Hi,
I gave myself a headache today chasing bugs because I had a class which had an
osg::ref_ptr as a (private) member. gcc threw compile errors
referring to the destructor for osg::TemplateArray being protected, which it
claimed was being called by my class's (empty) destructor. My class did no
Hi,
I wonder if anyone can offer some insight on why I may be experiencing these
random crashes.
Essentially I have many line intersection visitors following a node which is
moving through the scene and performing line intersections on terrain, which is
a pagedLOD database of proxynodes.

Hi,
I'm writing an application to render a mesh generated from a stream of 3d
points, so that the mesh is updated in realtime to include points as they are
added.
It doesn't necessarily need to be a delaunay triangulation, but that seemed
like a reasonable place to start. The osg::DelaunayTria
Hi all.
I have two osg::Groups, one which is being rendered in my viewer and another
which is used as a buffer that collects geodes as they are created.
Periodically, I want to flush the contents of my root group and copy over all
the contents in the buffer.
I have tried several methods of cop
Thanks for the advice!
I'm getting closer but not quite there yet.
I found that my drawable in this test case has exactly one parent, and his
parent has a state set. I am able to get the image attached to the texture on
this state set without running across any null pointers, and write the ima
Hello,
I have a large terrain map which I load from an *.osg file containing a list of
ProxyNode objects containing *.ive files, using osgDB::readNodeFile.
My end goal is to get RGB of points on the texture map found through a line
segment intersection.
I have read through the mousePosition fu
Thanks so much. I will have a look at those examples. I don't need rotation
capabilities, only translation, scale, and color as you said.

Hi,
I have a scientific visualization application in which I essentially want to
render many (hundreds of thousands) of cubes at once, of varying color and
size. Furthermore, these cubes will change position and color every few
seconds, and I need to position them deliberately.
Right now I am
I took another look through the osgviewerQt source and found a solution, though
I'm not sure I understand why my extra step is necessary:
Manually initializing the projection matrix for the camera using
setProjectionMatrixAsPerspective fixes things.
Code:
camera->setProjectionMatrixAsPerspect
Yes, oddly enough it works just fine.

Hi All,
I have a simple Qt4 wrapper for my OSG 3.0 application which employs the
trackball manipulator. The left and middle mouse button functions in the
manipulator work as expected, but the right mouse button does not seem to do
anything, which makes the manipulator kind of useless.
Is this
