Re: [osg-users] CompositeViewer multiple windows, same scene problem
Hi Alvaro, I just did a quick test under Windows 7, with OSG 3.0.1 and Qt 4.8.2. Two views (created from GraphicsWindowQt) of a CompositeViewer in two windows can render the same node (lz.osg for my case) smoothly. Could you please provide more information about your implementation? If you are going to render textures of view 1 directly in view 2, maybe you have to enable OpenGL's shared context feature. You may specify camera 1's graphics context to Traits::sharedContext in such case. Wang Rui 2012/10/4 Alvaro Segura aseg...@vicomtech.org: Hi, We are having trouble using a CompositeViewer with 2 views in 2 windows, showing the same scene (same Node*). The first view (in addView order) is rendered correctly, but the second view is badly rendered with some missing or garbled geometries. If only one view is added, its rendering is fine. If instead of 2 windows, we use only one window with two contiguous viewports, rendering is fine. Each view has its own Camera and GraphicsContext. We use GraphicsWindowQt with or without the shareWidget argument. Using setUpViewInWindow() instead does the same. Seems that the first render is misusing the GL context or something so that the other has trouble. Threading is set to SingleThreaded to avoid potential sharing problems (but the TaskManager is showing many running threads (?)). The problematic models are FBX exported from 3ds Max, BTW. Is there any setting that has to be set in OSG/CompositeViewer to tell it that the scene is shared? Does anyone have an idea what can be wrong in such a setup? Thank you!

Re: [osg-users] Memory issues when using uniform shader variables on Intel HD graphics
Hi
What exactly makes memory usage increase? What if you attach shader without
uniform, or without adding uniform to stateset? Try to add #version 110
directive as first line of your shaders, does it make any difference?
I think you'd better send bugreport to intel, best if you can reproduce this
with pure opengl.

Hi,
I'm trying to use shaders on an Intel HD 3000 graphics chip (Windows7 x64,
latest graphics driver).
As soon as I pass a uniform variable to the shader (regardless of the type),
the memory of my process increases by about 400MB. Other than that, the
shader works fine.
The size of the object the shader is attached to or the complexity of the
shader do not make a difference. Every additional shader (containing at least
one uniform variable) I use, increases the memory usage by another 400MB.
The problem does not occur on another machine with some NVidia graphics card.
Has anyone encountered a similar problem or does someone have an idea what
could cause a problem like this?
Code:
osg::Program *program = new osg::Program;
osg::Shader *frag = new osg::Shader( osg::Shader::FRAGMENT, fragSource.str()
);
osg::Shader *vert = new osg::Shader( osg::Shader::VERTEX, vertSource.str() );
program-addShader( frag );
program-addShader( vert );
// add shader to stateSet
sset-setAttributeAndModes( program, osg::StateAttribute::ON );
// add uniform variable
osg::Uniform *var = new osg::Uniform(MATERIAL_COLOR,
osg::Vec4(1.0f,1.0f,0.0f,1.0f));
sset-addUniform(var);
Code:
// Vertex Shader
void main()
{
gl_Position = ftransform();
gl_ClipVertex = gl_ModelViewMatrix * gl_Vertex;
}
// Fragment Shader
uniform vec4 MATERIAL_COLOR;
void main()
{
gl_FragColor = MATERIAL_COLOR;
}
By the way, I know I'm not using reference pointers :? but this shouldn't be
a problem in this little example.
...
Thank you!

Re: [osg-users] multipass transparency
Hi
If you need to blend all visible layers - try to change order of passes, and
set colormask to all false's (so first will be only color, second only depth).
If you dont need depth from transparent geometry - you can get by with only
first pass.
If you need only closest single layer - you draw first pass depth only (with
colormask set to false's), second pass with depth test set to lequal.
Cheers.

Getting models into your application will likely be one of the biggest challenges. There is a good chance the models will contain parametric data, if so you'll need to consider how to tessellate the parametric surfaces into triangle meshes so that they can be rendered by the graphics hardware. You can tessellate data on the CPU and this in the past was traditional way to do it, but these days the GPU should be able to take on some of this work. This area is a big topic. As for performance optimization, the OSG has lots of support for various features for getting the best performance out of scene graph, but in the end it's how you construct your scene graph that will determine how well it will perform. Performance optimization is another huge topic that I can't sumerise in book let alone a single email so I would suggest breaking the task down it smaller elements that focus on your specific needs and ask specific questions here in the community and we'll have a better chance of answering them. So take a step back, tell us what type of data you have to work with, what number of objects is likely to be, how complex in geometry are these objects likely to be, do you have meshes or parametric surfaces etc. Robert. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

[osg-users] Normalmap with osgPPU
Hello.
Is it possible to retrieve the normal map using osgPPU ?
I have used the following shaders and a blue screen appears.
Vert
---
varying vec3 normal;
void main(void){
gl_Position = ftransform();
normal = gl_NormalMatrix * gl_Normal;
}
Frag
---
varying vec3 normal;
void main(){
gl_FragColor = vec4(normal,1);
}
I guess the blue color means that the normal.z is always 1.
In some examples in osgPPU solution, i have noticed that vertex shaders are
used.
Which vertices are passed through these shaders ? All of the scene's
vertices or just the ones that are visible ?

Before you enter the render loop (i.e. viewer.run()), do the following to configure and set the initial position of your ownship using lat, lon, altitude with a heading, pitch, roll of 0.0... view-setCameraManipulator(new osgGA::FlightManipulator()); osg::Matrixd position; earth-computeLocalToWorldTransformFromLatLongHeight( osg::DegreesToRadians(lat), osg::DegreesToRadians(lon), altitude, position); osg::Matrixd rotation2YUp; rotation2YUp.makeRotate(M_PI_2, osg::Vec3d(1.0, 0.0, 0.0)); position = rotation2YUp * position; view-getCameraManipulator()-setByMatrix(position); After you do this, the Flight Manipulator will move your ownship along like usual. If you need to extract positional info from the manipulator, you can get it from the ownship update callback. For example, in your callback, you can extract out the ownship position in geocentric coordinates from the flight manipulator by doing the following... osg::Vec3d geocentric_eye = view-getCamera()-getInverseViewMatrix().getTrans(); Hope this helps...

ss-setAttributeAndModes( new osg::ColorMask(true, true, true, true) );
osg::Depth* depth = new osg::Depth;

false, false) );
depth-setWriteMask( true );
ss-setAttributeAndModes( depth, osg::StateAttribute::ON );

}
However, it could not handle sel-intersection(the picture in the attached doc)
Using:
transparency-setRenderingHint(osg::StateSet::TRANSPARENT_BIN);
transparency-setAttributeAndModes(new osg::BlendFunc(GL_SRC_ALPHA
,GL_ONE_MINUS_SRC_ALPHA), osg::StateAttribute:ShockedN);
osg::Depth* depth = new osg::Depth;
depth-setWriteMask( false );
transparency-setAttributeAndModes( depth, osg::StateAttribute::ON );
_geom_solid-setStateSet(transparency);
instead of
transparency-setRenderingHint(osg::StateSet::TRANSPARENT_BIN);
transparency-setAttributeAndModes(new osg::BlendFunc(GL_SRC_ALPHA
,GL_ONE_MINUS_SRC_ALPHA), osg::StateAttribute:ShockedN);
_geom_solid-setStateSet(transparency);
self-intersection is correct. However, some transparent parts will disappear,
like the wheels of the car in the picture in the doc, the color seems to be
blended after the inner parts.
