Here are some clips of how the Light Blade ended up turning out. The arduino controlled the motor and the Led strip to create the color patterns. I then had a webcam connected to my laptop which captured a live video feed and additively built up the frames to create a long exposure effect. The video effect was programmed and run in Unity and then projected. I tried placing the projection next to and directly on the blade and ended up liking how the side by side looked better.
Overall, I'm happy with the overall result of the project but there are elements that I initially wanted but wasn't able to complete in a reasonable amount of time. There are a few things I'd like to improve when I get time to work on this again. First, is getting a better camera input because the webcam resolution and frame rate weren't great. Second, I'd like to be able to create representational images with the blade by sending data to the blade. I tried this but the data transfer was far to slow and didn't create a very compelling piece. I'll need to look into faster ways of sending data to the leds and potentially use something other than an Arduino to control the strip. Lastly, the additive effect runs at a decent frame rate currently but I think by using shaders and the GPU I could faster and better looking results.
