[[Mark_center]] is a small callback that puts a cross at the center of space, where the camera is pointing.

You could also use this to setup arbitrary CGOs (points, lines, etc) in 3D space.

<source lang="python">
from pymol import cmd

def crosshair_put_center():
t = cmd.get_position()
m = [1, 0, 0, t[0], 0, 1, 0, t[1], 0, 0, 1, t[2], 0, 0, 0, 1]
cmd.set_object_ttt('crosshair', m, homogenous=1)

cmd.load_callback(crosshair_put_center, '_crosshair_cb')

cmd.pseudoatom('crosshair', pos=(0,0,0))
cmd.show_as('nonbonded', 'crosshair')
</source>
