3D scene: How to apply height to a Graphic/PictureMarkerSymbol

Question

I use a map (3D) and a scene (3D)

To display an object i use the PictureMarkerSymbol and assign an image to it.

By applying the geometry i can place the object on the map - fine.

But in the 3d context i would like to apply the z-value to the geometry/object too.

How can i do this?

The DictionaryRenderer displays a line to the bottom (using alternating colors)

I would like to consider this as a next step - if possible.

Any hints?

Thanks in advance

Hi Norbert, for this you would need to make use of the surfacePlacement methods on LayerSceneProperties. For example, the code below places a picture marker symbol at a height of 1000m above Edinburgh:

PictureMarkerSymbol* pms = new PictureMarkerSymbol(myImageUrl, this);

Graphic* g = new Graphic(Point(-3.1883, 55.9533, 1000., SpatialReference::wgs84()), pms, this);

overlay->graphics()->append(g);

LayerSceneProperties sceneProps = overlay->sceneProperties();

sceneProps.setSurfacePlacement(SurfacePlacement::Relative);

overlay->setSceneProperties(sceneProps);

Note that the sceneProps are returned by value not by reference so you need to set them back onto the overlay.

Hope that helps,

Luke
