<DIV><FONT size=2>Hi,</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>I have a couple of questions:</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>1. I'm trying to find the best way to visualize a data
set consiting of x, y, z data plus 2 scalar values per data
point. The data is not always on a grid. I am able to visualize
the x,y,z data points ok- I am not sure of the best way to mix in the data
set. I'm using vtkPoints for the x,y,z data.</FONT></DIV>
<DIV><FONT size=2>I am looking at vtkProgrammableAttributeDataFilter
and vtkProgrammableGlyphFilter to map the scalar data to the point data- is this
the best way to proceed? Are there alternate methods?</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>2. Picking- I'm using spheres as glyphs in my data
pipeline above. If I want to pick just one of the spheres (out of
hundreds/thousands) - I always end up selecting all the spheres. Is there
a way to select just one or two of the points and not all?</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Any tips/suggestions/advice would be greatly
appreciated.</FONT></DIV>
