[vtkusers] RE: quadratic elements

[James C. Robinson]

Mathieu,

I am using MFC 6.0 on PC.

I made the changes to vtkQuadraticQuad also.

The problem with the change from vtkInteractorStyle to vtkInteractorObserver
is I am calling AutoAdjustCameraClippingRangeOff as follows:

Interactor->GetInteractorStyle()->AutoAdjustCameraClippingRangeOff() ;

This code worked when GetInteractorStyle returned a vtkInteractorStyle. Now
I get the error:

C:\Jim\Programming\mfc\Kes\PanMeshv3.1\Source\meshviewView.cpp(223) : error
C2039: 'AutoAdjustCameraClippingRangeOff' : is not a member of
'vtkInteractorObserver'


I also get a problem with (a related bug):

Interactor->GetInteractorStyle()->OnChar(0,0,'w',0) ;

C:\Jim\Programming\mfc\Kes\PanMeshv3.1\Source\meshviewView.cpp(1501) : error
C2660: 'OnChar' : function does not take 4 parameters



Please advise.

Jim

Just to make sure. vtkQuadHexahedron is using internally vtkQuadQuad,
and I corrected the shape functions:

http://vtk.org/cgi-bin/cvsweb.cgi/VTK/Common/vtkQuadraticQuad.cxx

I would suggest you apply this changes too. BTW are you using linux ?
If so try something like this:

get the CVS head of VTK, then
cvs dif -r1.21 -r1.20  vtkQuadraticQuad.cxx > jim.patch
go back to your VTK 4.2 directory
do :
patch -p0 < jim.patch

and you can do it for any arbitrary revision number.

You shouldn't suffer from this:

http://vtk.org/cgi-bin/cvsweb.cgi/VTK/Rendering/vtkRenderWindowInteractor.h.
diff?r1=1.89&r2=1.90

As vtkInteractorStyle derive from vtkInteractorObserver. What  did you
try ? I guess this should only be a one line change.

Ps: I am CCing the list as it might interest other people.
