Updating the sceneview on geometry change

NorbertByiringiro — Fri, 19 Aug 2022 13:46:16 GMT

Hello folks,

I am trying to move a 3D object, feeding in the geometry values from the API, however the changes do not appear on my sceneview unless I reload the page.

...

const newGeometry = {

type: "point", // autocasts as new Point()

x: props.valueX,

y: props.valueY,

z: props.valueZ,

};

function updateGeometry(){

var objLayer = pointGraphic.layer

// clone old graphic and edit geometry

var newGraphic = pointGraphic.clone();

newGraphic.geometry = newGeometry;

// remove old graphic, add new graphic

objLayer .remove(pointGraphic);

objLayer .add(newGraphic);

}

updateGeometry()

...

Do you guys have any hint on how all the changes can appear directly on the map (sceneView) without reloading the page, thank you!

Have you tried adding the graphics to the SceneView in the updateGeometry function?

I am actually:

1. Creating a graphicsLayer and add it to the map on which I applied the view:

const graphicsLayer = new GraphicsLayer();

map.add(graphicsLayer);

2. Add the geometry and the symbol to create a graphic:

const pointGraphic = new Graphic({

geometry: point, //point is defined somewhere above

symbol: markerSymbol //markerSymbol is defined somewhere above

});

3. Add the graphic to the graphicsLayer/.

graphicsLayer.add(pointGraphic);

4. Update the this graphic inside the updateGeometry function shown in the first post.

However even when I try to add the newgraphic to the graphicsLayer inside the updateGeometry function, or even adding again the graphicsLayer to the map inside this function, It still requires to refresh the page for realising the changes.

Thanks @GeoJason

Hi @NorbertByiringiro!

It is hard to estimate what may be the issue with your app without having a closer look at your code.

Here's a simple app where one can move a boat symbol with keys:

Hope this helps you further! If not, could you share a similar simple app we could take a look at?
