Mouse Scroll Wheel Zoom Rate/Amount?

Also, yes, if you keep zooming in sometimes you end up in that weird opaque black zone. Did you try setting a maximum zoom level? You can do that when you create the scene:

viewer.scene.screenSpaceCameraController.maximumZoomDistance

Actually that only applies to the user scrolling with the wheel. Even when the maximumZoomDistance is set, it can be overridden by the camera.zoomIn method if you specify an amount that is too large. The code I included fixes that by limiting the amount to half the camera height.
