Hi Dirk,
I think I fixed all occurrences
now, please give it another try.
I downloaded the dailybuild 051208, installed, recompiled the example, and ...
It's working !!!!!!! Dirk, you are *THE MAN* !!!!!! Thanks so much!
After few months of trouble, it was so pleasant to see the OpenSG
example model
together with the VRJuggler avatar, I thought I'd never see it ! I must
therefore drop some screenshots of the previously linked examples:
This is the simpleVolumeNodeRender in VR Juggler - the one which
anyways bugs on
my machine in debug. Still bugs (white screen), but the avatar is
there, and no
crash

The release is of course fine:

This is the example with DVRMtexLUTShader, which on my machine works fine both
in debug and release mode

I couldn't imagine the model is so big in the VR Juggler environment,
so I tried
to scale it - it was not totally straightforward for me, so I thought
I'd share
the code for makeVolume below, with the scaling stuff included - maybe
it helps
someone:
// Create a volume rendering node with all desired attachments
OSG::NodePtr OpenSGNav::makeVolume( const char * datFile)
{
OSG::DVRVolumePtr vol = OSG::DVRVolume::create();
OSG::DVRAppearancePtr app = OSG::DVRAppearance::create();
OSG::DVRVolumeTexturePtr tex = OSG::DVRVolumeTexture::create();
// Load the 3D-image and store it in the volume texture attachment
OSG::ImagePtr datImage = OSG::Image::create();
if (false == datImage->read(datFile)) {
SLOG << "File: " << datFile << " not found" << std::endl;
//exit (-1);
exit();
}
OSG::beginEditCP(tex);
tex->setImage(datImage);
tex->setFileName(datFile);
OSG::endEditCP(tex);
// Attach the volume texture to the appearance
OSG::beginEditCP(app, OSG::Node::AttachmentsFieldMask);
app->addAttachment(tex);
OSG::endEditCP (app, OSG::Node::AttachmentsFieldMask);
// Assign the appearance to the volume core
OSG::beginEditCP(vol);
vol->setFileName(datFile);
vol->setAppearance(app);
vol->setShader(OSG::DVRSimpleShader::create());
OSG::endEditCP(vol);
// Create a node for the volume core
OSG::NodePtr newGeom = OSG::Node::create();
OSG::beginEditCP(newGeom);
newGeom->setCore(vol);
OSG::endEditCP(newGeom);
//scale it a bit
OSG::TransformPtr mVolTransform = OSG::Transform::create();
gmtl::Vec3f scaler = gmtl::Vec3f(0.05f, 0.05f, 0.05f);
OSG::Matrix scale_mat(OSG::Matrix::identity());
scale_mat.setScale(scaler[0], scaler[1], scaler[2]);
OSG::beginEditCP(vol);
mVolTransform->getMatrix().multLeft(scale_mat);
OSG::endEditCP(vol);
OSG::NodePtr scaledGeom = OSG::Node::create();
OSG::beginEditCP(scaledGeom);
scaledGeom->setCore(mVolTransform);
scaledGeom->addChild(newGeom);
OSG::endEditCP(scaledGeom);
//return newGeom;
return scaledGeom;
}
Thanks again,
Cheers
