Rounding out this current crop of interactive diagrams, I’ve put some more together to teach my class various things about ray tracing, including tracing rays to cylinders, how light intensity drops off with distance, creating fog, and intersecting shapes.
This time I’ve really tried to push for more variety in the interactive diagrams, to see if I could create different kinds of looks and ways of interacting. It’s a huge space to explore, but I’m having fun exploring it! Click on the image below to see the latest crop:
One of the earliest computer images with the fog effect was “Foggy Chessman” by Weimer & Whitted:

I heard a story that when getting this image ready for publication, the very back of the model was cropped off by a bug. The “fog” was a hastily devised work-around for hiding the bug.
Yes, the question of who actually first invented the uniform fog effect is sort of a gray area,. Much of the back story has been lost in the mists of time. 😉
