Hi,
i want to auto generate a few LODs with osg::Simplifier
then i want to add these nodes to an LOD
whats going wrong
i see only the first Node from 0 - 300 pixels distance
iam using Version 2.8.2 of OSG
Code:
int main( int argc, char **argv )
{
glutInit(&argc, argv);
glutInitDisplayMode( GLUT_DOUBLE | GLUT_RGBA | GLUT_DEPTH | GLUT_ALPHA );
glutInitWindowPosition( 100, 100 );
glutInitWindowSize( 800, 600 );
glutCreateWindow( argv[0] );
glutDisplayFunc( display );
glutReshapeFunc( reshape );
glutMouseFunc( mousebutton );
glutMotionFunc( mousemove );
glutPassiveMotionFunc( passivemousemove );
glutKeyboardFunc( keyboard );
osg::ref_ptr<osg::Group> root = new osg::Group;
osg::ref_ptr<osg::Node> loadedModel =
osgDB::readNodeFile("C:\\3001.ive");
osg::ref_ptr<osg::LOD> pLod = new osg::LOD ;
pLod->setRangeMode( osg::LOD::DISTANCE_FROM_EYE_POINT );
float sampleRatio = 0.5f;
float maxError = 4.0f;
float multiplier = 0.8f;
float minRatio = 0.001f;
float ratio = sampleRatio;
float LODnear = 0.0;
float LODfar = 300.0;
for ( int i = 0 ; i < 3; i++)
{
ratio *= multiplier;
osgUtil::Simplifier simplifier(ratio, maxError);
osg::ref_ptr<osg::Node> simplNode =
(osg::Node*)loadedModel->clone(osg::CopyOp::DEEP_COPY_ALL);
simplNode->accept(simplifier);
pLod->addChild( simplNode.get(), LODnear, LODfar );
LODnear = LODfar;
LODfar += 300.0;
}
root->addChild( pLod.get() );
viewer = new osgViewer::Viewer;
window = viewer->setUpViewerAsEmbeddedInWindow(100,100,800,600);
viewer->setSceneData( root.get());
viewer->setCameraManipulator( new cSphericalManipulator );
viewer->addEventHandler(new osgViewer::StatsHandler);
viewer->realize();
glutMainLoop();
return 0;
}
Thank you!
Cheers,
Matthias[/code]
