Hi Jean,
Yes, I have the local bounding spheres of each of the child nodes. But I'm
still not clear what I need to do to join all the bounding spheres of the child
nodes for the entire model ?
In the code below I'm loading the lwo files and creating local bounding spheres
for each of the components:
Code:
//load the CAD files:
Backhoe = new osg::Group();
Stick = new osg::Node();
Boom = new osg::Node();
Target = new osg::Node();
Bucket = new osg::Node();
Track = new osg::Node();
Cabin = new osg::Node();
LoadBack = new osg::Node();
Stick = osgDB::readNodeFile("_BHStic_.lwo");
Boom = osgDB::readNodeFile("_BHBoom_.lwo");
Target = osgDB::readNodeFile("_BHTarg_.ac");
Bucket = osgDB::readNodeFile("_BHBuck_.lwo");
Track = osgDB::readNodeFile("_BHTrac_.lwo");
Cabin = osgDB::readNodeFile("_BHCabi_.lwo");
LoadBack = osgDB::readNodeFile("_BHLdBk_.lwo");
//bounding spheres:
//initialize here itself (unitialized references cannot exist)
const osg::BoundingSphere& StickSphere = Stick->getBound();
const osg::BoundingSphere& BoomSphere = Boom->getBound();
const osg::BoundingSphere& TargetSphere = Bucket->getBound();
const osg::BoundingSphere& BucketSphere = Cabin->getBound();
const osg::BoundingSphere& TrackSphere = Target->getBound();
const osg::BoundingSphere& CabinSphere = LoadBack->getBound();
const osg::BoundingSphere& LoadBackSphere = Track->getBound();
Thanks,
Sanat
