<br>
When vtk loads a model in vtkPolyData format, it populates its POINTS
list and the index to that point list is used further to
populate POLYGONS list and so on .<br>
<br>
Could you please tell me from which point of a given model, vtk starts populating
its point list.To put it other way, which point of the whole data set becomes
the first to appear in the Point list of vtkPolyData. For example,why did vtk
started to populate the POINTS list from 0.0, 0.0, 0.0 in the following
listing; why not some other point.<br>
<br>
<br>
<br>
# vtk DataFile Version 2.0<br>
Cube example<br>
ASCII<br>
DATASET POLYDATA<br>
POINTS 8 float<br>
<br>
0.0 0.0 0.0<br>
1.0 0.0 0.0<br>
1.0 1.0 0.0<br>
0.0 1.0 0.0<br>
0.0 0.0 1.0<br>
1.0 0.0 1.0<br>
1.0 1.0 1.0<br>
0.0 1.0 1.0<br>
POLYGONS 6 30<br>
4 0 1 2 3<br>
4 4 5 6 7<br>
4 0 1 5 4<br>
4 2 3 7 6<br>
4 0 4 7 3<br>
4 1 2 6 5<br>
<br>
This is very important for me though it seems trivial.I would highly appreciate
your help.<br>
