如何使轴 x,y,z 看起来像
from visual import *
f = frame()
# Axis
pointer_x = arrow(frame=f, pos=(0,0,0), axis=(40,0,0), shaftwidth=1, color = color.red)
pointer_y = arrow(frame=f, pos=(0,0,0), axis=(0,40,0), shaftwidth=1, color = color.blue)
pointer_z = arrow(frame=f, pos=(0,0,0), axis=(0,0,40), shaftwidth=1, color = color.green)
# Show X,Y,Z labels
label(frame=f,pos=(40,0,0), text='X')
label(frame=f,pos=(0,40,0), text='Y')
label(frame=f,pos=(0,0,40), text='Z')
