<p>Hi everyone;<o:p></o:p></p>
<p>I am trying to get the points where user clicks and drags the mouse and
create shapes by using these points. I've written a class that looks like
wxVTKRenderWindowInteractor which doesn't handle interaction but shows vtk
scene in wxWindow. When user selects one of the toggle toolbar buttons (for
drawing line, angle, rectangle etc.) mouse events are sent to a class named
GlassPanel that handles all drawing stuff. When user clicks a point, that point
is taken as p1, and when user starts dragging the mouse , position of mouse is
taken as p2, depending on what shape is selected a shape must be created by
using these two points. Firstly I decided to use vtkLineWidget for drawing
lines but I couldn't manage it, because wxWidgets coordinate system's origin is
upper left hand corner, and vtk uses lower left hand corner as origin. I tried
to convert wxWidgets event coordinates to vtkCoordinate system, but I even
couldn't find which coordinate system is used by vtkRenderer. Wherever i click
on wxWindow lines are drawn at the windows center. How should I convert these
coordinates?Or what is the best way to draw 2D shapes using vtk?<o:p></o:p></p>
<p>Thanks already…<o:p></o:p></p>
