Picking is selecting the wrong feature

Open eric-g-97477 opened this issue 1 year ago • 1 comments

What happened?

I clicked on a feature on the globe and it selected the furthest object found instead of the nearest.

I expected the nearest object to be selected.

Reproduction steps

  1. Use the provided sandcastle
  2. Click somewhere in the area outlined by the red square

  1. What shows up is:

  1. If I click most other places in that same green polygon, I get the correct answer which is:

Rotating the globe so that IDN polygon is no longer beneath the CAN polygon results in the correct behavior because only a single polygon can be found at the click location.

What I did notice is that if I set clampToGround: false, then the picking works correctly. However, it would be useful to me to be able to have picking work correctly with clampToGround: true.
