Re: [osg-users] [build] Could NOT find osgDB (missing: OSGDB_LIBRARY)
I have installed myself using command : Code: cmake -G Unix Makefiles make sudo make install with previous command include are in /usr/local/include and lib in /usr/local/lib64 So now I have set OSG_DIR=/usr/local/lib64 and may be now I have a standard place for OSG is it right?

[osg-users] Sending fake mouse events to a TrackballManipulator? (again)
Hi,
I need to simulate mouse inputs for a basic test application.
Following Robert's advice [1], I'm injecting mouse events to the event
queue of the viewer's application.
My implementation is very similar to the one in
GraphicsWindowWin32::handleNativeWindowingEvent.
But a mouse drag (independently of the mouse button: left, middle,
right; don't understand why) rotates the scene around the axis
perpendicular to the display (Oz I presume). And there seems to be a
huge threshold somewhere, as the scene is rotated several times while
I'm dragging the mouse very slightly.
To sum up, I'm getting no 3D rotation, nor panning or zooming, only
flat 2D rotation around the Oz axis. Does this strange behavior
suggest something obvious that I'm missing?
If helpful, my code looks like this:
void transformMouseXY(float x, float y)
{
assert(g_viewer.valid()); // g_viewer is a global
osg::ref_ptrosgViewer::Viewer
assert(g_viewer-getEventQueue());
if (g_viewer-getEventQueue()-getUseFixedMouseInputRange())
{
osgGA::GUIEventAdapter* eventState =
g_viewer-getEventQueue()-getCurrentEventState();
// SCREEN_WIDTH and SCREEN_HEIGHT are two constant unsigned
integers
x = eventState-getXmin() +
(eventState-getXmax()-eventState-getXmin())*x/float(SCREEN_WIDTH);
y = eventState-getYmin() +
(eventState-getYmax()-eventState-getYmin())*y/float(SCREEN_HEIGHT);
}
}
void inputProc(unsigned int MessageID, const void* Data)
{
assert(g_viewer.valid());
osgGA::EventQueue* queue = g_viewer-getEventQueue();
assert(queue);
double eventTime = queue-getTime();
switch (MessageID)
{
caseMSG_LBUTTON_DOWN:
{
float mx = ((unsigned int*)Data)[0];
float my = ((unsigned int*)Data)[1];
transformMouseXY(mx, my);
queue-mouseButtonPress(mx, my, 1, eventTime);
}
break;

{
float mx = ((unsigned int*)Data)[0];
float my = ((unsigned int*)Data)[1];
transformMouseXY(mx, my);
queue-mouseButtonPress(mx, my, 2, eventTime);
}
break;

{
float mx = ((unsigned int*)Data)[0];
float my = ((unsigned int*)Data)[1];

}

Re: [osg-users] (no subject)
Hi Robert, Thanks for the quick answers. Please find attached the two modified files (originals are from version 3.3.3): The files are: - include/osg/BufferObject - include/osg/GLDefines Qt also uses the #ifdef #define pattern so switching include order might not be ideal (haven't tested...). I guess it is easier to change osg than Qt ;) But there is a somewhat related Qt bug open : https://bugreports.qt.io/browse/QTBUG-43748 Qt unnecessarily exposes GL constants publicly.

[osg-users] Cloning uniforms callbacks
Hello everyone. I just noticed that when I clone a node using the flags DEEP_COPY_NODES, DEEP_COPY_DRAWABLES, DEEP_COPY_CALLBACKS and DEEP_COPY_UNIFORMS then the callbacks of the uniforms are not cloned. As a result my cloned uniforms don't have any callbacks. I tried using other flags as well but it didn't change anything. Looking at the code I believe the Uniform(const Uniform rhs, const CopyOp copyop) constructor is lacking some lines to apply the copy operation to the callbacks (just like the Node copy constructor does for example). Is it me not using OpenSceneGraph properly ? Or is it a bug ? If so then can I propose a patch ?

Re: [osg-users] [build] Could NOT find osgDB (missing: OSGDB_LIBRARY)
Hi Laurent, It's not a Linux specific issue as it'll work fine if the heads and libs are installed in standard places. If your headers and libs are in a non standard place you'll need to tell Cmake where to look, either at first configuration or via the ccmake tool. For instance try setting the OSG_DIR env var to where you've put the OSG. If you are still having problems have a look at CMake's /usr/share/cmake-version/Modules directory for it's Find OSG related scripts. Robert.

If you do just let me know the changes required and we can then discuss how to tweak the OSG or it's Qt usage to avoid the issues. Robert.
