Re: [osg-users] Shadows : Creating multiple osgShadow::ShadowedScene
Let's take an example: ShadowTechnique SHADOWMAP It creates a texture and installs a shader program which makes shadow effects by using the created texture. So what you think happens by the second shadowScene? On traversal it will create a new texture, by default install it in the same texture unit, and install a shader using just this newly created shadow texture. What you expect is a shader program using 2 shadow textures. But this one you have to write yourself. - Werner - On Tuesday 28 September 2010 06:29:50 Saravanan Sivaprahasam wrote: Thanks for the reply.

The tool for the job is a custom NodeVisitor, which does the traversal
of the scene graph for you and then picks out the StateSet's on all
the Node and Drawables. Something like:
class MyFindStateSet : public osg::NodeVisitor
{
public:
std::string _name;
MyFindStateSet(const std::string name):
osg::NodeVisitor(osg::NodeVisitor::TRAVERSE_ALL_CHILDREN),
_name(name) {}
void checkStateSet(const osg::StateSate* stateset)
{
if (node.getStateSet() node.getStateSet()-getName()==_name)
{
// found a node with a the correct stateset, now do what you want...
}
}
void apply(osg::Node node)
{
checkStateSet(node.getStateSet());
// must traverse children otherwise we want descend scene graph
traverse(node);
}
void apply(osg::Geode geode)
{
checkStateSet(geode.getStateSet());
// traverse the drawables of the geode.
for(unsigned int i = 0; igeode.getNumChildren(); ++i)
{
checkStateSet(geode.getDrawable(i)-getStateSet());
}
}
};
..
{
..
// now create the visitor and pass it to the scene graph to do
the traversal
MyFindStateSet mfss(mystateset);
myscenegraph-accept(mffs);
..
}
For further examples of NodeVisitor's in action just do a search of
the OSG code base, you'll find many of them all over the place. It's
one of the most useful classes in the OSG.

Re: [osg-users] osg newbie question: billboard with multiple drawables?

Re: [osg-users] map text to geometry
Hi Katja, osgText uses a texture atlas to store it's glyphs and separate quads to pull out the correct part of the texture atlas to get individual text characters, this makes it impossible to just pull the text texture directly and apply it to an ordinary geometry as the texture coordinates would be all over the place. All is not lost though, the OSG supports render to texture, so it would be possible for you to render a text subgraph and any other geometry you want to a texture and then apply this texture to your geometry. The OSG provides an osgSim::OverlayNode to help make this task even more straight forward as it will manage the render to texture setup for you. See osgsimulation exampe for an example of it in action. Robert.

[osg-users] Problem loading images when migrating to new OSGViewer
Hi,
I've been migrating some code from OSG 0.9.9 to the latest stable release
(2.8.3), and I've run into an issue when migrating from OSGProducer::viewer to
OsgViewer::viewer. I have three models, an airplane.3ds model, a sky.3ds model,
and a globe.osga model. All three models load correctly (the nodes returned
from osgDB::readNodeFile are not NULL), but only the airplane model shows up
when the viewer display is rendered.
The only functions that I needed to change from osgProducer to osgViewer were
my initialization and update functions. I've made sure to replace osgProducer
calls with equivalent osgViewer calls when I upgraded (see code below), but is
there anything I might have missed?
Code:
3DPlaneViewer::Initialize(){
osgViewer::Viewer* viewer = new osgViewer::Viewer();
//scene root
osg::Group* root = new osg::Group();
//load globe and add transform of globe to root group
osg::Node* globeNode = osgDB::readNodeFile(globe.osga);
osg::MatrixTransform* globeTransform = new osg::MatrixTransform();
globeTransform-addChild( globeNode );
//create group for globe and sky
osg::Group*terrainNodes = new Group();
terrainNodes-asGroup()-addChild( globeTransform );
//load airplane
osg::Node* airplaneNode = osgDB::readNodeFile(airplane.3ds);
//specify a location for plane on globe with lat, long, altitude
osg::Matrixd airplaneMatrix;
osg::EllipsoidModel* ellipse-computeLocalToWorldTransformFromLatLongHeight(
osg::DegreesToRadians(20.0f),osg::DegreesToRadians(-30.0f),
15000,airplaneMatrix );
//rotate airplane node
airplaneMatrix.preMult( airplaneMatrix.rotate(
osg::Quat(osg::DegreesToRadians(180.0f), osg::Vec3f( 0, 0, 1 ) )));
//setup matrix wrapper node
osg::MatrixTransform* airplaneTransform = new osg::MatrixTransform();
airplaneTransform-getOrCreateStateSet()-setMode(GL_RESCALE_NORMAL,osg::StateAttribute::ON);
airplaneTransform-setMatrix(airplaneMatrix);
airplaneTransform-addChild( airplaneNode );
terrainNodes-asGroup()-addChild( airplaneTransform );
//load and add the sky model
osg::Node* skyNode = osgDB::readNodeFile(sky.3DS);
osg::MatrixTransform* skyTransform = new osg::MatrixTransform();
skyTransform-addChild( skyNode );
terrainNodes-asGroup()-addChild( skyTransform );
root-addChild( terrainNodes );
//realize the scene in the viewer
viewer-setSceneData(root);
viewer-realize();
}
3DPlaneViewer::Update()
{
//removed calls to osgProducer::sync()
viewer-updateTraversal();
//do some other updates on other objects in the scene
viewer-frame();
}
Thanks,
John

Re: [osg-users] osg newbie question: billboard with multiple drawables?
Hi, on the subject of the autotransform: in scale_to_screen mode, I was trying to use minScale and maxScale to effectively bound the drawn screen size of my geode between a minimum and maximum, but I think I'm mis-interpreting these parameters. Increasing maxScale does not appear to increase the maximum drawn size of my geode, and setting minScale doesn't seem to permit me to define a minimum drawn size? I've had a look at the AutoTransform code and I can see that the application of these scale settings are affected by the transition width, but it's not clear to me how they are connected? If anyone can clarify for me, the relationship between transition width, minScale and maxScale and whether or not these could be used to define a minimum and maximum drawn size of a geode, I'd really appreciate it.

Re: [osg-users] Problem loading images when migrating to new OSGViewer
Hi John,
I don't know the cause of only the airplane showing up, but can
suggest a few things to try to explore what might be going wrong.
First up try loading each of the models with osgviewer and see if each
one loads up OK.
Second write out the completed scene graph to a .osg file just before
you run the viewer code. Then try to load this scene graph into
osgviewer and see what happens.
On the osgProducer::Viewer - osgViewer::Viewer conversion, with
osgViewer the Viewer::frame() method does the sync, update and event
traversals, and the rendering traversals all together. Have a look at
the source code to Viewer::frame() to see what it's doing. You can
break your frame loop out to call each traversals individually if you
want. Have a look at discussions about this on the mailing
lists/forum and the website, and the examples.
In your case you can safely comment out the call to
viewer-updateTravesal() as viewer-frame() will be doing it for you.
Robert.

Hi Adrien, When using multi-texturing you need to decide which texture units to use then set up your texenv (if using fixed function pipeline) or shaders to reflect this. Typically, in your case, one would use texture unit 0 and texture unit 1, so you'd do something like: stateset-setTextureAttribute(0, textureSource); stateset-setTextureAttribute(1, textureLookUp); Robert.

I'm now able to load the image information on a Texture2D and the color table in a Texture1D thanks to the osg::TransferFunction1D class. What I miss now is the link between the two types of texture (Should be there in the same osg::StateSet ? How link the one with the other ?) I've tried to create two textures in the same stateSet but nothing appears. It will be very helpful if you could say me what I'm missing ?

Re: [osg-users] osgart 2.0 with osg2.9.8 video blinking
Hi Huan i compiled osgart 2.0 RC3 with osg2.9.8, when running the video screen was blinking, but before that i used osgart with osg2.8.3 ?everything all right, does anyone meet the same problem? i use win7 64bit and vs2008 compile 32bit osg Are you using texture 2d for your video streams, if so your'e having the same problem as myself, Search the mailing list for 'Texture2D subload callback gone mad' It's an issue with the texture object manager assigning a new texture object every frame. I've sent an example showing the issue to Robert so hopefully he's aware of the issue and can fix it soon. If you use texture rectangles you won't have an issue as they don't require a sub load callback Tom ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

[osg-users] [3rdparty] OSG and SDL
Hi, I am using SDL to get input from a joystick so that I can integrate joystick control in OSG (I have tried the VRPN approach and right now SDL is looking better for my needs). I have searched for as much information about integrating OSG and SDL as possible, and so far it appears that I must use SDL windows and have OSG draw to SDL windows, instead of OSG using its own windowing system. Does anyone know if this assertion is accurate? Is there any way to connect SDL through an OSG Viewer? All I care about are the input events associated with the joystick... Thank you!

Re: [osg-users] Problem loading images when migrating to new OSGViewer
Robert, Thank you for your insight. I did try loading my models with the standalone osgviewer and each of them loaded correctly as did the exported .osg using osgDB::writeNodeFile. I was testing out commenting out different sections, and I noticed that I had this piece of code that I left out in my last post: Code: OsgViewer* viewer = new osgViewer::Viewer(); viewer-getCamera()-setClearColor( osg::Vec4(0.2,0.2,1,1) ); //Replace osgProducer::viewer cull setting with new osgViewer setting //old code: viewer-getCullSettings().setComputeNearFarMode(osgUtil::CullVisitor::DO_NOT_COMPUTE_NEAR_FAR); viewer-getCamera()-setComputeNearFarMode(osgUtil::CullVisitor::DO_NOT_COMPUTE_NEAR_FAR); When I comment out the updated setComputeNearFarMode line of code, my globe and sky models show up correctly but my plane model disappears. Is there a correct cull setting that I should be using to get everything to display? I tried using the COMPUTE_NEAR_FAR_USING_PRIMITIVES and COMPUTE_NEAR_FAR_USING_BOUNDING_VALUES with this call, but I'm not quite sure what bounding value I should be using or if I should be looking at another culling method.

Re: [osg-users] [3rdparty] OSG and SDL
If you just want to use SDL to read joystick inputs, you don't have to use SDL windows. You can use SDL for joystick inputs, and render OGS to windows managed by Qt, CEGUI, or whatever meets your needs. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] [3rdparty] OSG and SDL
Perhaps I just don't know enough about whats going on in my OSG build...but
right now I can just instantiate and start a Viewer in OSG and it automatically
opens a window and handles drawing for me. Is there a way to go about using
OSG this same way but to incorporate SDL?
Right now when I try to grab SDL events while also running an osgViewer, my
main function just exits as if the osgViewer isn't blocking the thread.
My main function has the following code:
Code:
if( SDL_Init(SDL_INIT_JOYSTICK) 0)
{
std::cerr unable to init SDL: SDL_GetError() '\n';
return false;
}else{
std::clog Init'd Joystick :) std::endl;
}
std::atexit(SDL_Quit);
if( SDL_NumJoysticks() == 0 )
{
std::cerr no joysticks found\n;
return false;
}else{
std::clog Found SDL_NumJoysticks() joysticks :)
std::endl std::endl;
for(int i = 0; i SDL_NumJoysticks(); ++i)
{
std::clog Joystick (i + 1) :
SDL_JoystickName(i) std::endl std::endl;
}
}
SDL_Joystick *joystick;
SDL_JoystickEventState(SDL_ENABLE);
joystick = SDL_JoystickOpen(0);
int running = true;
SDL_Event event;
std::clog Left/Right axis: SDL_JoystickGetAxis(joystick, 0)
std::endl;
std::clog Up/Down axis: SDL_JoystickGetAxis(joystick, 1)
std::endl;
// construct the viewer
osg::ref_ptrosgViewer::Viewer viewer = new osgViewer::Viewer;
// make the viewer create a 512x512 window and position it at 32, 32
viewer-setUpViewInWindow( 32, 32, 512, 512 );
// set the scene-graph data the viewer will render
viewer-setSceneData( CreateScene() );
// execute main loop
return viewer-run();
I'm just trying to initialize SDL, grab initial joystick data to prove I am
connected to it, then start the osgViewer. However, the OSG window never pops
up...

Re: [osg-users] IPhone retina displays
Good news on this All seems to be working, I've also improved the IPhoneWindowingSystemInterface to handle true resolutions and multiple screens. So on IPad we should now be able to set a window to an external screen and also change the res of the screen (I don't have an IPad though so needs testing, but should work, gulp :) ) In the end I've gone for the approach of IPhoneWindowingSystemInterface providing the actual pixel res of the screen. Then by default if the user does not set a viewContentScaleFactor in their windowData, the screens scaleFactor is used. This means the default context created by osg viewer will always be full pixel res and the window will be full points res. This was so that I didn't have to create a context of a different size to that requested by default. If the user needs backward compatibility they have to set the traits width and height themselves and set the windowData viewContentScaleFactor to 1.0. I still need to do a bit of testing as I think my objective c code is leaking but I'll get the changes checked in asap. Tom PS The touch coords are returned by the OS in points still so I've converted them to pixels so the current simple example still works as expected. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] [osgPlugins] Missing plugins
