In the spirit of the detailed review of the spec., a clarification of the
coordinate system of the center of rotation position given with a viewpoint
node may be appropriate.
Since the position of viewpoint is given in the local coordinate system, I
would have expected that the center of rotation is also given in the local
coordinate system. However, the spec. at
does not spell out the coordinate system for the center of rotation
position, and x3dom currently uses the world coordinate system for the
center of rotation, see issue https://github.com/x3dom/x3dom/issues/504.
although this may be an oversight.
If the intention is to use the local coordinate system for the center of
rotation position, it may be useful to spell it out in the spec. as well.
