如何在 Mayavi 中设置缩放系数 [英] How to set zoom factor in Mayavi

问题描述

我正在尝试在 Mayavi2 中设置缩放系数，例如:

I am trying to set the zoom factor in Mayavi2, for example:

from mayavi import mlab

mlab.test_plot3d()
mlab.show()
f = mlab.gcf()
cam = f.scene.camera
cam.zoom(0.1)
mlab.draw()

但没有任何反应.变焦和以前一样；我错过了什么吗?

but nothing happens. The zoom is the same as before; have I missed something?

推荐答案

看来您刚刚倒置了 2 行.mlab.show() 和 mlab.draw() ！

It seems that you have just inverted 2 lines. mlab.show() and mlab.draw() !

试试这个:

from mayavi import mlab

currfig = mlab.test_plot3d()
mlab.draw()

cam = currfig.scene.camera
for ii in range(100):
  cam.zoom(0.99)
  mlab.draw()

mlab.show()
