Description
1. Run the materials demo: http://localhost:8080/Apps/Sandcastle/index.html?src=Materials.html&label=All
2. Switch to 2D.
3. Select Polyline Arrow from the bottom combo box.
4. Switch to 3D
5. The polyline will be drawn even when it is behind the ellipsoid (it does disappear at some point when it's completely on the other side of the center of the earth)
Contributor guide
Research direction
Reproduce the issue in the Materials demo using the Polyline Arrow: switch from 2D to 3D and observe its behavior behind the ellipsoid. Trace the geometry culling path for this transition and verify the fix by confirming that hidden polylines no longer render behind the ellipsoid.
