and so on. Just define each field (each curve), then collect them into a multigrid.
Import this file and use the same net I provided earlier, or get fancy and add additional tools (Select) to
select out some subset of the curves, by their member ID (number).
How's the weather at U-Tokyo this year? It was beastly hot and humid last time I was there (Aug-97).

Hello all,_______________________________
I'm quite new to OpenDX. I've read (not all, but relevant parts of)
the QuickStart and User's Guides, but I'm still struggling to try to
find a solution to my problem.
I want to visualize many, many 3D curves on the same screen
(image) at the same time. I've found the following past email
message in this list:

which showed how to draw a single 3D curve. My question is
how to extend this idea to many curves (or if that's infeasible,
what is an alternative method).
To summarize the method shown in the past message:
####### BEGIN THE .DX FILE ###########################
#positions component
object "my_pos" class array type float rank 1 shape 3 \
items 120 data follows
x y z
x y z
...
#connections component (1-D line in 3-space)

#data component (optional)

#the field
object "my_field" class field
component "positions" value "my_pos"
component "connections" value "my_conn"
component "data" value "my_data
########### END THE .DX FILE #########################
and visualize the this curve with "Import" -> "AutoColor"
-> "ShowConnections" -> "Image".
This works. But how can I extend this to hundreds or thousands of
curves? (and I need to draw at least hundreds of curves on a single
screen.)
Sorry if this is so trivial, in which case I'd appreciate it very
much if you could kindly tell me where to look.
Thank you for your attention,
Ryo
