[vtkusers] Point data to Surface

[Kiran, P (CORP, GEITC)]

Hi Johan,

I am trying following method to solve the problem:

1.  First read the x y z points into vtkPolyData 
2.  Pass the vtkPolyData through   vtkSurfaceReconstructionFilter.
3.  Send the output of step2  through vtkContour filter.
4.  Use the PolDataMapper, Actor, Renderer to view the output of step3.

I am sending the sample tcl file which I am using to generate the surface
for my data.  
( In this tcl file my data format is:
   6
   0 0 0 0
   n(=no. of points)
   x1  y1 z1
   x2 y2 z2
  ...................
  ..................
  xn yn zn )
 

If you have any problems let me know.

Regards
Kiran

Hello users, 

I have a set of data from which I want to create a surface.

x      y      z

0     0      6
0     1      7
0     2      7
0     3      7
 .
.
 .
1     0      6
1     1      7
1     2      7
1     3      7
 .
.
 .
etc.

Does anyone have a suggestion of how to make a mesh from that data? I have
tried to put the data into three arrays from which I created a vtkDataSet.
How can I proceed from there? I have tried to use vtkDataSetSurfaceFilter
but my installation of VTK misses that h-file.

Regards
