in the latest minimals (2012.09.06 23:03) the following  example from
back-u3d.mkiv fails to work

\useexternalfigure  [test]  [test.prc]  [width=0.5\textwidth,
height=0.5\textwidth, display=u3d:myset:display:1,
controls=u3d:myset:controls:1]
\placefigure[here]{3d test}{\externalfigure[test]}

while after getting rid of \texwidth the following does:

\useexternalfigure  [test]  [test.prc]  [width=3in,   height=3in,
display=u3d:myset:display:1, controls=u3d:myset:controls:1]
\placefigure[here]{3d test}{\externalfigure[test]}

Is it a bug of the example got wrong with some changes in ConTeXt.

        Sincerely, Michail
