The Axis Triad and Navication Navigation Cube assist the user with scene orientation. Both may be enabled and customized using the appropriate control;

...

Using the hps_mfc_sandbox project, add the following function to CHPSView.cpp;

Code Block

void DoSetAxisText(HPS::SegmentKey seg, const char* text)
{
	HPS::SearchResults result;
	if (seg.Find(Search::Type::Text, Search::Space::Subsegments, result) > 0)
	{
		HPS::SearchResultsIterator it = result.GetIterator();
		while (it.IsValid())
		{
			HPS::Key key = it.GetItem();
			if (key.Type() == HPS::Type::TextKey)
			{
				HPS::TextKey sKey = (TextKey)key;
				// set other text properties e.g. sKey.SetSize(16, HPS::Text::SizeUnits::Pixels);
				sKey.SetText(text);
			}
			it.Next();
		}
	}
}

Next add the following to the User Code 3 method of the CHPSView class;

Code Block

void CHPSView::OnUserCode3()
{
	_canvas.GetFrontView().GetAxisTriadControl().SetVisibility(true).SetLocation(HPS::AxisTriadControl::Location::BottomLeft);
	_canvas.GetFrontView().GetNavigationCubeControl().SetInteractivity(true);
}

Additionally, add the following to the User Code 4 method of the CHPSView class;

Code Block

void CHPSView::OnUserCode4()
{
	SegmentKey viewSegKey = GetCanvas().GetFrontView().GetSegmentKey();

	if (viewSegKey.Type() != HPS::Type::None)
	{
		SearchResults searchResults;
		size_t numResults = viewSegKey.Find(Search::Type::Segment, Search::Space::SubsegmentsAndIncludes, searchResults);
		if (numResults > 0)
		{
			SearchResultsIterator it = searchResults.GetIterator();
			while (it.IsValid())
			{
				Key key = it.GetItem();
				SegmentKey segKey(key);
				if (segKey.Name() == "hps_axis_triad")
				{
					SegmentKey hpsAxisKey = segKey;
					if (hpsAxisKey.Type() != HPS::Type::None)
					{
						SegmentKeyArray sub;
						hpsAxisKey.ShowSubsegments(sub);

						for (size_t i = 0; i < sub.size(); i++)
						{
							HPS::SegmentKey sk = sub.at(i);
							HPS::UTF8 s = sk.Name();

							if (s == "x") //X-Axis
							{
								DoSetAxisText(sk, "A");
							}
							else if (s == "y") //Y-Axis
							{
								DoSetAxisText(sk, "B");
							}
							else if (s == "z") //Z-Axis
							{
								DoSetAxisText(sk, "C");
							}
						}

					}
				}
				it.Next();
			}
		}
	}
	GetCanvas().UpdateWithNotifier().Wait();
}

Info
Keep in mind this approach relies on several internal HOOPS implementation details (e.g. segment key name "hps_axis_triad") which may change.
