Hi.

Well, I've got someone else checking the math, so that I can be sure about

(6) - which is to get s. Certainly you have given everything  to be able
to 
compute the intersection point (P(s). As long as we have Ro + t Rdir = Po
+ 
s (P1 - Po) we can begin to work things out.

The next step is to figure out the math to get Rdir in terms of x and y,
for 
the next line segment (ray), the ray that is reflecting off the first
line. 
I'll give it some thought.

You have already been very helpful, thanks a lot.

Richard
