glScissor for a circular area?

[elias4444]

Anyone know if there's a way to do something like glScissor for a circular area?

I'm using a circular radar, and don't want objects drawing outside of the radar screen area. I only display items that are in the radar range, but some objects are big and draw partially inside and outside.

Use the stencil buffer.

Yeah... I've avoided using the Stencil Buffer thus far (it intimidates me). Guess I better go do some reading on it.
