Hmm, clicking on down button I see nothing special. Some button
produce no output because of problems in the examples. Namely,
by default Scene is not exposed, so interpreter do not search
for functions there. So first command should be
)expose SBoundary Scene STransform
(or alternatively you qualify all calls to functions form Scene,
SBoundary and STransform).
Then I see line:
addSceneMaterial(sc,3::DF,"blue","green")$Scene(SCartesian(2))
this line depends on definition of DF (standard FriCAS abbreviation
is SF), so needs extra annotation to indicate dependency, otherwise
it will not execute correctly alone (dependenes mean that
previous lines will be run befor this one). There is also
lines containing continuation characters and it causes trouble.
So definitely there are few things to fix on this page, but I see
no crash, just there is no expected output.
