Anti-alias

[A-man]

I read in this tutorial that anti-aliasing in raytracing is done by rendering to 2x the resolution and scaling it down to get an average around the edges. Is this the method Luxrender uses? It seems very inefficient, but perhaps necessary.

Is this the method Luxrender uses?

Nope, that method is extremely oooold-school and produced extremely baaaad results in many cases

Nowdays it may still be used in some Real-Time Ray Tracing application.

Chapter 7 of PBRT Book explains how Lux works: http://graphics.stanford.edu/~mmp/chapt ... apter7.pdf
