[vtkusers] Re : [vtk 5.8.0] vtkCubeAxesActor and SetZAxisRange Problem

[R M]

Sometimes, I have a vtk error with the vtkCubeAxesActor and the SetZAxisRangeBut since, I don't set directly the text, is there a bug in this class ?

ERROR: In E:\libs\vtk\vtk-5.8.0\Hybrid\vtkVectorText.cxx, line 1728
vtkVectorText (06CD0F50): Text is not set!

ERROR: In E:\libs\vtk\vtk-5.8.0\Filtering\vtkExecutive.cxx, line 756

Thank you.

Can someone tell me if I do something wrong with my code or if it's a bug ?

Thank you.

Hello,

I have a display problem with SetZAxisRange  of vtkCubeAxesActor  (with vtk 5.8 on Linux and Windows).

I have a geometry that I scale along the Z axis (in order to have a better view).  I want to plot  bbox geometry info. So, I use vtkCubeAxesActo. 

Moreover, I want to have Zmin and Zmax of my orignal geometry and not the scaled values. So, I use SetZAxisRange to set zmin and zmax of my geometry.

I set the actor bbox of my geometry to the the vtkCubeAxesActor  (using SetBounds).

cubeAxesActor->SetBounds(pld->getActor()->GetBounds());
sp_cubeAxesActor->SetZAxisRange(geozMin, geozMax);

At each scaling, I set cubeAxesActor->SetBounds(pld->getActor()->GetBounds()); 


The bounds are OK but the Z Range is not updated when coming back to the orignal geometry scale.   When rotating, the other displayed Z axis are Ok but the one with the Z range problem is always affected. In attachment there is a screenshot of the problem.

Any idea to resolve this problem ? Is it a bug ?

Thank you.
