Re: [osg-users] Jean-Sebastien Guay,kim in osgOCean application
hi,Jean-Sebastien Guay,kim and others: sorry,we are in different time zones,it is difficult for me to keep online in touch with you. As you said ,i disable full screen and glare effect,and load spaceship.osg in osgOcean application.The transparent flame trail of spaceship is rendered correctly,but the color of transparent flame trail is not colorful ,just grey or white(highlight).I adjust the scene light source parameters,but have no effect.Do you solve the problem in your lab ? Can you post me codes explaining the solutions? regards, houxl. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] re :transparent objects render in osgOcean
hi,kim ,Jean-Sebastien Guay and others: I have registered an account in forem,but the messages i sent is awaiting approval.So i post my reply by mailing list. in osgocean example ,i disable glare and dof false in ocean scene initialization. ... _oceanScene-enableUnderwaterDOF(false); _oceanScene-enableGlare(false); ... then,i print screen and get some images which are in email attachments. (1)render correctly no ocean.JPG the image is rendered in osgviererMFC.the flame trail is colorful. (2)(application init) disable glare and dof(underwater).JPG in osgocean example initialization: _oceanScene-enableUnderwaterDOF(false); _oceanScene-enableGlare(false); after initialization,i don't press usful key to change effects. (3)(run-time )disable glare and dof(underwater).JPG at run-time,i press key to toggle glare and dof(underwater) false. From the three images you maybe know what happen in spaceship flame trail.In fact ,i want to get the reason why the flame trail turns grey or white when i toggle glare and dof(underwater) false at run time.If you have solutions ,please send me codes explaining it. Thank you!

[osg-users] osgOcean application
Hi ,all:
In the ocean example attached osgOcean,i loaded a 3d model which is named
spaceship.osg from osg offical data, but i did not find the transparent
colorful flame trail of spaceship,which exist in fact if spaceship was rendered
correctly . why?
the code as follows:
//==
...
osg::ref_ptrosg::Node loadedModel = osgDB::readNodeFiles(arguments);
// any option left unread are converted into errors to write out later.
arguments.reportRemainingOptionsAsUnrecognized();
// report any errors if they have occurred when parsing the program
arguments.
if (arguments.errors())
{
arguments.writeErrorMessages(std::cout);
return 1;
}
osgViewer::Viewer viewer;
viewer.setUpViewInWindow( 150,150,1024,768, 0 );
viewer.addEventHandler( new osgViewer::StatsHandler );
osg::ref_ptrTextHUD hud = new TextHUD;
osg::ref_ptrSceneModel scene = new SceneModel(windDirection, windSpeed,
depth, scale, isChoppy, choppyFactor, crestFoamHeight);
viewer.addEventHandler(scene-getOceanSceneEventHandler());
viewer.addEventHandler(scene-getOceanSurface()-getEventHandler());
viewer.addEventHandler( new SceneEventHandler(scene.get(), hud.get(),
viewer ) );
viewer.addEventHandler( new osgViewer::HelpHandler );
osg::Group* root = new osg::Group;
root-addChild( scene-getScene() );
root-addChild( hud-getHudCamera() );
if (loadedModel.valid())
{
loadedModel-setNodeMask( scene-getOceanScene()-getNormalSceneMask()
|
scene-getOceanScene()-getReflectedSceneMask()
|
scene-getOceanScene()-getRefractedSceneMask()
);
scene-getOceanScene()-addChild(loadedModel.get());
}
// load spaceship ,added by me
osg::ref_ptrosg::PositionAttitudeTransform pat = new
osg::PositionAttitudeTransform();
//osg::Vec3(10.0f,0.0f,0.0f)
pat-setPosition(osg::Vec3(0.0f,0.0f,20.0f));
osg::ref_ptrosg::Node spaceship= osgDB::readNodeFiles(spaceship.osg);
if (spaceship.valid())
{
spaceship-setNodeMask( scene-getOceanScene()-getNormalSceneMask() |
scene-getOceanScene()-getReflectedSceneMask()
|
scene-getOceanScene()-getRefractedSceneMask()
);
pat-addChild(spaceship.get());
scene-getOceanScene()-addChild(pat.get());
}
viewer.setSceneData( root );
viewer.realize();
while(!viewer.done())
{
viewer.frame();
}
return 0;___

[osg-users] re :Kim and Jean-Sebastien Guay in osgOcean application(render transparent objects)
Hi,Kim and Jean-Sebastien Guay thank your good advice! I am very interested in ocean water rendering, osgOcean is a very good module of osg.But i think that some functionality is added in osgOcean. as follows: 1)as kim said,add another transparency processing pass,and make osgocean render transparent objects well. I hope that kim will add transparency processing functionality soon. If added,please send message to me. 2)according to longitude, latitude,date and time,simulate skydome,skylight and daylight,and render ocean water at any time(for example sunrise,sunset water ) 3)avoid tile repeat of ocean scene (for example ,two bands samples for ocean spectrum ) I want to join in development of osgOcean ,and hope kim and Jean-Sebastien Guay to help me solve some problems. regards, houxl(osghxl).___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
