Patrick et al,
I wonder if it is possible to change the points (attribute positions) of
a geometry (in the batching branch)?
I'm asking because I'm working on the WallGeometry which would be offset
from the terrain elevation, and I'd like to update the points based on
the async return from sampleTerrain(). simply overwriting the
attributes.position.values values doesn't seem to work. my aim was
that from within WallGeometry, the callback called after sampleTerrain
returns with simply update the necessary positions.
