我正在用VTK python做一个动画程序,我不明白如何停止或暂停 这个动画。有人请告诉我如何停止这个计时器。现在我的动画 正在继续无限的时间,我试图将我的代码放入for循环,但它没有停止。 请注意我的下面代码,并且有人会分享一些想法。
代码行:
renderWindowInteractor.AddObserver('TimerEvent', cb.execute)
timerId = renderWindowInteractor.CreateRepeatingTimer(10);
详细代码行:
class vtkTimerCallback():
def __init__(self):
self.timer_count = 0
self.timerCycle=0
def execute(self,obj,event):
self.timerCycle+=1
if self.timerCycle==3:
self.timerCycle=0
for A in range(3):
for B in range(2):
for C in range(1):
self.actor.SetPosition(A,1,C);
iren = obj
iren.GetRenderWindow().Render()
self.timer_count += 1
else:
for X in range(1):
for Y in range(2):
for Z in range(3):
self.actor.SetPosition(1,Y,Z);
iren = obj
iren.GetRenderWindow().Render()
self.timer_count += 1
class Cone():
def animation(self,obj_renwin):
renderwininstance=obj_renwin
renderWindowInteractor = vtk.vtkRenderWindowInteractor()
renderWindowInteractor.SetRenderWindow(obj_renwin.renwin)
obj_renwin.renwin.Render()
renderWindowInteractor.Initialize()
cb = vtkTimerCallback()
cb.actor = obj_renwin.actor
for X in range(2):
print "animation time is" + str(X)
renderWindowInteractor.AddObserver('TimerEvent', cb.execute)
timerId = renderWindowInteractor.CreateRepeatingTimer(10);
cone_Obj = Cone()
答案 0 :(得分:0)
我猜你用定时器进入vtkRenderWindowInteractor对象,在那里启动定时器:
renderWindowInteractor->CreateRepeatingTimer(100);
所以,vtkRenderWindowInteractor可以暂停,并停止计时器:
