Re: [osg-users] Has anyone tried 64-bit SUSE enterprise
Hi Brede, Does the onscreen help cause the same performance slow down, or is it just stats. The difference being that help is static text, and stats is being dynamically update. The cost should be pretty negligible though - the stats scene graph is trivial in size. With the stats I have found that text is relatively slow to update, suggesting a need for a rewrite of osgText further down the line, but.. the currently implementation should not go leaking like you have found, this suggest another problem all togther.

Re: [osg-users] ECW Image Files - Secret Tricks?
Antoine, So how do I make sure that the osgdb_ecw.dll plug-in gets called instead of GDAL? As it is, osgDem just stops (crashes actually...). I am not looking foward to recompiling GDAL ;( - Nick - I meant that OSG plugins are called in sequence, each plugin is trying to load the file and returns either an image handler or an error code. The way the GDAL plugin is trying to read a file is to open a GDAL dataset from this file. If it fails the operation returns a null pointer to the plugin but also displays an ERROR 4 message. Then the plugin is returning an error code. If later on an other plugin is able to open this file, you do not need to care much about the GDAL error. Recompiling GDAL with ECW support would also work but would make the ECW plugin useless. (PS: Peut-etre pouvez-vous m'expliquer en francais. Merci pour le coup de pouce.)

[osg-users] Text - SCREEN_COORDS
Hi,
I would like to display text with constant size in pixels, so I have
used CharacterSizeMode as in the simple code sample below:
/ code start
#include osg/ref_ptr
#include iostream
#include osg/Geode
#include osgText/Text
#include osgText/Font
#include osgViewer/Viewer
osg::ref_ptrosg::Node createSceneGraph() {
//this create geode with text C++
osg::ref_ptrosg::Geode textGeode = new osg::Geode;
osg::ref_ptrosgText::Font font = osgText::readFontFile(fonts/arial.ttf);
osg::ref_ptrosgText::Text text = new osgText::Text;
text-setFont(font.get());
text-setFontResolution(256,256);
text-setText(C++);
text-setAxisAlignment(osgText::Text::SCREEN);
text-setCharacterSize(500);
//this is the problem
text-setCharacterSizeMode(osgText::Text::SCREEN_COORDS);
textGeode-addDrawable(text.get());
return textGeode.get();
}
int main(int, char **) {
osg::ref_ptrosg::Node root = createSceneGraph();
osgViewer::Viewer viewer;
viewer.setUpViewInWindow(0,0,1000,300);
viewer.setSceneData(root.get());
return viewer.run();
}
/ code end
But the problem is that the text is contracted. It has right proportion
only when I use squere window. I could see the same efect also with
the osgtext example (more clearly if you use higher aspect ratio window).
I am using widescreen display but it should be no problem.
Did I forgot something or is it standart behaviour when using SCREEN_COORDS?
And also the real text size is not what I requested (500 pixels).
Here is image of the sample window:

Thank you,
Martin

Re: [osg-users] ECW Image Files - Secret Tricks?
Hi Nick, I think there is a misunderstanding of how osgdem works. The OSG readImageFile method, which invokes the plugins you are talking about, is not used in osgdem/VPB currently: it uses the GDAL library directly. I don't want you all to go down the wrong path trying to tweak OSG plugins that will have no effect. As far as recompiling GDAL to get ECW support, I would suggest trying to download the binary releases of GDAL included in the FWTools package ( http://fwtools.maptools.org/). The sight is down this morning, but should be back up at some point. It has almost all the optional plugins built for you and I'm pretty sure ECW is supported out of the box with those libraries.

A lot of text to analyse but the only way to verify that the ECW plugin is in the list.

Hi Robert, The VPB state seems appropriate to me, I'm not sure what else need to be added. I know it works but performance over the internet is just not really anything like GE (OSG1.2). Maybe 2.x is faster... maybe it is our web server...
