Re: [osg-users] osgOcean application
Hi,kim ,Jean-Sebastien Guay and others:
I tried it as you said ,and disabled the default shader (which is enabled by
default in oceanscene).
void OceanScene::setUseDefaultSceneShader( bool enable )
{
_enableDefaultShader = enable;
}
I also loaded the cessnafire.osg in osgOcean example,But it had no effect, it
didn't completely solve the transparent object rendering.
Kim ,you are the developer of osgOcean .I am sure that you will solve it.
And ,now,I am studying the source code in order to solve it.
Thank you!
Cheers,
Hou

Re: [osg-users] osgOcean application
Hi,kim I print screen and get some images.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.

Hi Houxl,
Try disabling the default shader (which is enabled by default in oceanscene)
void OceanScene::setUseDefaultSceneShader( bool enable )
{
_enableDefaultShader = enable;
}

[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;___

The default scene shader in osgOcean is very simple and is missing lots
of things, most models will not render properly using it. You need to
replace the shader with your own.
See resources/shaders/default_scene.{vert|frag} for guidance as to which
uniform variables to use for various effects like fog and such. They are
prefixed with osgOcean_. You can even use those shaders as a base and
just modify them. Then call
oceanScene-setDefaultSceneShader(osg::Program*) loading your modified
shaders in the osg::Program you pass to the function.
Hope this helps,
J-S

Re: [osg-users] osgOcean application
Just a little more information on this one. If you wish to use
transparency in conjunction with osgOcean you will have to disable the
full screen effects (depth of field and cross hatch glare) as they
overwrite the alpha channel of objects rendered within the scene. In
order to use these effects at the same time as transparency you'll
have to add another render pass for transparent objects and then
combine it into the scene. If you want to add that functionality i'd
be happy to add it...
Regards,
Kim.
