Re: [osg-users] OSG Animation Tutorial
I don't know if they are tutorails about this, but animation can be done with OSG. To set your animation, you can use blender for example and then, export to osg.

It's a Qt purpose.
To fill the LIBS variable, prefix the paths with -L and the library names with

Re: [osg-users] OSG and QT problem
Hi,
I experiment this. I used an already displayed scene in another viewer. (I
think you do not reload your nodes).
So, they are a marker in the osg::Texture which indicates to unref the image
after apply.
I thinks it a save memory trick.
But in our case, the image does not exist anymore when the scene is set to the
second view.
So, I wrote a visitor which look into each node of my graph and check the
stateset.
I apply it just after loading before insert it in my scene.
So, my code:
// osg::StateSet* stateset = ...
osg::StateAttribute* attribute = NULL;
while( (attribute = stateset-getTextureAttribute(i,
osg::StateAttribute::TEXTURE)) )
{
++i;
osg::Texture* tex = dynamic_castosg::Texture*(attribute);
if( tex )
tex-setUnRefImageDataAfterApply( false );
}
And all should work fine.

Hello,
There is one problem while using OSGViewer in QT:
first run of Widget goes just fine (1.jpg). After I close it and then create it
again there is an incorrect picture (2.jpg).
There is a suspicious chancks in debug info (1.txt and 2.txt):
returning cached instanced of - tells us that an object wasn't
deleted. I closed widget though.
At the first run there are following strings in debug, but they dissapear at
second run:

The following strings appear at the moment when I delete OSGViewer:
Warning: deleting still referenced object 0x6b8d378 of type

the final reference count was 2, memory corruption possible.
OSG 2.8.2.

Where to dig for a solution? Thanx in advance.

[osg-users] Qt4, OSG and HUD
Hi all, Since Qt 4.4, we are able to mix OpenGL and Qt in a way which provides more possibility than the osgViewerQT do by using QGraphics framework, especially for HUD display. I joint the example I write to do this. The main function loads a model a display into my QGraphicsScene inheriting class. On top of it is drawn a simple semi-transparent QWidget but we can draw whatever we want as menu... I extended the example code from the Qt Quaterly to use the osg::Viewer. But I think it can interest other Qt/OSG users. I still have 2 problems I don't have the time to look forward: - The widget transparency only run with the composite viewer (run my example with the --composite argument) - The window resize produces a deformation of widgets inside but I think it more a Qt problem ;) I say this just for information. I hope this could be usefull for someone.

Re: [osg-users] Fog problem
Hi,
Ok, osgprecipitation lz.osg works.
So, I looked into the code and see it set the attribute and mode with the
osg::Fog from the precipitation instead of just enable the GL_FOG mode and let
the precipitationEffect do its work itself.
I correct my program and it run yet! Thanks a lot Robert!
Now, I think it is normal to obtain undefined result if I enable fog without
set the other attributes... But I still ask me why it worked until yesterday,
since I introduced precipitation two weeks ago!

It is very strange, because I don't update my OSG version (which is 2.5.2)

I make a small program to test this out of my other stuff, and test it on
two different machines (both under WinXP, one with an ATI FireGL, the other

Re: [osg-users] Rendering the scene multiple timeswith differentshaders.
I don't know how you perform your multi-pass rendering. But as far I understand the nodeMask, a node is traversed if the logical AND operator between the visitor mask and the node mask is not null. So, if you use two cameras, the first can have a mask to 0x1 to render the subgraph Node_1 and the second camera a mask to 0x2 to render the subgraph Node_4. If the other node has a mask to 0xF, they will be rendered by both cameras. I'm not very good about rendering since my work is more about the generation of scenegraph. So, I hope I don't say wrong. So, the best way is still to test on small example, and osg is good enough to code this kind of small test. Eric Z.

Hi Eric, It looks to me like using the switch could be the solution for my needs. I think that it would either have to be a switch, or a mask. An example of what I want to do could be written like this: Original part of my scene graph: Root | +--Node_1 (Specifies a states and a fragment shader) || |+--Node_2 (Specifies a geometry to be rendered) || |+--Node_3 (Specifies another geometry to be rendered) Using the switch to make sure I can render the scene twice with different shader: Root | +--Switch || |+--Node_1 (Specifies states and a fragment shader) ||| ||+--Node_2 (Specifies a geometry to be rendered) ||| ||+--Node_3 (Specifies another geometry to be rendered) || |+--Node_4 (This is a clone of Node_1 where I have added a new shader) ||| ||+--Node_2 (This is the same node as Node_2 above) ||| ||+--Node_3 (This is the same node as Node_3 above) || Conclusion: - The switch will let one scene render use Node_1 and another scene render use Node_4. Using a mask to achieve the same effect: Root | +--Node_1 (Specifies states and a fragment shader, MASK = 0x1) || |+--Node_2 (Specifies a geometry to be rendered) || |+--Node_3 (Specifies another geometry to be rendered) | +--Node_4 (This is a clone of Node_1 where I have added a new shader, MASK = 0x2) || |+--Node_2 (This is the same node as Node_2 above) || |+--Node_3 (This is the same node as Node_3 above) | Conclusion: - This should work as far as I have understood the mask system, and this time I do not need the switch node. - In this solution I would not need to alter the position of Node_1 in the tree. It is essential for me to have a solution where I do not need to do any work in between each time I render the scene.

One way to do it is to put a shader on the top node and override all child nodes, but that only works if the entire scene-graph renders with the same shader. My scene uses different shaders, so overriding is not the solution. One idea I have is to parse through all scene graphs that I add to my world and duplicate all nodes that sets a fragment shader. I could then create one shader for the normal render and one for the multi target render. This would require that I mask those nodes so that the correct ones are used in each render. This will require me to write my own function for adding nodes to the scene. Anyhow, I would be very happy if someone could guide me in the right direction on this one.
