the problem seemed to be that there was more than one meshed region. by
increasing the radius in autogrid to 1 I got a single meshed surface and the
problem was solved.
apparently isosurface is not happy with a set that consists of more than one
region. is there a way to connect sets or is increasing the radius in
autogrid the only solution to this problem.

If the problem happens with software rendering, it's not GL. I've
seen similar issues in HW rendering, but if in software, there must
be a bogus mesh point, probably at the origin or something that did
not get set 'invalid' but should be.

dear opendx users,
I try to create an isosurface from scattered data. I send my data
through
autogrid to create a mesh and send the output to isosurface. the
output is
what i want and expected but there seems to be a problem during
rendering. i
get strange surfaces extending from the surface to some point
outside it.
when i rotate my image the point to which they extend changes as
well with
software rendering and stays the same with hardware rendering. Is
this a bug
in opengl or is the gridding incorrect possibly because of the way
the data
is scattered? I get it with different layout of the points making
this more
unlikely.
my system and dx info is in my previous mail about smp problems :)
