How to implement AutoCAD highlight effect?

HOOPS Visualize
1

When I select an entity in AutoCAD, the selected entity is expressed in an offset shape and fluorescent color around the entity. I wonder if there is a way to create this selection effect. How can I create the AutoCAD selection effect?

Hello Mini,

Are you using HOOPS HPS or HOOPS 3DF API?

We do not have the halo highlight effect your looking for but I might be able get something closer.

Hello Mini,

Here is sample code in HPS.

	HPS::PortfolioKey myPortfolio = GetCanvas().GetFrontView().GetPortfolioKey();

    HPS::NamedStyleDefinition halo_style = myPortfolio.DefineNamedStyle("green halo", HPS::Database::CreateRootSegment());
	halo_style.GetSource().GetVisibilityControl().SetFaces(false).SetEdges(true).SetLights(false);
	halo_style.GetSource().GetMaterialMappingControl().SetEdgeColor(RGBColor(0.0f, 1.0f, 0.0f));
	halo_style.GetSource().GetDrawingAttributeControl().SetDepthRange(0.9f, 1.0f);
	halo_style.GetSource().GetEdgeAttributeControl().SetWeight(20.0);
    GetCanvas().GetFrontView().GetSegmentKey().GetPortfolioControl().Push(myPortfolio);




	HPS::WindowKey myWindowKey = GetCanvas().GetWindowKey();

    HPS::SelectionOptionsKit selectionOptions;
    selectionOptions.SetAlgorithm(HPS::Selection::Algorithm::Analytic);
    selectionOptions.SetLevel(HPS::Selection::Level::Entity);


    // the origin will be the selection point
    HPS::Point selectionPoint(0, 0, 0);

    HPS::SelectionResults selectionResults;
    size_t numSelectedItems = myWindowKey.GetSelectionControl()
					.SelectByArea(HPS::Rectangle(-1, 1, -1, 1), selectionOptions, selectionResults);


    HighlightOptionsKit hok;
    hok.SetStyleName("green halo");

	myWindowKey.GetHighlightControl().Highlight(selectionResults, hok);

	GetCanvas().UpdateWithNotifier().Wait();

Let us know if you have any other questions.
