Re: [osg-users] [3rdparty] SpeedTree 6.0 integration
Hi Michael I wonder if your SpeedTree and terrain rendering is doing ok? We are about to integrate SpeedTree and we use paged/tiled terrain aswell. Can you provide example code of how you integrated the SpeedTree classes and shaders into OSG? and also share some insights on the issues you faced? I would be grateful!

[osg-users] Controlling simulated time
Hi, Is there an easy way of controlling the simulated time without creating a Viewer subclass and re-implementing the run method? I have a pseudo loader plugin that interfaces the HLA world and manipulates the scene graph. What I basically want is the setting of the simulated start time and the time scale.

Re: [osg-users] Controlling simulated time
HI Arend,
The viewer::run() method is just a convenience method, which is great for
small examples that want to illustrate other things than the make up for
the frame loop, however, for full blown apps I would typically recommend
just rolling your own frame loop. The next simplicist form of frame loop is
to expand the viewer.run() method to something like:
while(!viewer.done())
{
viewer.frame(simulationTime);
}
To further expand it you'd have:
while(!viewer.done())
{
viewer.advance(simulationTime);
viewer.eventTraversal();
viewer.updateTraversal();
viewer.renderingTraversals();
}
You have access to all the source code of the OSG so I'd encourage you to
look at the implementations on the Viewer::run() and Viewer::frame()
methods so you see what is happening under the hood.
Robert.

[osg-users] State of Qt5 integration?
Hi all, is anybody still working on integrating Qt5? It seems that CMake now runs smoothly, but I could not get the osgviewerQT example running on Windows 7. I see the Qt widgets, but the OSG windows are all black and the console is flooded with OpenGL errors. This is using Qt 5.2 64 bit on Windows 7. Has anyone managed to get both of these beasts running together? Thank you!

Re: [osg-users] Controlling simulated time
Hi Robert,
Your proposed solution is not what I really want. I would like to have a
capability where I can alter the behaviour of the simulated time determination
from within a plugin without write my own Viewer class. This allows me to use
the OSG software as is without writing my own stuff.

Arend

Re: [osg-users] State of Qt5 integration?
I just played around a bit and managed to get a very simple integration.
It is a bit cheating, I simply take an OSG window and add it to a Qt widget.
* No fancy Qt stuff supported like drag and drop, overdrawing etc.
* Only windows (although Linux should be no problem after some modifying)
* Multithreading not a problem here
* Should run with Qt 5.1 or newer
Code:
#include osgDB/ReadFile
#include osgGA/TrackballManipulator
#include osgViewer/Viewer
#include osgViewer/api/win32/GraphicsWindowWin32
#include QApplication
#include QHBoxLayout
#include QSlider
#include QTimer
#include QWidget
#include QWindow
#include assert.h
int main(int argc, char** argv)
{
if (argc2)
{
std::cout argv[0] : requires filename argument. std::endl;
return 1;
}
// Create Qt app
QApplication app( argc, argv );
// Create OSG Window
osg::ref_ptrosgViewer::Viewer viewer = new osgViewer::Viewer();
// setup viewer
{
viewer-setUpViewInWindow(0,0,800,600);
viewer-setCameraManipulator(new osgGA::TrackballManipulator);
viewer-setSceneData(osgDB::readNodeFile(argv[1]));
viewer-realize(); // else window does not show
}
QWidget* mainwidget = new QWidget;
mainwidget-setLayout(new QVBoxLayout());
mainwidget-resize(800,600);
mainwidget-show();
// Add osg window to main widget
{
osgViewer::ViewerBase::Windows wins;
viewer-getWindows(wins);
// Get native windows HWND window id from OSG window
osgViewer::GraphicsWindowWin32* osgwin =
dynamic_castosgViewer::GraphicsWindowWin32*(wins.front());
assert(osgwin);
HWND winid = osgwin-getHWND();
// Create a QWindow from osg window id and place it in a widget
QWindow* qtwindow = QWindow::fromWinId((WId)winid);
QWidget* osgwidget = QWidget::createWindowContainer(qtwindow);
osgwidget-setMinimumSize(QSize(320,200));
// Add osg widget to a main widget
mainwidget-layout()-addWidget(osgwidget);
}
// Add a slider changing the background color
{
QSlider* slider = new QSlider(Qt::Horizontal, mainwidget);
slider-setRange(0, 255);
mainwidget-layout()-addWidget(slider);
// Connect to lambda
QObject::connect(slider, QSlider::valueChanged, [=](int v) {
viewer-getCamera()-setClearColor(osg::Vec4((float)v / 256.0f, 0, 1, 1)); });
}
// Make Qt call osg tick
{
QTimer* timer = new QTimer(mainwidget);
timer-start(20);
QObject::connect(timer, QTimer::timeout, [=]() { viewer-frame(); });
}
app.exec();

Re: [osg-users] [3rdparty] SpeedTree 6.0 integration
My group is also implementing SpeedTree and having some trouble. Any help would be greatly appreciated. I managed to isolate OSG's OpenGL state by enabling glPush/glPop statements in the SpeedTree library (I know this isn't optimal), but I still can't get the 3D trees to render. Billboard trees are working (minus smooth fading between angles).

As for setting the simulation is some generic plugin that existing OSG applications know nothing about, then sorry the OSG hasn't been designed that way, plugins can load/save data or provide nod extensions, but things like timing is the role of the viewer. Please remember the OSG is a scene graph library, it's not an end user application. It's there to help you write your applications, it's not their to provide applications.

Re: [osg-users] Graphics Context question
I am using different graphics contexts simply because I want to display the texture(s) in a separate window from the window in which my original scene is rendered. Is it possible to have 2 windows which share the same context, but have different scenegraphs? How would I create the shared context?
