Not sure I understand your requirement, but I do outdoor projections with
my 15k projector, I don't want to roll around with a ton of expensive
lenses (let alone purchase or rent them) so I basically stick to a short
and medium through then use a laptop to do what i call "cornerpinning"...
from across the street, i could use realtime position of the four corners
of video to properly fit video/images onto any size, and from very extreme
angles.
I pretty much overshoot, essentially ignoring the lensing (just making
sure I can get focus), then use cornerpinning to shrink, position, and
keystone the projection... down to any teeny tiny size I need.
ps: i use Isadora and an evolution ec33e midi controller for my
cornerpinning in case you're interested.
