<!-- Converted from text/plain format -->
<P><FONT SIZE=2>I had to reinstall vtk on my system .I had devloped my code using vtk 4.4 by installing precompiled windows version available on the vtk Site which is no more offered.<BR>
Instead, I had to download the source code and compile it to install it on my system now.<BR>
when I try to run the code developed on previous installation(one using precompiled binaries for windows) on the new installation(one compiled by me)<BR>
it gives following errors.<BR>

*************************************************************************************<BR>
when I checked the header files available with both installations,for vtkPointSet::GetPoint, I found them different<BR>
vtkPointSet::GetPoint(int, double[])(installation using self compiled binary)<BR>
vtkPointSet::GetPoint(int, float[]) (installation using precompiled binary)<BR>
<BR>
Interestingly, the online documentation of vtkPointSet conforms to the second signature and is not in accordance with the source code.<BR>
<BR>
<BR>
I presume the implementation of vtkPointSet::GetPoint() has been changed in later releases. If the implementation of vtkPointSet is changed in vtk 5, why is the online documentation still inline with previous<BR>
implementation.<BR>
Is there any quick fix to this problem or I have to change the source code and recompile vtk.I MUST need float instead of double.<BR>
<BR>
thanks for your time<BR>
