Hi all
I'm moving an app from Producer to osgViewer and have doubts about the
equivalence between some Producer methods vs. osgViewer methods.
May you help me, indicating the methods more suitable to change in the
Producer code fragment below, in order to get it working under
osgViewer?
Thanks,
Bruno
-----------------------------
//variables (just to contextualize)
osgProducer::Viewer* viewer_obj;
Producer::Camera *camera_obj;
int x, y, width, height;
double d_left, d_right, d_bottom, d_top, d_nearClip,
d_farClip, d_xshear, d_yshear;
float f_near, f_far, f_hfov, f_vfov;
osg::Matrix matrix;
osg::Matrixd matrixd;
std::string name = "My Camera";
osg::Group* hud;
//methods that need conversion
viewer_obj->getGlobalStateSet()->setMode( GL_FOG,
osg::StateAttribute::OVERRIDE|osg::StateAttribute::ON );
camera_obj->getLensParams(d_left, d_right, d_bottom,
d_top, d_nearClip, d_farClip, d_xshear, d_yshear);
camera_obj->setLensFrustum( d_left, d_right, d_bottom,
d_top, d_near, d_far, d_xshear, d_yshear );
viewer_obj->getCameraConfig()->addCamera( name, camera_obj );
camera_obj->setProjectionRectangle ( x, y, width, height );
camera_obj->setLensAutoAspect(true);
camera_obj->setLensPerspective( f_hfov, f_vfov, f_near, f_far );
camera_obj = viewer_obj->getCameraConfig()->
findCamera( name.c_str() );
camera_obj->setOffset( matrix.ptr() );
viewer_obj->setSceneDecorator( hud );
viewer_obj->setViewByMatrix( Producer::Matrix( matrixd.ptr() ) );
viewer_obj->update();
camera_obj->frame( false );
osgDB::Registry::instance()->getOrCreateDatabasePager()-
>setUseFrameBlock(true);
for(SceneHandlerList::iterator itr = viewer_obj->_shvec.begin();
itr != viewer_obj->_shvec.end(); ++itr)
{
osgDB::Registry::instance()->getOrCreateDatabasePager()->
setCompileGLObjectsForContextID(
(*itr)->getSceneView()->getState()->getContextID(), false );
}
