[osg-users] ConvexHull

[Nitin Rangari]

I have created class AXConvexHull derive from  osg::TriangleMesh

class AXConvexHull:public osg::TriangleMesh
{
public:

public:

        AXConvexHull() {}

       /* AXConvexHull(const AXConvexHull& mesh,const CopyOp&
copyop=CopyOp::SHALLOW_COPY):
            Shape(mesh,copyop),
            _vertices(mesh._vertices),
            _indices(mesh._indices) {}
        META_Shape(osg, AXConvexHull);*/


void setVertices(osg::Vec3Array* vertices) { _vertices = vertices; }
         osg::Vec3Array* getVertices() { return _vertices.get(); }
        const osg::Vec3Array* getVertices() const { return _vertices.get();
}

void setIndices(osg::IndexArray* indices) { _indices = indices; }
osg::IndexArray* getIndices() { return _indices.get(); }
const osg::IndexArray* getIndices() const { return _indices.get(); }

void setNormals(osg::Vec3Array* normals) { _normals = normals; }
osg::Vec3Array* getNormals() { return _normals.get(); }

    protected:

virtual ~AXConvexHull(){}
osg::ref_ptr<osg::Vec3Array> _vertices;
osg::ref_ptr<osg::IndexArray> _indices;
osg::ref_ptr<osg::Vec3Array> _normals;
};

but when i do

            osg::ref_ptr<osg::Geode> geode=new osg::Geode();
 adaptive3d::AXGraphicsMesh* patch =dynamic_cast<AXGraphicsMesh*>(gObject);
if(patch!=NULL)
{
 myMesh->setIndices(patch->getIndicesData());
myMesh->setVertices(patch->getVerticesData());
myMesh->setNormals(patch->getNormalData());
                }
           currentShapeDrawable = new osg::ShapeDrawable(myMesh);
 geode->addDrawable(currentShapeDrawable);
rootgNode->addChild(geode.get());
its not showing anything
.
