<html><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; ">Hi,<div> In the following code, I cannot get both vtkActor2D and vtkActor to display simultaneously. If I enable 2D map source and text source, it displays the map and the text. If I enable the 3D cylinder source, the 3D cylinder doesnt get displayed. However, if I disable the 2D map source, the cylinder and the text message appears. </div><div><br></div><div>How can I get the 2D map to display below, and the 3D cylinder to appear to hover above the 2D map ?</div><div><br></div><div>Am I mixing things here? Should I be using vtkImageActor instead of vtkActor2D, so that there is a 3D image plane and then display the 3D source? I really dont want to do that at the moment.</div><div><br></div><div>Please help! :-)</div><div><br></div><div>Best regards,</div><div><br></div><div>Elvis Dowson</div><div><br></div><div><br></div><div><div style="margin-top: 0px;
