SortingVisual3D

Hi

Is it possible to use ContainerUIElement3D in conjunction with SortingVisual3D?  I would like sorted visuals that have the power of the ContainerUIElement3D class.

Best regards

Simon

Hi Simon! I have not tried this, but I guess it should be possible. Let us know if there is a bug. And remember that the SortingVisual3D is only a 'basic' work-around for the transparency problem...

Hi Objo

Thanks for replying.  I was asking if it is possible as I can't get it to work.  If I add a ModelUIElement3D object as a child of a ContainerUIElement3D object, and add the ContainerUIElement3D object as a child of a SortingVisual3D object, I find that the mouse events are not fired.

e.g.  (geometry code excluded)

var element = new ModelUIElement3D();
element.Model = geometry;
element.MouseDown += this.ContainerElementMouseDown;
var containerUI = new ContainerUIElement3D();
containerUI.Children.Add(element);
var uiTransparentElements = new SortingVisual3D();
uiTransparentElements.Children.Add(containerUI);
viewport.Children.Add(uiTransparentElements);

ok, could changing the base class of HelixToolkit.Wpf.RenderingModelVisual help? Try replace ModelVisual3D by ContainerUIElement3D (I am guessing - no time to test right now).

I did start to try that but unfortunately abandoned as didn't resolve all the build errors.  I will use HitTest workaround for now.  Is it possible to add to future enhancement list?

Thanks, Simon

ContainerUIElement3D is a noniheritable class...

Then try to add a ContainerUIElement3D to the ModelVisual3D.
