Z index in 3D for billboards/points

CesiumJS
1

hi,
in COLUMBUS_VIEW, with HeightReference.CLAMP_TO_GROUND prop in all entities, I want to implement a point below the rectangle. I know that Cesium purposely did not implement Z INDEX to the point due to the nature of the point entity,

the question is if there is still a way to implement it.

Sample code:
<Entity

     rectangle={{
      coordinates: Rectangle.fromDegrees(34.5007, 30.5046, 37.5007, 35.0046),
      material: Color.DARKSLATEBLUE,
      heightReference: HeightReference.CLAMP_TO_GROUND,
      zIndex: 100,
    }}

/>

And the point will appear below the rectangle.

with gratitude, israel

Hi there,

If I understand correctly, you would like to render a point below the rectangle, which is clamped to ground?

For that point, I would swap CLAMP_TO_GROUND for RELATIVE_TO_GROUND and provide a position with a negative height. I would also set disableDepthTestDistance to Number.POSITIVE_INFINITY so that the point is not occluded by the ground.
