On: Deciphering the Business Card Raytracer

FWIW I was not able to open it with Preview on OS X 10.8

Eep, my mistake. You're right: it doesn't work. I thought I used to open PPMs with Preview back in Mac OS 10.3 or something else ancient. I could be mistaken on that.

Oh well. Everyone has Gimp and LibreOffice installed though, right? They both open the file without problems.

Graphic Converter can open PPMs, and that used to ship with every Mac. That's probably what you used.

Or just install ImageMagick, and do 'convert card.ppm card.png'.

If you have IM, just use 'display' to open it directly.

Ah. LibreOffice's Drawing program opened it. Thanks :)
