(As it turns out, I'm working through getting this to work with pbrt, which has been "interesting", even without a GUI involved, so I can imagine it's extra tricky with...

Please do reach out via email. This is partially a question for the publisher of the book; I don’t know off hand how translations are usually handled. I do, however,...

Changing this would end up flipping the normals of all triangles, which in turn would cause images to be quite different. Admittedly we haven't documented the expected vertex ordering, but...

I'm not sure what change you're suggesting. Is it to always create a leaf if nPrimitives

1. Won't be an option in pbrt-v4, but it will be an exercise in the book. :-) One issue is that there isn't a widely adopted image file format standard...

@KelSolaar yep, that seems like the leading contender at this point!

FWIW I've implemented Fichet et al's OpenEXR spectral encoding in pbrt-v4 and just pushed it to github.

The code is indeed wrong. :-(. I'm going to defer fixing this until pbrt-v4, however, since doing so can cause rendered images to change significantly.

Nice find--thanks. I think it's best to leave this unfixed for now, since changing it will change rendered images (and I suspect that many scenes have had a `ReverseOrientation` added...

There's no built-in functionality for that, but it should be straightforward to modify the system to add that capability. I think it should just work to, for example, update `SamplerIntegrator::camera`...
