kde/trunk/playground/base/marble
mkdir marble_build
cd marble_build
cmake -DQTONLY=ON -DCMAKE_INSTALL_PREFIX=/usr ~/marble
make
sudo make install

and launch it via "marble" from the command line or from the menu.

Full Icon Themes by everaldo 385 comments

The idea is to have Crystal as a future KDE default iconset.

We are working on it :-)

And yes, I created some SuSE icons in that style already.

Yeah, the desktop icon is still a big problem. I already made a modified version which looks quite slick at 144x144 but I'm still not satisfied with it at small sizes.
We are working on this problem.

Wallpaper Other by alois-kde 14 comments

> "i think the looks of KDE

> to be impressive. first impression

It not only needs to be impressive but also usable. Your current proposal
looks indeed quite beautiful. Still there are some issues which I'd like to
see fixed.

The default wallpaper not only needs to look good - we usually want the user
to keep it as the wallpaper he uses all the time. The problem with your
wallpaper is that the contrast is to high.
You have some "black stripes" in it and some clean white parts. I would
suggest to choose dark blue for the border of the planes instead of black
and dimming down the white parts a bit.
The clouds in the background remind me of windows. You might want to fix
that if you want to avoid bitching.

Great work though. Did you do it completely yourself or did you use stuff
which was created by other people.

You might want to talk to ante about the license ... he's the kde-artwork
license man ;-)

> is what counts. it's time
> to choose some REALLY GOOD

Seems your caps-lock is broken ;-)

> say this because these wallapers
> were love at first sight.

Well, default_blue was love at first sight, too (that's the default
wallpaper right now) ...

It doesn't show any reallife objects (which makes it a pretty usable
wallpaper, it's small in terms of memory and it's still decent beautiful.

> icon set is tougher decision because i still have not seen a truly
COMPLETE
> icon set apart from the default.

Well, you don't only need to have a complete set you also need to have
people who continously take care of the iconset (that's one of the tougher
points - most people loose interest after 3 months or so ...).

Everaldo and me have been paid by Conectiva and SuSE to work on a vectorized
corporate version of the crystal iconset in the past few weeks/months. It
will be shipped with KDE 3.1 as the new default.

> oh, and window deco/ theme? LIQUID.

The default for 3.1 will be keramik. It's fast and original.

> what do you guys think?

You are right. And we have been working on this all the time until now.
If you want to contribute tell us what you want to take care of.

Weren't you the guy who created artwork for Mandrake? Do you like to work
with vector graphics and can you adapt other people's style?

No, he's just childish and clueless. According to one of our developers we'll have SVG-icons in KDE by the end of this week. That might be too late for KDE 3.0 but who cares anyways? SVG support is technically nice and might have quite some benefits in the longterm - but not for now. - Feb 12 2002

Icon Sub-Sets by JabberWokky 4 comments

There are two bugs in your icontheme-file:

1.) rename your "action"-directories to "actions" ("actions" is what you specified in index.desktop - of course you could also just change "actions" to "action" in the index.desktop-file as an alternative solution)
2.) Replace Context=actions with
Context=Actions in your index.desktop-file. "Actions" is one of the Context your theme inherits from. Therefore the Context has to be named the same in your theme. Otherwise KDE won't be able to map the icons correctly

Slick Icons 1.5 pre2

Icon Sub-Sets by Amibug 168 comments

KDE 3.0 will ship with alternative Iconthemes. "Slick" will be one of them.
We will only ship iconthemes with KDE 3.0 which don't have any known copyright-issues.
The default-icon-theme for KDE 3.0 will be "hicolor". Hopefully some of the icons from other iconsets will continue to replace/influence/improve those from "hicolor".

Hehe, that's what we used in one of the first beta's of KDE 2.0. The reason for having an abstract "internationalized" version of the stop-sign now instead (that's what the current stop-icon is meant to be) is that it looks easier on the eyes than a traffic-light.
