[Algorithms] Rendering (a portion of) a Plane

[Jeremy B. <Jer...@in...>]

I've been working on my viewport culling and I just wanted to test something
out
I was wondering if anyone could tell me how to render a portion of a plane
around
a particular point using the 
Normal + distance version of a plane.
I think it relates to 
Normal[0] * X + Normal[1] * y + Normal[2] * z + distance = 0
but I can't seem to get my head around how I could draw this function
over a specific range...  any help would be Greatly appreciated
