Hi All ,
I am trying to place some characters (cal3D) on a terrain I created
using VPB at a particular location on the terrain using the code shown
below. But when i run my program i do not see any thing,  using mouse
(trackball) functionality i cam locate the terrain but could not locate
the model. Can some one tell me what am i doing wrong. I am using latest
version of osgCal2 (checked out from svn ) and OSG 2.0.

int main(int argc, char** argv)
    if (argc < 2)
        std::cout << "specify cal3D cfg file for loading a model " <<
        return 1;

    // Create and setup core model
    osg::ref_ptr< osgCal::CoreModel > coreModel( new osgCal::CoreModel() );
    osg::ref_ptr< osgCal::BasicMeshAdder > meshAdder( new
osgCal::DefaultMeshAdder );
    osg::ref_ptr< osgCal::MeshParameters > p( new osgCal::MeshParameters );
    p->software = true;

    // Load core model from file

    // Create Model
    osgCal::Model* model = new osgCal::Model();

    // Load model
    model->load(coreModel.get(), meshAdder.get());   

    // Create a root node for the scene graph
    osg::Group* root = new osg::Group;

    // Load terrain from the file
    osg::Node* terrainNode = osgDB::readNodeFile("oahu.osga");

    // Add terrain to the scene

    // Choose a location on a terrain to place the model
    osg::Vec3  newPos(2356473.250, 611159.125, 1.515);

    // Create a position attitude transform node
    osg::PositionAttitudeTransform* pat =  new
    // Set position

    // Add character model to the pat

    // Add pat to the scene

    // Setup viewer
    osgViewer::Viewer viewer;

    // Set scene data

    return 0;
