A friend of mine enquired a while back about helping her install some software to do video light painting. It got me thinking, and I just had to try making my own realtime version. This is the result of an evening playing with feedback and cache TOPs in TouchDesigner.
My laptop's webcam is pretty useless in low light, so the footage is super noisy, but you get the general idea. At some point I hope to get myself a capture card, borrow a fancy DSLR and revisit this project.
