Multiple Viewports in Vizard, Utilizing keyboard callback

[shivanangel]

Hi,

I tried to create 4 viewports on the screen at once.
I have the main viewport, and then
3 viewports on the side.

I used a simple keyboard callback function to
turn the viewports on and off.

Below is the code I am using.

Everything works fine up until I press a,s, or d 4 times. After
the fourth press, Vizard will crash.

Is this just sloppy implementation on my part?

Also, the next thing I will be working on when these
viewports stop crashing is making the viewport
lock in on whatever the previous view was.

Can I simply set the
viewpoint of the window
to the main cameras view
and update it every time there
is a keyboard event (which in my
case will only make the viewports
turn on and off).

~~Thanks,

George
