Zooming does not track cursor position with `globe: false` #11679

Open jjhembd opened 11 months ago

jjhembd commented 11 months ago

In the current 3D Tiles Next Globe Sandcastle, the Viewer is initialized with globe: false. Zooming with the scroll wheel does not track the cursor position.

This can be fixed by initializing with a globe, and then setting globe.show = false;. See this updated Sandcastle:

This non-tracking behavior also appears to have been introduced to the Google Photorealistic Tiles Sandcastles by https://github.com/CesiumGS/cesium/pull/11542.

@jjhembd After the globe is hidden, the pick method will not be executed to get the world coordinates. https://github.com/CesiumGS/cesium/blob/31293c147e9e14a32ba3d6e04662198e5874fed4/packages/engine/Source/Scene/ScreenSpaceCameraController.js#L625-L631

The problem was solved by making the following changes:

} else {
  pickedPosition = pickPosition(
    object,
    startPosition,
    scratchPickCartesian
  );
}

But this is obviously not a good solution.

Reported on the forum. This is important for global tilesets that act as terrain like the Google tileset
