Dear all,
A question from the Structural Biology field. I would like to do an
isosurface rendering of a virus in which the color depends on the distance
to the center of the virus. My data are 3D arrays of floats and the center
of the virus is the center of the array.
Being a DX newbie,
Hello All.
I have the following problem.
I have a 3D grid with regular positions and connections, which represents
a volume containing several bodies (usually less than 10).
The data value is determined by following rule:
if position doesn't belong to any body than data=-1,
otherway data= body's

Hi,
I'm sorry about this message as my solution is probably very easy and I'm most
likely being a bit dim, but
I'm stuck with my dissertation! I'm meant to be using opendx to create 3D
images of DNA structures when I input the gene sequence (eg CGTA), and I
basically don't even know
I think I am missing something here... if I do what you suggest, I will
be mapping the DATA VALUES on the isosurface, right? But what I want to
map is the VOXEL POSITION. How can I feed this to the color module? I
tried with Compute, but couldn't figure out how.
Thanks,
Carmen
Thanks a lot! The Mark and Compute modules were the clue. The original
question and Chris Pelkie's answer are included below. A printout of my
final network is attached in case somebody is interested.

Extract the positions component to pass to Start, but
I don't think so.
What would be the best way to extract the positions? I'm pretty certain
Right after the Import, throw in an Extract module and set the
'which' parameter to positions. Then feed that into your 'start'
param.
