Summary0009614: vtkVolumeTextureMapper3D::UpdateVolumes(...) calls Modified() method too early
DescriptionThe calls to:
  this->SavedTextureInput = input;
  this->SavedTextureMTime.Modified();

should be placed at the end of the method instead of the begining, because at line 1103: input->GetPointData()->GetScalars()->GetRange(scalarRange, components-1);
will modify the input->GetMTime() return value, so if we enter again in UpdateVolumes() the computations will be done without need of it.

This is needed since revision 1.80 of vtkDataArray.cxx because the method vtkDataArray::ComputeRange modify the MTime, wich was not the case before.
Steps To Reproducecreate a pipeline using vtkVolumeTextureMapper3D and call the method Render() twice: the method UpdateVolumes will perform its computations twice instead of returning 0 the second time

Does the problem still occur with VTK 5.10 ? VTK 6 ?

Would be great if you could submit a patch using Gerrit. For more details see http://www.vtk.org/Wiki/VTK/Git/Develop [^]

Thanks
