Polygon Project

I decided to ditch the stop motion for now and have some fun playing with video feedback instead. My little setup sketch from one of my previous posts turned out to be right - I will need two projectors and laptops for future tests because with this single projector setup, the actual feedback projected on the wall is blurred as it's focusing on the lines of the cube which is about two meters in front, and this will only be amplified with the bigger spaces involved at the warehouse.

This footage is all a bit samey, but in future tests I'll be able to control what's happening on the cube (or polygons) while hopefully somebody else will be able to help out with the camera work. It takes a while to get used to the ridiculously subtle camera movements that you need to be able to control the feedback, but it's so much fun when you get in the zone. Earlier footage was all over the place until I figured out the best positions to get into.

Mapping Feedback Test from Retchy on Vimeo

Apologies for the music, but I didn't want 6 minutes of silence. It makes it all seem so profound, doesn't it :)

I don't know where the green comes from by the way, it wasn't intentional. Maybe the projector was just slightly off balance and the extra green was amplified to infinity. And beyond. Or something.

Edit: I wasn't far off with that actually. Luka Dekleva wrote this on the Vimeo thread - 'Btw the green is probably a result of a colour temperature diference from projector to the camera. Green is 7200K (neonlight) Daylight is 5500K, and Tungsten is 3200K. you can see that your feedback is only gradualy becoming green. So the diference is acualy small maybe 500K (projector 6000K and camera 5500K) but it gets multiplied trough feedback.'

very nice blog, it's nice to see the process of projects in progress, especially about geometry and mapping..

Keep up the good work !
