<div dir="ltr">vtkPropPicker doesn't have this functionnality but you can use another classe: vtkVisibleCellSelector. It is the same algorithm behind but it permits to render a window of your scene for picking and all objects pickable that will be rendered in this window will be selected. So to make a tolerance you can render a window of 5x5 pixels under the mouse position and it will select your line if it is in this area.<br>

<p>Hi everyone,</p>
<p>I need vtkPropPicker for picking an actor which created from
vtkLineSource. Other pickers are too slow and do not satisfy user requirements.
vtkPropPicker is extremely fast but its tolerance is not enough, picking the
lines in a scene requires really good mouse skill and patience :D. I couldn't
find a setTolerance function as such in vtkPicker… Is there another way
to adjust picking tolerance in vtkPropPicker? </p>
<p>Thanks already…</p>
