Hi J-S,
thanks for your feedback. If have to confess that yesterday evening I only
compiled and added, I have not yet tested all new functions. At least the
compile process with OSG works well in 32 and 64 bit.
Regarding the 32 / 64 bit issue with libjpeg and libpng:
I can't understand why
Hi everyone
I'm using GLSL shaders with OpenSceneGraph for some scientific
visualisation. I've got sample values in a n*m floating point texture,
and a colour lookup table in a 1-D texture.
I'm sticking those textures on a osg::TexturedQuadGeometry like this:
Hi,
you can try explicitly setting the texture filter, e.g.
OutTex-setFilter(osg::Texture2D::MIN_FILTER, osg::Texture2D::LINEAR);
OutTex-setFilter(osg::Texture2D::MAG_FILTER, osg::Texture2D::LINEAR);
and leave out any mipmap settings.

Hi, Grahame
I'm not sure if i get it right, but seems like you need to change texture
filtering modes on each texture (to nearest i suppose) or you can use
texelFetch function in shaders instead of texture*, it overrides texture
filtering rules and returns exactly value stored in specified

My setup now is:
Code:
viewer = new osgViewer::Viewer();
shadowedScene = new osgShadow::ShadowedScene();
scene2d = new osg::Group();
root = new osg::Group();
viewer-setUpViewOnSingleScreen(0);
windowManager = new osgWidget::WindowManager(viewer,width,height, MASK_2D);
osg::Camera* camera =
Thanks a lot!

Hi Torben,
To NVTT: I did not simple pack the binary version of NVTT, because I don't know
about the license. As the source code is MIT licensed, I rebuild it in Release
mode for 32 and 64 bit. For the packaging and usage in OSG there was no obvious
requirement for libjpg or libjep. After my

When i used osgppu i've experienced several frames delay (1 to 3 frames, not
sure if this delay is persistent or it shows up from time to time, threading

Hi all,
I am using osgViewer::Viewer in ON_DEMAND RunFrameScheme, e.g. there is no
continual re-rendering and 100% CPU loading, but the scene is rendered only
when really needed.
Bug: The window is not repainted when obscured by another window and re-shown
again.
I was trying to fix the

ok, this is the cuestion: i try to make a slider in osg, someone toldme taht

little proyect that show a window with label, but i dont know how make it work
in OSG
any help would be appreciated

Interesting problem you've unconvered. Responding to windowing
redraw events is something it should do, but alas it wasn't something

Thanks for your quick reply, good to know it can be done with osgVolume. I will

osgvolume --images *.dcm
The images load without any
