So I have been asked to do a facade mapping, of a house roughly 20x20 m with one beamer. I haven’t done that before, and I had a look at the various threads here about that topic.
What would be a recommended workflow? As far as I understand, you guys create a 3D model (let’s say manually, or by lidar-scanning, or photogrammetry), and then manipulate that 3d-model in your 3d-modeling software, render it out, and project that onto the facade. Boom. Done.
But what’s the tricky part about that? How do you get the projectors real positions matched with your 3d-modeling softwares camera? And then, du you simply use homography to adjust the rendered video to the facade?
And what would be the vvvv-oriented workflow? Given, I have the 3d model, I would need to get a dead acurate projection-view-matrix for my renderer. I’ve been using rulr lately together with kinect to calibrate my projector, and it worked like a charm, but that won’t work at such a large scale.
This somehow is a scary project ;-)
