How to render wallgeometry under the surface of globe.

var pos = WallGeometryLibrary.computePositions(ellipsoid, wallPositions, maximumHeights, minimumHeights, granularity, true);
        if (!defined(pos)) {

this line (line number 365 - 367) is not letting me render wall geometry under the surface of globe.
How to fix?

Subsurface rendering isn’t supported yet, but it looks like there is a PR open for it as Gabby mentioned here.

You can try reading what the computePositions function in WallGeometryLibrary does and try to compute the geometry yourself for under the surface. If you get it to work we’d definitely appreciate a contribution!

I fixed it.
