I found that 'Cardoid' scene would leak many rays into the inner box, and that in other scenes I was seeing occasional rays pass through lenses (via the circular part) unaffected.

I was able to resolve the issue by adding a normalise() into the unPackRay() func, i.e

  ...
  dir = normalize(dir);
  return Ray(pos, dir, 1.0/dir, sign(dir));
}

osx 10.11.1 - Intel HD Graphics 5000 - safari 9.01 (possibly a a symptom of the graphics card as an AMD based mac had no issue).

Thanks for a great tool!
It would be cool to see a Femto Photography example as part of this package.

First of all, this is a superb work, very beautiful.

I found something that looks like a small issue playing with it, though: in chrome, when selecting "cornell box", the right sphere seems in contact with the box on the lower end, and so some light rays escape the box. Perhaps it is not an issue but that the sphere is too low in the scene and overlaps with the box; but if they do not overlap, it might point to a rounding error of some sort.

Tried running this on windows, in chrome and firefox, and got this error in both. I was able to compile the shaders, so I don't think that is the issue. Am I supposed to use Mac/Linux to run this, or have you been able to run it on Windows?

First, thank you for this sharing. Would you please tell more detail about this?
