The viewer will survive simply closing the window. To wipe canvas from memory do:



In [11]:

    
pymaid.close3d() #or
viewer.close()



In [12]:

    
# Open two viewers
v1 = pymaid.Viewer()
v2 = pymaid.Viewer()

# Add neurons to each one separately
v1.add(nl)
v2.add(nl2)

# Clear one viewer
v1.clear()

# Close the second viewer
v2.close()
