I have try to get an image that is reflected by a mirror.
The image should be reversed by left/right direction.
So I defined a view frustum as below.

......
chan->makePersp(right,left,bottom,top);// left < right
......

The image I get was partialy reversed,but seemed to be created by wrong culling.
So I changed cull-callback function as below.

......
chan->makePersp(left,right,bottom,top);// left < right
pfCull();
chan->makePersp(right,left,bottom,top);// left < right
......

It works right in multi process mode. (Cull and Draw are not in same process)
But if Cull and Draw are in same process,
I still get an image created by wrong culling.

My questions are...
1.Why I get different results?(multi process mode/single process mode)
2.Are there more formal ways to get reversd image?

Thanks for any help.
