I put two separate sliders for a stl to move it in X direction and Y direction.
For connecting sliders value to position I wrote the code below
#First STL file
reader = vtk.vtkSTLReader()
reader.SetFileName(filename)
self.transform = vtk.vtkTransform()
self.transform.Scale(1, 1, 1)
self.transformFilter = vtk.vtkTransformPolyDataFilter()
self.transformFilter.SetTransform(self.transform)
self.transformFilter.SetInputConnection(reader.GetOutputPort())
self.transformFilter.Update()
mapper = vtk.vtkPolyDataMapper()
if vtk.VTK_MAJOR_VERSION <= 5:
mapper.SetInput(self.transformFilter.GetOutput())
else:
mapper.SetInputConnection(self.transformFilter.GetOutputPort())
self.actor = vtk.vtkActor()
self.vtkwidget = QVTKRenderWindowInteractor(self.centralwidget)
self.gridLayout.addWidget(self.vtkwidget, 0, 0, 1, 1)
self.ren = vtk.vtkRenderer()
self.vtkwidget.GetRenderWindow().AddRenderer(self.ren)
self.iren = self.vtkwidget.GetRenderWindow().GetInteractor()
self.actor.SetMapper(mapper)
self.ren.AddActor(self.actor)
self.iren.Start()
self.horizontalSlider = QtWidgets.QSlider(self.centralwidget)
self.horizontalSlider.setGeometry(QtCore.QRect(70, 360, 291, 22))
self.horizontalSlider.setMinimum(-100)
self.horizontalSlider.setMaximum(100)
self.horizontalSlider.setProperty("value", 0)
self.horizontalSlider.setSliderPosition(0)
self.horizontalSlider.setOrientation(QtCore.Qt.Horizontal)
self.horizontalSlider.valueChanged.connect(self.handler)
self.horizontalSlider_2 = QtWidgets.QSlider(self.centralwidget)
self.horizontalSlider_2.setGeometry(QtCore.QRect(70, 410, 291, 22))
self.horizontalSlider_2.setMinimum(-100)
self.horizontalSlider_2.setMaximum(100)
self.horizontalSlider_2.setProperty("value", 0)
self.horizontalSlider_2.setSliderPosition(0)
self.horizontalSlider_2.setOrientation(QtCore.Qt.Horizontal)
self.horizontalSlider_2.valueChanged.connect(self.handler2)
def handler(self, value):
self.positionx = value
self.actor.SetPosition(value, 0, 0)
self.iren.GetRenderWindow().Render()
def handler2(self, value2):
self.positiony = value2
self.actor.SetPosition(0, value2, 0)
self.iren.GetRenderWindow().Render()
(This is just a part of the program)
but as you see when I change one direction (for example X) all applied directions(Y or Z) before that removed and stl file start to move from the beginning position(0 ,0 ,0).
Is there any way to merge these two sliders output to work together?
Or merge two handlers into one?
