Hi.
I just wanna share a experiment.
I made a 3 weeks exercise with my students from first year course in architecture school..... based in renaissance drawing camera.
They had to design, draw , and build this device...for drawing purposes in the next level of the exercise.
It's A little different of pinhole camera experiments because, a glass lens is present, and the light reflects in a mirror, and finally the image appears in a translucent surface (paper in reality) over a transparent glass(not present in this images)
Some of them knows sketchup and share to me his models...and, I try in max/octane, to see what happens....the lens is not exactly the same, I just play with a deformed half sphere, and IOR values in specular material ...and adjust the focal length.

Wow, thats fascinating that the materials in Octane are able to reproduce the same physical effect you'd expect in real-world to this degree. Makes me wonder about possibly bouncing light off multiple mirrors to create an effect like something out of a lost temple in indiana jones or something.

Like this? Playing with Specular Depth adjusts the number of reflections...

if we talk 'bout that scene where light ray was bounced from the mirrors.. well, You ain't gonna do it =) Think myth buster tried to replicate that with real world object without Hollywood cheating & failed greatly =)

Nice test Perro! =)

The method of bouncing light off of multiple mirrors is definitely possible. You can even see the effect i'm talking about in the mytbusters episode you mention:


And thats all I was thinking of would be possible; bouncing a visible beam of light off of multiple mirrors.
