Hi Elyas,
OK, I took a deeper look, and consulted with Ken Moreland. We think what you
are trying to do can't be done, or if it can, it is very inefficient. There
are two filters of interest, the Rotational Extrude filter and the Angular
Periodic filter.
The Rotational Extrude filter takes a 2d object and rotates it in space,
creating a disk or cylinder. It must be polygonal data. You can create
polygonal data with the extract surface filter. The Rotational Extrude filter
will rotate your 2d object on the z axis. If you want to rotate on a different
axis, use the Transform filter to rotate your data to be lined up with the Z
axis. But, here is the kicker. The output of the Rotational Extrude filter is
a 2d surface, In other words, this filter's output is hollow. It will look
good if you don't clip or slice it. You can see that it is hollow with a slice
filter.
The Angular Periodic filter will also rotate objects (i.e., pie slices) around
an axis. However, it won't fill it in if your data was originally 2d. If it
is pie slices, you will get a nice cylinder. But, with your data, you will
just see a lot of 2d planes, rooted at the center of a cylinder, and fanning
out to form this sparse cylinder. I tried the Delauny3d filter, and it hung.
Ken's advice if this is necessary is to write a custom filter.
Sorry I couldn't help more,
Alan

I don't know that filter well. Try playing with it, and if it doesn't
cooperate, let me know. I will then try...

Hi Scott,
Thanks. It worked. Now the filter is active. However, I am not sure
what normal and origin coordinate I should put for the Slice filter to end up
with a 3D cylinder rotated about y axis.
Do you have any clue?
I am OK to move it to the e_mail list.
Best,
Elyas

Just a guess - this filter requires 2d polygonal data. What I just did
was Wavelet, then Slice. Maybe your data is actually 3d? Try running a slice
filter on it first?
Mind moving this to the parav...@paraview.org e-mail list, so everyone
can see the answer?
Thanks,
Alan

Hi All,
I have an axisymmetric 2D model in Paraview in x-y plane. I am
trying to use the Rotational Extrude filter to rotate the model about the
y-axis and make it a 3D model. However, the filter is iactive. Does any one
have an idea of how to solve the issue?
Best,
Elyas
