scene.pickPosition cannot accurately pick the correct position in underground mode.

[wumanho]

What happened?

When I try to enable underground mode based on a Sandcastle example, I find that using pickPosition in events such as Cesium.ScreenSpaceEventType.MOUSE_MOVE and Cesium.ScreenSpaceEventType.LEFT_CLICK does not return the correct latitude and longitude coordinates.

And if set the option viewer.scene.pickTranslucentDepth = true, pickPosition seems to work correctly, but rotating the camera view results in a render error.

Please refer to the Sandcastle example I provide below for the reproduction. Thank you.

Reproduction steps

1. set scene.globe.translucency.enabled = true
2. create a mouse event handler like Cesium.ScreenSpaceEventType.MOUSE_MOVE

Hi @wumanho, what are you attempting to pick in this example? The terrain or the pipes beneath it? What values are you expecting see?

[wumanho]

Hi @wumanho, what are you attempting to pick in this example? The terrain or the pipes beneath it? What values are you expecting see?

Hi @ggetz , sorry, I didn't explain it clearly before.

I am trying to pick the latitude, longitude, and height of the terrain.

When I set the alpha value of the right panel to 1, I can get the expected terrain position, and the console logs numbers around 200, representing the terrain height.

However, if the alpha value is less than 1, the position I get is not what I expect, and the console shows height values like -10000.

The other problem I got is enabling viewer.scene.pickTranslucentDepth = true can lead to crashes. Please refer to this example for the reproduction. After performing a few rotate or zoom operations on the map, the problem will appear.

Thank you very much for your help.

Thanks for the explanation!

Ah yes, you will need to set viewer.scene.pickTranslucentDepth = true to pick translucent terrain.

It seems that I am not able to reproduce the crash on my end. I have ensured viewer.scene.pickTranslucentDepth = true, and have rotated and moved the camera throughout the scene.

@wumanho Would you be able to:

1. Copy and paste the full error text
2. Visit webglreport.com and take a screenshot of your results

Of course! 🙂
