Photon Soup Update

The die-hards kept running the program and we simulated 45.3 billion photons. The pictures are here. Thanks to all that helped out. I will be submitting the images to SIGGRAPH 2005 and a paper. (P.S. Never post your email address on slashdot. I got 900 emails! ouch.)"

  1. Crap server by Anonymous Coward · · Score: 1, Insightful

    You'd think that having a previous story on slashdot would kind of suggest getting a server that doesn't fall over because of the /. effect...

    Anybody got mirrors of the pics?

    I don't think he's computing the same scene as in 1993. It's likely much more complex. Also, more complex algorithms could be used. In other words, you can't really compare (with the data you have).

    who says the problem scales linear? maybe it's not O(n) but O(n*logn) or something.
    It pretty much has to scale linearly to be able to distribute it the way he's doing. Also, when you think about it, he's tracing the paths of photons and photons don't really interact with each other so therefore the complexity of the problem scales linearly with the number of photons.
