Subject: [vtkusers] problem with different versions of vtkPointSet ! Help !



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.
Instead, I had to download the source code and compile it to install it on
my system now.
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)
it gives following errors.

when I checked the header files available with both installations,for
vtkPointSet::GetPoint, I found them different
vtkPointSet::GetPoint(int, double[])(installation using self compiled
binary)
vtkPointSet::GetPoint(int, float[]) (installation using precompiled binary)

Interestingly, the online documentation of vtkPointSet conforms to the
second signature and is not in accordance with the source code.


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
implementation.
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.

thanks for your time
