In SceneView, zooming out using the mouse wheel does not behave as expected

Lerman — Wed, 11 Oct 2023 01:57:30 GMT

Hello everyone,

In SceneView, when zooming out the view using the mouse wheel, the behavior is not as expected. SceneView takes the mouse's current position as the view center and zooms out around that point, causing the mouse's position to constantly change. This behavior is abnormal, and there are two reasons for it:

1. When users zoom out the view using the mouse wheel, they expect the view to shrink around the mouse's location, meaning that the geographical coordinates at the mouse's position should remain unchanged when zooming out the map.

2.In SceneView, zooming in on the view using the mouse wheel does not exhibit this behavior. Additionally, in MapView, zooming in and out using the mouse wheel does not exhibit this behavior either.

I have recorded an video that demonstrates the zoom-in and zoom-out processes in SceneView.

This issue can be reproduced in any SceneView demo, for example, here: https://developers.arcgis.com/javascript/latest/sample-code/intro-sceneview/live/

Does anyone know how to resolve this issue? Thank you so much!

Hello @Lerman , this behaviour is described in Esri's defect system in BUG-000130778. However, the defect is Closed with the Public Explanation "This is as designed for zooming in and out in 3D.".

If the current user experience causes any limitations for your end users, please contact your local Esri distributor for the question to be revisited.
