<div dir="ltr">Hello !<br>Sorry for posting one more time, please ignore the previous message:<br><br>I have a VTK question that has cost me time <br>and a lot of hair ;)<br><br>I am defining poly data, a mapper and an actor.<br>
Now, when I change the underlying poly-Data, the graphical representation <br>
does not change :<br><br>----------------------------------------------------------------------<br><br>vtkPoints* l_pts = vtkPoints::New();<br><br> l_pts->InsertPoint(0,0.0,0.0,-1.0);<br><div dir="ltr"> l_pts->InsertPoint(1,0.0,0.0,-1.0);<br>
l_pts->InsertPoint(2,0.0,0.0,-1.0);<br> l_pts->InsertPoint(3,0.0,0.0,-1.0);<br>
<br> vtkCellArray* l_cells = vtkCellArray::New();<br><br> l_cells->InsertNextCell(4); <br> l_cells->InsertCellPoint(0);<br> l_cells->InsertCellPoint(1);<br> l_cells->InsertCellPoint(2);<br> l_cells->InsertCellPoint(3);<br>
<br> m_polydata->SetPoints(l_pts);<br> m_polydata->SetPolys(l_cells);<br><br> CDataSpace* l_space = l_prop->GetBox().get();<br> m_polydata->GetPoints()->SetPoint(0,l_space->x_min,l_space->y_min,-1.0);<br>
m_polydata->GetPoints()->SetPoint(1,l_space->x_min,l_space->y_max,-1.0);<br> m_polydata->GetPoints()->SetPoint(2,l_space->x_max,l_space->y_max,-1.0);<br> m_polydata->GetPoints()->SetPoint(3,l_space->x_max,l_space->y_min,-1.0);<br>
<br><br>
m_polydata->Update();<br> m_mapper->Update();<br><br>
----------------------------------------------------------------------<br><br>The first time I am doing this works, but when i change the points using <br>getPoint()->setPoint(....) again, nothing happens. <br><br>regards, Oliver<br>
