I can answer your question for Windows environment. Same or similar solution MAY or
MAY NOT apply for Linux, I have no experience in Linux environment.
First you need to install Python Image Library, PIL, if you have not done so
already. You may be using it already, if you are using TEXTURE feature of
the recent Beta versions of VPython.
Then in your source code you need to add some lines, like the followings:
import Image
import ImageGrab
...
Your animation code goes here
...
while looping:
im = ImageGrab.grab((24,30,ImageWidth-4,ImageHeight-4))
fn = "Cat"+str(pn)+".png"
im.save(fn)
fn is the filename in Windows environment.
IF THIS SYSTEM WORKS in LINUX, then someting similar to that of filename should be sufficient.
ImageGrab needs the display location (upper-left corner) and display sizedefined to it, so it picks up
the image from the screen for you.
You need to set up some sort of a counter in the loop like the str(pn), to get a unique
file name for each snapshot.
Hope it works...
