Abies Electronicus / Space Scanner
For those interested in technical stuff,
we used MadMapper’s Space Scanner feature to produce a 1to1 pixel map of the projectors,
which simply allowed us to map during the day, safely knowing that the mapping will fit the tree.
Here are the resulting scans, shot at 1/30s or 1/60s depending on the ambiant lighting,
f2.8, iso 800, manual focus, Jpeg quality small (no Raw), using a Canon 5D mark II.
We used 4 projectors, so we produced 4 scans.
