Hi Stephen,
Thanks for the response. When I do that below, the osg portion of the

That is on the latest 2.2 release. Might be

Are there other example apart from osgimpostor, possibly saved as .osg

Hi again !
I'm working on some kind of editor in fact, and I've noticed that when you
have a StateSet, and a given StateAttribute, if you call
stateSet-setAttributeAndModes(attribute,osg::StateAttribute:ON|osg::StateAttribute::...etc,etc..
) then, (at least for a osg::Fog attribute for example)

I have a program which uses shaders in osg (using osg::Program of course).
It works perfect on GeForce 8800, but on GeForce 7800 the shaders don't work
at all.

same picture I would get without running shaders.

Hello Roni,
I don't have an error message, and the image is not black, I just get

You say you don't get any error messages, but did you set
OSG_NOTIFY_LEVEL=DEBUG when running your app? Any GLSL compiler
warnings/errors will show up then.
It's not clear to me what you're saying. Are you saying that even when you
specify ON, fog is not enabled? Or are you saying that when you query the
StateSet's GL_FOG mode later, you're not getting what was set? Or are you
saying that when you dump the scene graph out to an .osg file, GL_FOG ON

Hi,
I compiled and installed OpenSceneGraph on Linux successfully. Now I would like
to compile and install osgdem because I would like to load some elevation data
into osg.
I followed the steps which are described on
http://www.openscenegraph.org/projects/osg/wiki/Support/UserGuides/osgdem
I mean that when settings ON on the Fog, then the fog is enabled but when
querying the corresponding RefAttributePair there is no ON. Rather, the
ON ends in the associated mode (GL_FOG only I guess) bit field.
this transfer of the ON from the attribute to the corresponding Mode
surprise me a bit
You might either
* build an osg::HeightField
(http://www.openscenegraph.org/documentation/OpenSceneGraphReferenceDocs/a01227.html)
and draw it with an osgTerrain::TerrainNode node with an
osgTerrain::HeightFieldLayer as an elevation layer
* or use VirtualPlanetBuilder

It sounds like a graphics driver problem of some sort. I have successfully

What OS are you using?

From the generality of your question I would suggest you first go
look at the Virtual Terrain Project web site..
It's an awesome source of info.

Still on the same subject, I've noticed something even more strange (well
maybe that's very well known but I've just discovered it...):

calling stateset-setAttributeAndMode(attribute,ON/OFF)
but, in the case of a

Yes, the function, as it is written, is [min, max]sorry about my typo.
If the intent of this function is, as you say, is [min, max], then the

always assume a get_random is [min, max), which can be used for

Hello everybody,
I believe the get_random() function in range under osgParticle should be:
minimum + (maximum - minimum) * rand() / (RAND_MAX + 1);
It is written as:
minimum + (maximum - minimum) * rand() / RAND_MAX;
If you expect
The comment says between min and max (min x max), but the function will
return (min = x = max)
I'm just trying to clarify the actual intent of this function. Was the
author intending the former, or latter?

Yes sure, I could disable lighting in that simple case (Yet I'm not even

Hi,
As others have mentioned you can bump up the notify level to see the
infologs from the compile and link. There is also a method to directly
query the infolog. The GL2Extensions contain the tests that determine

That said, first thing is to
Not all attributes have modes, as you've discovered with Material. The
current OSG paradigm of being able to setAttributeAndModes for Material
really doesn't make much sense. I'd be reluctant to rewrite any portions of
OSG dealing with the fixed function pipe, though, in light of OpenGL 3.

You could move them to notify level DEBUG_FP; DEBUG uses DEBUG_INFO, so they
