Dear Arefin and Patrick,
Thanks Patrick for the help! It got me started.
But I think my code does not go into the functions inside
igstkNDITracker.cxx.
I included the last the line, 241 at igstkNDITracker.cxx
const unsigned long mflags = (CommandInterpreterType::NDI_TOOL_IN_PORT |
CommandInterpreterType::NDI_INITIALIZED |
CommandInterpreterType::NDI_ENABLED |
CommandInterpreterType::NDI_OUT_OF_VOLUME);
and added this at line 272
if (m_ToolStatusContainer[inputItr->first] ==
CommandInterpreterType::NDI_OUT_OF_VOLUME)
{
igstkLogMacro(DEBUG, "igstk::NDITracker::InternalUpdateStatus: "<<
"tool" << inputItr->first <<" is out of volume\n");
this->ReportTrackingToolVisible(
trackerToolContainer[inputItr->first] );
cout<<"NDI TRACKER OUT OF VOLUME \n;
}
and I changed line 356 :
m_CommandInterpreter->TX(CommandInterpreterType::NDI_XFORMS_AND_STATUS
to
m_CommandInterpreter->TX(CommandInterpreterType::NDI_INCLUDE_OUT_OF_VOLUME);
Hmm...
But Nothing prints out.
I really appreciate your help, but could you help me out one more time?
The event doesn't seem to run. Perhaps I should change igstkTracker class?
I assumed that when I run polarisExample (which is similar to how I coded),
the events go through igstkNDITracker.cxx.
How can I get the *position* out from MISSING of Out Of Volume status?
And I am also wondering if calling TX is right thing to do.. Maybe,
i should call BX(int mode) instead?
Thanks so much.
Sincerely,
Jamie.
