What you really need is our book "OpenDX: Paths to Visualization". It
would explain what you need to use Isosurface and you could deduce
why it isn't working. But the short of it is, ReadImage only imports
a 'colors' component with no data. You need to somehow convert the
'colors' to data. If you Mark('colors') and then use a compute to
turn them into a scalar then you can send it to Isosurface.

Hi!
I've tried several hours to get along with OpenDX, read the
User-Reference, searched the web etc. but can't get along with what I
want to do.
I have a tiff-file with 16 Frames; slices of a Chloroplast
made with a laser scanning microscope and I like to render a zoomable
and rotationable 3D-model from this data. I started building the
appropriate network with FileSelector -> ImageReader -> Filter ->
Display. I know that I need some more modules to get this working and
looking good, Isosurface and Slab is needed, Autocolour and Histogram
would also be fine to correct the brightness etc of the images. Whenever
I try to build FileSelector -> ImageReader (-> Filter) -> Isosurface or
-> Autocolour I get an Error: Field is missing "data" component. I don't
have any idea what data field is needed to be set in those modules
because I have picture files as input data.
Is there any way to derive another datatype from my tiffs p.ex. with
convert and compute or am I missing something else? Has anyone build an
example network to do something like I what to do and can share his/her
experiences with me?
Thank you very much for your help!!!
Frank
