display the number of every node

[panagiotis]

hi!

i want to display the number of every node in a 3d surfaceplot
i add the data with loadFromData(Qwt3D::TripleField,Qwt3D::CellField );
but i only get the lines(edges) in 3dspace

how can i display also a number for every node??

the code that i use is

PlotWindow3D::PlotWindow3D(QWidget *parent, PTModel *ptm)

QWidget(parent)
{
ui.setupUi(this);

Qwt3D::SurfacePlot *sp = new Qwt3D::SurfacePlot(this);
ui.verticalLayout->addWidget(sp);

sp->setPlotStyle(Qwt3D::WIREFRAME);

//do blue….
Qwt3D::RGBA rgba;
rgba.r = 0.0;
rgba.g = 0.0;
rgba.b = 1.0;
sp->setMeshColor(rgba);

Qwt3D::TripleField tf;
Qwt3D::CellField cf;
Qwt3D::Cell c1;

tf.clear();
cf.clear();
c1.clear();

const QModelIndex mi;
dvector dvx = ptm->getColumn("x");
dvector dvy = ptm->getColumn("y");
dvector dvz = ptm->getColumn("z");
for (unsigned i = 0; i < dvx.size(); i++) {
tf.push_back(Qwt3D::Triple(dvx_, dvy, dvz));
c1.push_back(i);
}
cf.push_back(c1);

sp->loadFromData(tf, cf);

sp->setRotation(30,0,15);
sp->setShift(0.15,0,0);
sp->coordinates()->axes.setLabelString("x-axis");
sp->coordinates()->axes.setLabelString("y-axis");
sp->coordinates()->axes.setLabelString("z-axis");

sp->setMeshLineWidth(2);

sp->setCoordinateStyle(Qwt3D::FRAME);

sp->updateData();
sp->updateGL();

}
