我正在寻找一种捕获键盘事件的方法,以便在mayavi动画中循环浏览不同的数据集。
我的基本循环是:
while 1:
time = TIME() - zero
wx.Yield()
atomsanim[:,:3] = atoms[:,3:]*cos(speed*time) + atoms[:,:3]
f.scene.disable_render = True
atom_index = 0
for t, p in zip(types, plots):
ms = p.mlab_source
start = atom_index
stop = atom_index+t
ms.set(x=atomsanim[start:stop,0],y=atomsanim[start:stop,1],z=atomsanim[start:stop,2])
atom_index += t
f.scene.disable_render = False
mlab.show()
在谷歌搜索后,我发现了这个页面:http://osdir.com/ml/python-enthought-devel/2009-01/msg00325.html
这几乎为我解决了问题
scene.interactor.add_observer('KeyPressEvent', your_function);
def your_function(vtk_obj, event):
... and then play with vtk_obj.GetKeyCode()
