back face rendering

Hi guys,

I am not sure how to do this in Blender so maybe some of you can help.

I have a project required me to render only the polygon faces the camera. For those face away from camera, do not render (not sure if it is called back face culling).

I am got that all the time in some other sofrtware like lightwave in the old days but cannot replicate it even with the double sided button off in the object. I am not sure where to set it.

I am using 2.53 beta at the moment.

Thanks for helping.
