AW: [Visualpython-users] 1 objectlist and 2 displays

[Cettinich E. (LWE) <edw...@lw...>]

Thanks a lot. That helps.=20

Although I prefer a solution with exactly one object shown in two displays =
my hope has gone and I suppose it will not be realizable. So I'll go to imp=
lement some obj-management which can handle several displays.=20

By the way: There is no need to convert obj.__class__ to a character string=
=2E
Here's your program without dictionary:
################################
from visual import *

x =3D 300
y =3D 400
w =3D 200
h =3D 200
eyeangle =3D 0.15 # interocular angle
left =3D display(x=3Dx, y=3Dy, width=3Dw, height=3Dh)
right =3D display(x=3Dx+w, y=3Dy, width=3Dw, height=3Dh)
left.select()

b1=3Dbox(pos=3D(-1,0,0), color=3Dcolor.red)
b2=3Dbox(pos=3D(1,-1,0), color=3Dcolor.cyan)
a1=3Darrow(pos=3D(-0.5,0,0), axis=3D(1,-1,0), color=3Dcolor.yellow)

right.select()
for obj in left.objects:
    newobj=3Dobj.__class__()                       # create object in 2nd w=
indow
    for member in obj.__members__:
        if member =3D=3D 'display': continue # avoid putting into scene1
        exec 'newobj.'+member+'=3Dobj.'+member # set attribute

while 1:
    right.up =3D left.up
    leftforward =3D left.center-left.mouse.camera
    right.forward =3D rotate(leftforward, angle=3Deyeangle, axis=3Dleft.up)
