[osg-users] ImageStream current frame
hello,
I would like to display what percentage of a video has been played. I'm
using the ImageStream class and I thought getReferenceTime() or
getTimeMultiplier() might help me, but they always return 0.
Examining the header file I found this:
72 virtual double getLength() const { return 0.0; }
73
74 virtual void setReferenceTime(double) {}
75 virtual double getReferenceTime() const { return 0.0; }
76
77 virtual void setTimeMultiplier(double) {}
78 virtual double getTimeMultiplier() const { return 0.0; }
So it seems this functionality is not ready yet. Does anyone have an
alternative way to determine the current playing video frame?
regards,
Richard

Re: [osg-users] ImageStream current frame
thanks for the clarification about ImageStream Robert.
If I understand right ImageStream buffers the frames in a PixelBufferObject
and switches the frames in the compileBuffer() function. So if I could get
feedback from this function then I could determine the frame count. Possibly
the _compiledList[contextID] variable might help with this.
Am I on the right track? Can you offer any advice?

Re: [osg-users] ImageStream current frame
I'm happy to extend ImageStream if my changes could be fed back. "The changes will need to be to base class and the ImageStream implementations." Frame information would only be relevant to a stream so why would the base Image class need to be changed?

[osg-users] extracting camera path from model
hello,
I have a model and camera animation path exported from 3ds max to osg
format.
In OpenSceneGraph I want to jump to any point along this animation, so I'm
trying to extract the AnimationPath ControlPoints.
Here is the relevant part of the osg file:
PositionAttitudeTransform {
DataVariance DYNAMIC
name "Camera01"
nodeMask 0xff
cullingActive TRUE
UpdateCallbacks {
AnimationPathCallback {
DataVariance DYNAMIC
pivotPoint 0 0 0
timeOffset 0
timeMultiplier 1
AnimationPath {
DataVariance DYNAMIC
LoopMode LOOP
ControlPoints {
0 235.432098388672 9.58514785766602 0 0.500558972358704
0.499440401792526 0.499440401792526 0.500559031963348 1.0011920929
0.99761581421 1.0023841858
...
So you can see the AnimationPath is stored within a callback within a
Transform. My problem is I haven't figured out how to extract this path.
There was a similar thread on this earlier (
http://groups.google.com/group/osg-users/browse_thread/thread/f89d14baf366385b/1c9e025662bf2544)
but the author was just after an initial position.
I looked at getUpdateCallback() but the interface of its return type
NodeCallback looks like a dead end.
Has anyone done this before?
regards,
Richard

[osg-users] TrackballManipulator asymptote
hello, when I use the TrackballManipulator to view my model I find that the camera velocity slows to zero if I try to approach a certain point, which I believe is the origin. Do you know why this occurs and how it can be prevented?

thanks again Robert - now I better understand how TrackballManipulator works. I overloaded the calcMovement() function to move consistently and it is working well.

[osg-users] multiple views on separate Qt widgets
hello, I am trying to provide multiple views of an OpenSceneGraph scene within a Qt window. I can get this working for a single view, or multiple views in the same widget like in the osgviewerQT composite example. But I'm struggling to get multiple views on separate widgets working. I know many variations of this question have been asked: http://www.mail-archive.com/osg-users@lists.openscenegraph.org/msg08512.html http://www.mail-archive.com/osg-users@lists.openscenegraph.org/msg04883.html http://www.mail-archive.com/osg-users@lists.openscenegraph.org/msg05487.html http://www.mail-archive.com/osg-users@lists.openscenegraph.org/msg16623.html etc But I am still not clear how to render each view. The examples use composite_viewer->frame() in the paint event but for me this only renders a single view and leaves the rest blank. Is there an alternative way to render multiple views at the same time?

Re: [osg-users] multiple views on separate Qt widgets
hi Robert, I've tried both methods used in the example and got both working for a single view, but not for multiple. The problem seems to be with having separate timeout loops calling composite_viewer->frame(). Is there an alternative way to render a view?

The examples I've seen put frame() in their paint event and don't render without it there.

[osg-users] ShadowMap is wiping out ambient light
hello, when I add a shadow map to my scene it wipes out the ambient lighting. Searching the archives I noticed a thread from May with the same problem: http://lists.openscenegraph.org/htdig.cgi/osg-users-openscenegraph.org/2008-May/011559.html But the discussion in that thread ended without resolution. Has there been progress on this issue? Or is there a neat work around? v2.6.1 Richard ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] Model progress after loaded
hello, I am using the model loading progress example provided by Marco Jez at http://www.openscenegraph.org/projects/osg/wiki/Support/Tutorials/LoadingProgress It is a neat effect but I have found there is a delay after the model is loaded before it is shown in an OSG view. I expect this is because after the model is loaded it still takes some time to render. Is there a way to determine when a model is viewable by the user? thanks, Richard ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] multiple views on separate Qt widgets
hi, the 2.6 screenshot shows the expected functionality (the right panel is a top down view). The problem is in 2.8 my composite views are rendered on the desktop instead of within the window. Can you think of a reason for this? I suspected the problem is how I create the view in the SceneOSG::addView() function.

[osg-users] CAD style rotation
hello, I am after an osgManipulator with CAD style rotation. In a typical CAD program the rotation keeps the roll fixed and orbits around the centre of the screen. In contrast the TrackballManipulator allows the roll to change and rotates around the origin.

it in code like this:

// moon seems buggy so just set sun

> boundary.top() + boundary.height()/2, 0));
