Hi Anders,
In our application I have made 2D plots using CAIRO (
http://cairographics.org/), it's really a light and easy to use library to
draw in 2D, you can make very nice effects. I have integrated it with CEGUI
to render my graphs into a UI window.

Hi Mke,
I haven't heard anyone trying to do this, stripping out OpenGL is
quite a major change and would be a lot of work. Perhaps what you
could do is create a dummy OpenGL library that provides the headers
and an non op implementation. One might even be able to do all this
with just macros.
I'll make the try to see what happen. Here I just wanted to point out that
the problem origin may be in a function called in a thread when no
particular setting on the osgviewer instance is done.
If the try succeed, I guess I will have an unrecoverable crash even with the
Release executable
Hi Jason,
I have the very same problem : having to implement a new visual application, I
must now choose between a C# implementation and a C++ unmanaged one.
As you can bet, I'd largely prefer the first option (for instance I've

Hi Robert,
Thank you for responding. I've been experimenting for hours, with the
'opengl programming guide' on my desk, but no luck.
In my small test program the initial view distance to the centre of my
scene is about 250.
I would expect the following to work but is does NOT:

The stats are collected into the osg::Stats objects, have a browse
through the src/osgViewer/StatsHandler.cpp to see how it's used.

Hi @ all,
I'm working on an project for importing the COLLADA models out of a
KML file into OSG.
Reading of needed attributes and coordinate transformation works fine
with GDAL/OGR library and invoking the OSG plugin for importing
COLLADA .dae files works almost perfect too...
I'm using OSG 2.1.7

Of course I would like to never change a running system :)
I don't recall any bug fixes for these issue you are reporting.

Hi Richard,
The OSG uses post multiplication, if there are any exceptions to this
then they are bugs, it doesn't mean everything is messed up or OSG
maths is generally wrong. Is it only Vec3 * Quat is wrong in your
investigations? Could you add a unit test to the examples/osgunittest

I will have to do the same thing as you (only one intersection). I think
to inherit from IntersectVisitor and overloading apply(Geode) and
cut/paste the intersect drawable with small changes to return after one
hit. It means to duplicate code.
Maybe there is something better to do that.
I worked on a plotting system using OpenSceneGraph not too long ago.
Speed was a very important factor for us because we were dealing with
real time data. My experience with GNUplot is that it's not very good
for this type of situation.
OpenGL gave us a lot of power to be able to zoom and
Hello Glenn,
Is there a way to tell the osgUtil::IntersectionVisitor to stop searching
once it finds one (or n) intersections?
I don't know about IntersectionVisitor, but Adrian Egli's kdTree
implementation for OSG supports this (in that case, it's to make
raytracing shadows faster - you
Just to clarify here, are we changing the way things work, or simply
adding another operation?
If we change the way things are working, hopefully it will be reflected
strongly in the release notes.

If this is a bug (I'm imaging it is) then you should probably submit it

Hi Hans,
have you tried other values for start/end, things like start=10, end=1000?
From what I can see you're setting up a grid of objects in the range
x=-50..50, y=-50..50 so the grid is merely 100x100 units in size. Depending on
where your camera is (probably determined by the manipulator
Hi,
you're setting up a texture on your geode without actually setting texture
coordinates. OpenGL will helpfully ;-) pick up coordinates from the last
textured object for you.
