Tinkernut posted another tutorial video w/ VPT on Halloween projection mapping. VPT is a free tool for basic projection mapping, and it’s the price of free! Check out the original VPT tutorial by Tinkernut here.
P.s. if you are looking for a good projector for starting out with projection mapping, check out our article here. (The one in the tutorial is cheap, but only 320×240 resolution and 400 lumens).
