[osg-users] osgManipulator dragger switch
Hi could s.o. give me a short hint how I could attach different draggers to one node and switch between these draggers ?

Re: [osg-users] osg+QT MODKEY How to
Hi Legeo
I had a similar problem - using osg, qt4 and the AdapterWidget example.
In AdapterWidget::keypressEvent (...)
osgGA::GUIEventAdapter::KeySymbol) * (event-text().toAscii().data() returns
0 in the call
_gw-getEventQueue()-keyPress( (... ) ) for keys like:
Qt::Key_up ... Have a look at the Qt documentation Qt::Key.
I have managed it with:
int c = *event-text().toAscii().data();
if ( c == 0)
{
switch (event-key())
{
case Qt::Key_PageDown:
_gw-getEventQueue()-keyPress(
osgGA::GUIEventAdapter::KeySymbol::KEY_Page_Down );
break;
case Qt::Key_PageUp:
_gw-getEventQueue()-keyPress(
osgGA::GUIEventAdapter::KeySymbol::KEY_Page_Up );
break;
case Qt::Key_Up:
_gw-getEventQueue()-keyPress( osgGA::GUIEventAdapter::KEY_Up);
break;
}
}
else
_gw-getEventQueue()-keyPress( (osgGA::GUIEventAdapter::KeySymbol) *
(event-text().toAscii().data() ) );
There might be a better solution but it works.

Subject: [osg-users] osg+QT MODKEY How to
Hi all,
I'm trying to add a Modkey event handler to my application with osg and
qt4. But it seems that the getModKeyMask() fuction fails to work. Return
value of getModKeyMask() always is 0, even if I have a MODKEY pressed. And,
this is my code:
if ( ea.getEventType() == osgGA::GUIEventAdapter::PUSH
ea.getButtonMask() ==
osgGA::GUIEventAdapter::LEFT_MOUSE_BUTTON
ea.getModKeyMask() == osgGA::GUIEventAdapter::MODKEY_SHIFT )
{
/*-
do something here
-*/
}
How can I handle it? Thanks in advance!
cheers
legeo

Therefore I have managed the views similar to setUpViewFor3DSphericalDisplay and setUpViewForWoWVxDisplay. However I can't figure out how to set the projectionOffset and viewOffset in addSlave (I have read all mails concerning addSlave, but I haven't found a solution).

Present3D is also under the GPL, so if you wish to make a derivative work, such as what you describe, it will also have to be GPL'd. If your app is GPL'd and want to move to integrating with Present3D in some way, then it might be possible to set Present3D to use a single view within a Viewer. Present3D is a bit of tangled mess in the main, and awaits a rewrite that I'll be doing over the next year, so it might be possible to move things in a direction that is more interoperable. Robert.

However, you're not setting the Material properties (ambient, diffuse, specular, emissive, shininess) and the default values for Material are unlikely to match that of the node you're trying to blend. Hence when you override the original material it will switch from the original settings to the default Material. For an experiment, have a look at any .osg file and look at the material properties. Then set those values on the 'blendMaterial' node you're creating and it should look smooth. You're probably better off modifying the original Material(s) of the node hierarchy. Or try another approach, like using blendcolor.

Re: [osg-users] cloned node without texture
Hi
it seems that for my purpose -
clone(osg::CopyOp::DEEP_COPY_NODES);
is the best one (geometry and texture)

[osg-users] multiple texture loading of identical objects
Hi when I start osgViewer with e.g. 29 identical objects(.flt) , the framerate is about 30 fps, but starting with 30 identical objects the frame rate drops down to 1 fps. This has s.th. to do with the texture , when I press 't' the framerate increases to 30 fps. Is it possible to load the texture only once and not every identical object (similar to SGI pfuDownloadTexlist) ?

Hi Colin it works with a low cost webcam but not with a more expensive one - so it has s.th to do with the webcam Thanks Dieter -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Colin Dunlop Sent: Thursday, 19 June, 2008 17:53 To: OpenSceneGraph Users Subject: Re: [osg-users] Quicktimeplugin livestreaming documentation/examples Hi Dieter, did you actually change your webcam settings to default the webcam to use 640 x 480 by default (prior to running 0:3.live)? Did you see osgmovie with a higher resolution (live stream) on windows ? Any other hints? Yes my webcam will do 1024x768 and various downward resolutions ok. This is using AbstractPlane wrapper and setting the camera resolution up in advance via it's settings prior to running osgmovie as said. My capture card does full 1080p via HDMI and this is also captured successfully via osgmovie as well as various flavours of PAL via composite in eg 576i. This card has a native QuickTime driver though for Windows (rare) and is accessed without the DirectShow wrapper. As far as any hints I have found that the AbstractPlane wrapper will sometimes not offer ALL the resolutions of the DirectShow devices and only a subset? The plug-in was intended for native QuickTime drivers on OSX/Windows and the fact it works via the AbstractPlane wrapper is just a bonus but is an indirection that the OSG or the plug-in has any control over regarding problems. Let me know if you have any success. Cheers, Colin. Dieter Pfeffer wrote: Hi Colin thanks for your answer - but I have no success with a higher resolution.

Subject: [osg-users] Adding input device Part 2
Hi,
As some of you may remember, i was trying to add a new input device
to my OSG application. This device was the SpaceNavigator. I had access to
the code that gets the 3D coordinates from it any time it is activated. But,
when it is idle, that code makes my application stop and wait for any signal
from SN. I was inserting that loop in the event type FRAME. But, as you may
imagine, when I stopped moving with SN, my application entered that waiting
stage, and the regular cycles of traversal, culling and drawing were
blocked.
Someone else suggested that I added this device in a new Event
Handler class. Is that right? How do I do that, exactly? Any examples?
Thanks,
Renan M Z Mendes

The next frame event should trigger the manipulator to update its position accordingly. The DriveManipulator::setNode(osg::Node* node) method will currently override the _height value, this will be called if you viewer changes its scene graph. Perhaps this is what is causing problems. If so then try using putenv/setenv to set the OSG_DRIVE_MANIPULATOR_HEIGHT env var to the value you want. Robert.

Hi Dieter,
Unfortunately the info below doesn't really give me much more of an
ideal of where the problems has stemmed from. Could you try a debug
build and see if you can catch the location of the problem.
As a general note about particle effects which are being transformed,
what you will need to do place the particle system itself at the root
of your scene graph, rather nested in the scene graph, as you should
be emitting particles into the air rather than local to the particle
source. The osgparticleeffects example provides an example of this.

Hi Dieter,
Things should certainly not hang so this is a bug. Could you break
the app and find out where its hanging.

This is my hierarchie::

The object is moving by: osg::PositionAttitudeTransform -setPosition /

What do I wrong ?

Re: [osg-users] RTT in a multichannel app
Robert, I meant the view offset of the offset slaves (left: -40; right 40) The RTT camera is in the scene graph itself - but I have one scene for the three cameras; I thought I need three RTT cameras, one for every channel; but when I set the ReferenceFrame to RELATIVE_RF, I suppose I have the view matrix of the center camera for all three RTT cameras or do I misunderstand something ?

The same view offset as what? The master camera? One of the already offset slaves? For a RTT slave to have the same view matrix as the master simply use an identity matrix. If your RTT Camera is in the scene graph itself then just set its view matrix to identity and then set the ReferenceFrame to RELATIVE_RF.

[osg-users] differences between osgViewer and osgCompositeViewer
Hi when I load an object with a generated internal sequence, I can see this sequence automatically in the osgviewer example but not in the osgcompositeviewer example. I have a similar point when I set an AnimationPathCallback in a CompositeViewer application, I have modified the osgparticleeffects example and use osgViewer::CompositeViewer, but then the model is not animated. Is it possible to activate in my application which uses osgViewer::CompositeViewer (multi views and multi scenes) the sequence automatically ?

[osg-users] Plugin find - linux
Hi I have with osg2.1.6 a similar problem (like the plugin find behaviour discussion) with the plugin path: I get the message: could not find plugin to read objects from file xxx.flt; but the viewer has no problem to find xxx.ive or xxx.osg files; so I suppose the directory structure and path is correct. The OpenFlight lib is in the plugin directory.
