[vtkusers] Re: vtk+ point cloud reconstructiong

[sai pritham]

Hi ,
   I have a task of generating a surface from point data set. I have text file containing x y and z coordinates.

The link mentioned in this email 

http://public.kitware.com/pipermail/vtkusers/attachments/20060526/257e3317/ReconstructSurface.obj

doesn't seem to work.


The following snippet seems to be wrong with the code

int iNo = points->GetNumberOfPoints(); 
for (int i=0; iInsertNextCell(1,&i); 
data->SetPolys(polys); 
polys->Delete(); 

Could some one please help me with getting the proper code.

I have done the following modification to the code

int iNo = points->GetNumberOfPoints(); 
for (int i=0; i<iNo;i++)
{
	iInsertNextCell(1,&i); 
	data->SetPolys(polys); 
}
polys->Delete(); 

The result is that i get a arbitrary surface and at an offset distrance from the cloud of points.

What i needed is the surface to be generated out of these points.

Thanks a lot for your time

Could some one modify the code and help me in  getting the surface at the proper location

Thanks
Sai
