[Visualpython-users] Implementing a head up display

[Frederic L. <fre...@ka...>]

Hello,

[ using vpython 3.2.9 , the standard package for ubuntu 9.03 , on an 
x86_64 box ]

I'm trying to make objects "stick" in front of the camera (see 
attached hud.py) . In theory, combining scene.forward and 
scene.mouse.camera should do the trick? However, I can see some delay 
in the repositioning when using userspin and userzoom. To me, this 
looks like scene.forward and scene.mouse.camera are not updated at the 
same time.

Am I right in my analysis ?
Any hint on what I could use to get this done with a smooth rendering ?

Thanks,
Regards,
