[Radiance-general] 3D-360 video rendered with Radiance

[Mark Stock]

Folks,

I thought I'd let you know about my recently-completed 4-minute 3D-360
video that was rendered with Radiance. The subject is a dynamic
triangle mesh from a computational fluid dynamics simulation of a
sphere of fluid with a density discontinuity. (Lots of grey
cylinders.)

The original (2D rendering) video is here:

The new video (3D-360, for GearVR and other VR HMDs) is in multiple places:

I'll provide a direct download link for all you Radiance fans, who
know how hard this actually was:

The rendering took 8 months on a 4.4GHz, 8-core Intel Haswell chip.
Each original frame was 11520x11520 (in HDR, of course), but reduced
to 3840x3840 for storage, and further reduced to 3840x2160 for
publishing. In all, almost 1 Terapixel of primary rays were traced.
The directory takes up ~600 GB. I used an rcalc/rtrace trick to
generate the 3D-360 frames. The command line for each frame looked
like:

cnt 11520 11520 | rcalc -f 3d360.cal -e
"XD=11520;YD=11520;X=0;Y=0;Z=0;IPD=0.02;EX=0;EZ=0" | rtrace -ab 2 -aa
0 -ad 32 -as 0 -dj 0.7 -ds 0.06 -u+ -dv- -x 11520 -y 11520 -n 3 -fac
scene0695.oct > img_0695temp.pic

I attached the 3d360.cal file in case anyone else is interested.

Have fun, and good night!

Mark
