[vtkusers] Showing vtkAxesActor near the bottom left corner of a render window

[Dean Inglis]

Hi Prashanth:

 

try this code:

 

 

  this->AxesActor = vtkAxesActor::New();

  this->AxesActor->SetShaftTypeToCylinder();

  this->AxesActor->SetXAxisLabelText( "X" );

  this->AxesActor->SetYAxisLabelText( "Y" );

  this->AxesActor->SetZAxisLabelText( "Z" );

  this->AxesActor->SetTotalLength( 1.5, 1.5, 1.5 );

 

  this->AxesWidget = vtkOrientationMarkerWidget::New();

  // place at lower left corner

  this->AxesWidget->SetViewport( 0.0, 0.0, 0.25, 0.25 );

  this->AxesWidget->SetOrientationMarker( this->AxesActor );

  this->AxesWidget->KeyPressActivationOff();

Hi All,
 
How can I show a vtkAxesActor near the bottom left corner of the
render window at all the times? I mean irrespective of the camera
position/orientation/dolly, I would like the axes actor to always be
visible at the bottom left corner of the render window and its size
must never change.
 
Also, I have been trying hard to show axis labels, but it just doesnt
show up :-(.
 
Please help.
 
Thanks,
Prashanth
