<DIV><FONT face=Arial size=2>Hello,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>this is what i am currently doing. I have created
an application in C++ where i render a DICOM dataset. I also have some text
files and each one contains a set of coordinates that form a polygon.
With the rendered volume i also render the polygons (vtkActor). What i want to
do is add to the application the functionality of selecting these
polygons-actors. For example the user moves the mouse pointer on top of a
polygon. He then presses "p" or another button, and the actor is picked so he
can view the polygon's surface area.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>If anyone has an example in C++ that does more or
less what i wanna do or can give me some tips i would be really grateful since i
need to do this asap and have no experience at all in observers, pickers, events
etc!!!!</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Thanks in advance</FONT></DIV>
