Hi Su Hu,
Do you mean the you are using osgParticle::PrecipitationEffect to render the
rain and snow, or do you mean you've modified the osgparticle example?
The warnings look like graphics context setup issue, do other examples work
fine?

Hi all,
Hi,
I notice that calls like EventInterface::addCallback(new Callback(...))
would cause memory leak.
It use a list to manage the callback objects, and the list item is
osg::observer_ptrCallback, but not something like osg::ref_ptrCallback.
And observer_ptr doesn't do ref/unref to Reference

I am trying to set the camera perspective projection to 'near'
orthogonal. I achieve desired projection by setting the FOV to some low
number (1.0).
When the projection matrix is changed in this way, the scene is
'zoomed-in'. This means, that MatrixManipulator::home does also

FLTK 2 has not been officially released. It has been under development

Hi Paul,
Thanks for the reply. I'm using OSGCONV to convert FLT file to IVE. I will
try bumping up the notify level and see if that provides any clues. I will
also try v2.8.
Thanks again,

Read this topic online here:
You can either use a true orthographic projection, or you can set the
TrackballManipulator home position so that the viewpoint is further away. If
you are really trying to create a near orthographic (but not a true
orthographic) projection, then setting the eye distance very far away is the
right
Then when you said you were using the same models, I guess you meant you

I have been running Windows 7 beta for a few weeks now at home (being

sorry for the delay i tried your example it works perfectly here with

I guess you have maybe a problem with your library like compiling in

Hi Charles,
My attempted process to close is that I (1) set a flag on a render thread to stop
calling viewer-frame (very similar to setDone(true)); (2) destroy the loaded
drawables and free their associated libraries; (3) destroy the view, and thus it's

Is there any interest in supporting Xinerama calls to determine what the

I submitted it mostly in case there was anyone out there who wanted to

Chuck,
I have had similar issues (with crashes in releaseGLObjects when views get
destroyed) but can't actually recall what I did to fix them.
You could try calling viewer-releaseGLObjects() before you destroy the
view. (previous posts seem to suggest that this might be the right thing to
do)
Sorry I meant an ordinary Hud as in the osghud sample.

the Camera's View and Projection to allow screen-space rendering (just as you
would for any normal HUD).
That's what I did.
