I'm curious as to how you actually generate "eye-rays". Given 3space, with the eye a point in 3space and some window with resolution (max,maxy); I suspect I should build a vector from the eye to a point (X,Y) in the window plane. So if I have Plane = (Xp,Yp,Zp) and Eye = (Xe,Ye,Ze) (with i,j,k unit): v = | Xp - Xe| i + | Yp - Ye| j + | Zp - Ze| k This might seem like a painfully obvious question, but I'm (re)learning math as a function of programming. :-) In case you're curious, I'm writing a simple exhaustive ray-tracer to drive various parallel memory management system benchmarks. I hope that it will grow into a "real" parallel raytracer (future thesis plans :-). -- J.
