[vtkusers] VolumePro support in VTK 5.0.0

[Kent Ogden]

Lisa,
 
Thanks for the response.  I will use v4.4.2 for my project, if I can get
the VolumePro classes to compile.
 
I still have an issue when adding the volumepro support, even in 4.4.2.  I
get a large number of ambiguous symbol errors (see earlier post below),
apparantly related to the namespace vli3 that is defined in
vtkVolumeProMapper.h.  This is particularly frustrating because during my
initial learning curve of using cmake and compiling vtk numerous times I'm
pretty sure I had a good compile without these errors.  I get them now,
though, on two different computers using the .Net 2003 compiler and with the
VC++6 compiler, so maybe I was dreaming the good compiles.  I am (obviously)
not a C++ guru and have little experience with namespaces, so looking at the
class header files and implementations has not revealed any obvious issues
to me.  Perhaps there is a compiler setting or something similar I am
missing?
 
Any thoughts, workarounds (even painful ones if doable) would be greatly
appreciated!
 
Kent

Hi Kent,

VTK does not support VolumePro in VTK 5.0 (those classes should have been 
removed).

We have not been keeping up-to-date with the changes in vli and therefore 
it is likely that the classes (as exist in the repository) will not work 
with newer version of vli (although I suspect the changes are fairly
minimal).
