Interesting article. A few years back I implemented a bunch of maths primitives, including trig functions, using Taylor sequences etc, to see how it was done. An interesting challenge, even at the elementary level I was working at. So this article got me wondering how much accuracy is needed before computing a series beats pre-computed lookup tables and interpolation. Anyone got any relevant experience to share? How much accuracy does ray tracing require?
