... and I think the issue in your original code block is with this segment of the code: QVariantMap att = graphic - > attributes ( ) - > attributesMap ( ) ; att [ QLatin1String ( "height" ) ] = 1000000 ; the QVariantMap is not returned by reference - therefore you need to call graphic->attributes()->setAttributesMap(att); to apply the height attribute to your graphics.

I like to create a cube on a graphicsOverlay in a sceneView (3D) - but without success.
I just can see the plane area drapped on the surface.

I don´t use QML but widget based approach.

What i did:

Create a scene, sceneView connect them and so...

... and I think the issue in your original code block is with this segment of the code:

QVariantMap att <SPAN class="" style="border: 0px;">=</SPAN> graphic<SPAN class="" style="border: 0px;">-</SPAN><SPAN class="" style="border: 0px;">></SPAN><SPAN class="" style="border: 0px;">attributes</SPAN><SPAN class="" style="border: 0px;">(</SPAN><SPAN class="" style="border: 0px;">)</SPAN><SPAN class="" style="border: 0px;">-</SPAN><SPAN class="" style="border: 0px;">></SPAN><SPAN class="" style="border: 0px;">attributesMap</SPAN><SPAN class="" style="border: 0px;">(</SPAN><SPAN class="" style="border: 0px;">)</SPAN><SPAN class="" style="border: 0px;">;</SPAN>

the QVariantMap is not returned by reference - therefore you need to call

graphic->attributes()->setAttributesMap(att);

to apply the height attribute to your graphics.

Hi Norbert,

I think the attribute you use in your extrusion expression needs to be in brackets - e.g.

props<SPAN class="" style="border: 0px;">.</SPAN><SPAN class="" style="border: 0px;">setExtrusionExpression</SPAN><SPAN class="" style="border: 0px;">(</SPAN><SPAN class="" style="border: 0px;">QLatin1String</SPAN><SPAN class="" style="border: 0px;">(</SPAN><SPAN class="" style="border: 0px;">"[height]"</SPAN><SPAN class="" style="border: 0px;">)</SPAN><SPAN class="" style="border: 0px;">)</SPAN><SPAN class="" style="border: 0px;">;</SPAN>

If you haven't already taken a look at our "ExtrudeGraphics" sample that might help give you some ideas as well (arcgis-runtime-samples-qt/ArcGISRuntimeSDKQt_CppSamples/Scenes/ExtrudeGraphics at master · Esri/arcgis-runtime-samples-q… ). The sample is written with a QtQuick UI but the C++ business logic should be essentially the same.

Please let me know if you are still having issues.

Thanks,

Luke

NorbertThoden

Hi Luke!

Your answer was very quick - amazing 🙂

Thanks for pointing me to the copyAndPaste error. But unfortunately the behaviour does not change (Static and Dynamic)

Yes, i took the logic from the ExtrudeGraphicsExample(QML)...

There are a couple of known issues for 3D, especially related to Graphics, RedneringMode and so on.

Do you have another hint?

Is there another example?

Thx

NorbertThoden

I try to get the QML example ExtrudGraphics running, but:

I don`t like to finish the postInstaller to not influence our project develpment.

And therefore i´m not able to run the example:

I get:

How can i set the import/module path/dir for this?

Hi Norbert,

Here's a snippet of our ExtrudeGraphics sample re-written for widgets UI. In theory it is possible to copy the toolkit etc. into your Qt kit and run those samples without running the PostInstaller but it is not recommended.

Does this code work for you?

Untitled10::Untitled10(QWidget *parent /*=nullptr*/):

  QMainWindow(parent),

  m_sceneView(nullptr)

  // Create a scene using the topographic BaseMap

  Scene* scene = new Scene(Basemap::topographic(this), this);

  // create a new elevation source from Terrain3D rest service

  ArcGISTiledElevationSource* elevationSource = new ArcGISTiledElevationSource(

        QUrl("http://elevation3d.arcgis.com/arcgis/rest/services/WorldElevation3D/Terrain3D/ImageServer"), this);

  // add the elevation source to the scene to display elevation

  scene->baseSurface()->elevationSources()->append(elevationSource);

  // Create a scene view, and pass in the scene

  m_sceneView = new SceneGraphicsView(scene, this);

  // set the sceneView as the central widget

  setCentralWidget(m_sceneView);

  // create a camera

  Camera camera(28.4, 83.9, 10010.0, 10.0, 80.0, 300.0);

  // set the viewpoint

  m_sceneView->setViewpointCameraAndWait(camera);

  // graphics location

  double lon = camera.location().x() - 0.03;

  double lat = camera.location().y() + 0.2;

  GraphicsOverlay* graphicsOverlay = new GraphicsOverlay(this);

  // set renderer with extrusion property

  SimpleRenderer* renderer = new SimpleRenderer(this);

  RendererSceneProperties props = renderer->sceneProperties();

  props.setExtrusionMode(ExtrusionMode::BaseHeight);

  props.setExtrusionExpression("[height]");

  renderer->setSceneProperties(props);

  SimpleFillSymbol* sfs = new SimpleFillSymbol(SimpleFillSymbolStyle::Solid, QColor("red"), this);

  renderer->setSymbol(sfs);

  graphicsOverlay->setRenderer(renderer);

  // setup graphic locations

  QList<Point> pointsList;

  for (auto i = 0; i <= 100; i++)

    Point point(i / 10 * (0.01 * 2) + lon, i % 10 * (0.01 * 2) + lat, m_sceneView->spatialReference());

    pointsList.append(point);

  foreach (auto point, pointsList)

    // create a random z value

    int randNum = rand() % 6 + 1;

    double z = 1000 * randNum;

    // create a list of points

    QList<Point> points;

    points << Point(point.x(), point.y(), z)

           << Point(point.x() + 0.01, point.y(), z)

           << Point(point.x() + 0.01, point.y() + 0.01, z)

           << Point(point.x(), point.y() + 0.01, z);

    // create a new graphic

    Graphic* graphic = new Graphic(createPolygonFromPoints(points), this);

    // add a height attribute to the graphic using the attribute list model

    // the extrusion will be applied to this attribute. See the expression above

    graphic->attributes()->insertAttribute("height", z);

    // add the graphic to the graphic overlay

    graphicsOverlay->graphics()->append(graphic);

  m_sceneView->graphicsOverlays()->append(graphicsOverlay);

// helper to create polygon from points

Esri::ArcGISRuntime::Polygon Untitled10::createPolygonFromPoints(QList<Point> points)

  Esri::ArcGISRuntime::Polygon polygon;

  if (points.length() == 0)

... and I think the issue in your original code block is with this segment of the code:

QVariantMap att <SPAN class="" style="border: 0px;">=</SPAN> graphic<SPAN class="" style="border: 0px;">-</SPAN><SPAN class="" style="border: 0px;">></SPAN><SPAN class="" style="border: 0px;">attributes</SPAN><SPAN class="" style="border: 0px;">(</SPAN><SPAN class="" style="border: 0px;">)</SPAN><SPAN class="" style="border: 0px;">-</SPAN><SPAN class="" style="border: 0px;">></SPAN><SPAN class="" style="border: 0px;">attributesMap</SPAN><SPAN class="" style="border: 0px;">(</SPAN><SPAN class="" style="border: 0px;">)</SPAN><SPAN class="" style="border: 0px;">;</SPAN>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; att<SPAN class="" style="border: 0px;">[</SPAN><SPAN class="" style="border: 0px;">QLatin1String</SPAN><SPAN class="" style="border: 0px;">(</SPAN><SPAN class="" style="border: 0px;">"height"</SPAN><SPAN class="" style="border: 0px;">)</SPAN><SPAN class="" style="border: 0px;">]</SPAN> <SPAN class="" style="border: 0px;">=</SPAN> <SPAN class="" style="border: 0px;">1000000</SPAN><SPAN class="" style="border: 0px;">;</SPAN>

the QVariantMap is not returned by reference - therefore you need to call

graphic->attributes()->setAttributesMap(att);

to apply the height attribute to your graphics.

Hi!

In the example code your wrote:

att<SPAN class="" style="border: 0px;">[</SPAN><SPAN class="" style="border: 0px;">QLatin1String</SPAN><SPAN class="" style="border: 0px;">(</SPAN><SPAN class="" style="border: 0px;">"height"</SPAN><SPAN class="" style="border: 0px;">)</SPAN><SPAN class="" style="border: 0px;">]</SPAN> <SPAN class="" style="border: 0px;">=</SPAN> <SPAN class="" style="border: 0px;">1000000</SPAN><SPAN class="" style="border: 0px;">;</SPAN>

Are values like 10.5 or 10,5 supported?

My experience is that the the ".5" is not used.

If i have a building consisting of 3 floors with an equal height of 2,5m the resulting cubes look not equal:

Do you have any information the the resolution of the values to the attribute "height" / "[height]"?

Or is there maybe a possibility to change the unit from meter to millimeter or similar?

Thank you!

That's great Norbert - I'm glad its working now
