      @mhorga_ Nice, I just finished reading the first volume and writing a tracer in Swift. Very fun exercise!

      @warrenm how did you solve the slowness when sampling (ns = 100) the color to get rid of aliasing? as is, it’s O(N^3) which is not too good!

      @mhorga_ I didn’t; I cranked down the count when testing, then turned it back up to reduce the noise when I wanted to make nice renders.

      @warrenm it would be so great if we can make raytracing a bit faster by improving the cubic runtimes. maybe we can think of some Metal way 🤓

      @mhorga_ Acceleration structures like BVH help out enormously, and are covered in volume two.
