[vtkusers] Moving a glyph

[rakesh patil]

Well,

I didnt use glyph filter, but simple unstructured grid in my application and
my cells are vtkVertex type..

And i use vtkPointPicker to pick a vertex.. it works fine till now..

and to move a vertex, i pass my unstructured grid through
vtkProgrammableFilter.
eventhough this works, but it is very slow..

Hope that you'll come up with faster technique to implement this.. :-)

Thanks

Regards

Rakesh Patil

Yes, you're right, thanks.

I started doing all this glyph moving business when I decided I
couldn't click on a vertex. Can anyone confirm that there is no way to
select a vertex with a click (besides doing a rubber band + frustum
selection)? I guess the idea is that vertex glyphs are drawn directly
in window coordinates so they do not actually "exist" in the scene to
be picked?

Here is what I tried:
