Instead of showing up exactly on the corners of the cube they show up slightly offset, the min tick mark is a little to the positive side of its corresponding value and the max tick mark is a little to the negative side. Initially I thought I might have been using the class incorrectly, but I’ve looked at a number of examples and other user’s code and it seems the axes always work this way. Does anyone know whether this is the intended behavior or a bug? Any ideas on how to adjust it so the tick marks show up right at the corners of the cube? Here is a simple example that shows the issue. The geometry is an outline of a unit cube. When it renders, the labels for 0 and 1 are a little offset from the corners of the cube.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>import vtk<o:p></o:p></p><p class=MsoNormal>from vtk.util.misc import vtkGetDataRoot<o:p></o:p></p><p class=MsoNormal>VTK_DATA_ROOT = vtkGetDataRoot()<o:p></o:p></p><p class=MsoNormal>outline = vtk.vtkOutlineSource()<o:p></o:p></p><p class=MsoNormal>outline.SetBounds(0,1,0,1,0,1)<o:p></o:p></p><p class=MsoNormal>mapOutline = vtk.vtkPolyDataMapper()<o:p></o:p></p><p class=MsoNormal>mapOutline.SetInputConnection(outline.GetOutputPort())<o:p></o:p></p><p class=MsoNormal>outlineActor = vtk.vtkActor()<o:p></o:p></p><p class=MsoNormal>outlineActor.SetMapper(mapOutline)<o:p></o:p></p><p class=MsoNormal>outlineActor.GetProperty().SetColor(0,0,1)<o:p></o:p></p><p class=MsoNormal>renWin = vtk.vtkRenderWindow()<o:p></o:p></p><p class=MsoNormal>renWin.SetSize(600, 600)<o:p></o:p></p><p class=MsoNormal>ren = vtk.vtkRenderer()<o:p></o:p></p><p class=MsoNormal>renWin.AddRenderer(ren)<o:p></o:p></p><p class=MsoNormal>iren = vtk.vtkRenderWindowInteractor()<o:p></o:p></p><p class=MsoNormal>iren.SetRenderWindow(renWin)<o:p></o:p></p><p class=MsoNormal>axes = vtk.vtkCubeAxesActor2D()<o:p></o:p></p><p class=MsoNormal>axes.SetInput(outline.GetOutput())<o:p></o:p></p><p class=MsoNormal>axes.SetCamera(ren.GetActiveCamera())<o:p></o:p></p><p class=MsoNormal>ren.AddViewProp(axes)<o:p></o:p></p><p class=MsoNormal>ren.AddViewProp(outlineActor)<o:p></o:p></p><p class=MsoNormal>iren.Initialize()<o:p></o:p></p><p class=MsoNormal>ren.ResetCamera()<o:p></o:p></p><p class=MsoNormal>renWin.Render()<o:p></o:p></p><p class=MsoNormal>iren.Start()<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Cheers,<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Adam<o:p></o:p></p></div></body></html>
