Hi,
Sorry for the long email, but I am trying to clearly explain my
situation.
I have some data that describes a closed 3-d surface. The data
could describe a cell membrane, or the surface of a balloon for
example. The data points are in spherical coordinates
[theta,phi,r], and it is garaunteed that for each pair of
[theta,phi] there is only one value of r. The data comes in a
file where the [theta, phi] values are regularly arranged. For
example, if the data described a sphere of radius 1, it could
look like:
0 30 1
0 60 1
0 90 1
...
0 360 1
30 0 1
30 60 1
...
30 360 1
...
180 360 1
I am trying to produce the 3-d surface that displays the data. I
have one solution, but it seems very inelegant and crude to me.
My solution is as follows. First, I use a simple external program
that converts the data in Cartesian coordinates. Then,
because the data is ordered in [theta,phi], I have another
program that produces for me a file with triangular connections
for the data. This is messy, and hardly general, since it
depends on the data being ordered in a particular way. Finally,
with these two outputs (points in Cartesian coords and
connections) I make a .dx file for OpenDX and use the Data
Importer.
There must be a more direct was to get OpenDX to plot the
surface directly from the data?
Thanks
