I knew I was going to be out of town for several days this week and wanted to
make sure my PC's processor time wasn't squandered while I was away. So, I set
up an experimental scene to do a series of progressively more detailed brute
force octree space partitioning renders, using sparse voxels to fill a Julia
fractal with spheres (just because). Here's a "contact sheet" of the resulting
frames.
I also made a full-res video of the various iteration levels and posted it on
Vimeo here: http://vimeo.com/35855241
Cheers,
Rob

any word on render time?

Well, actual /render/ time wasn't that bad, it was about 4 hours total for all
frames, and then only because I had radiosity settings cranked WAY up.
But the /parse/ time was murder (brute force and all, which is I why I waited
until I was out of town for several days ;). It was about 10 hours parsing for
the first 9 frames, and 70 hours parsing the final one (ouch!).
But, since I wrote the position & radius of each sphere to include files, the
parsing only had to be done once :)

It's very elegant.

Oh man, that is really neat!
Any chance you would be willing to post the source for that?
THanks,

Grrrr, my hard disk crashed last night, but here's what I have from my last
backup, from my first experiments a couple of weeks ago...

Note to self: "Start backing up your data every night!!!!!"
/grrr

Did you try putting it as slave into another computer? ...in my
experience, most of the times it is a boot sector problem, and the data
can be retrieved easily this way.
