But, there are always problems that unveil themselves along the way.Īfter getting the masking completed properly, I realized that I had to tweak some aspects of the graphics and the interaction. It is super exciting to see this project gel more and more. It also feel fabulous to translate one’s ideas into actions and results. This was a fun bump to work through, considering my absorption over the last few days of projection mapping. Next step: connecting the latest Processing code of graphical animation, then connecting the blob tracking code with Max.Īt this point, I realized that I had to take individual masks and composite them to one image to invert, as a result of having localized graphics. I was able to connect Processing with Madmapper and to projection map the output of Processing on the fibers (image above). I made a Processing sketch that changes color over time. I threw together a super simple app to test things, before plugging in the real content. A simple Processing sketch which changes color over time. It’s critical to have mini steps along the way to trouble shoot and to get things right. I was excited, despite it being still far away from the finished piece. So after a few days of translating, I finally got this image. This took a bit longer than I expected, but was a fun exercise in being thrown into a new environment and getting things to fly. I switched to Madmapper.Įven though I have worked with Madmapper before, I had to sit with it for quite a bit to translate what I wanted to do, with how the software worked. I am concerned about processor intensity as the piece will have many processes running at once (interaction software, graphical animation, sound, network traffic display….). After playing around with VPT for a bit, it seemed to have a few extra steps and be quite processor heavy on my laptop. I started pulling the projection mapping with VPT and a rough setup in my studio using the knitted prototypes. I have also worked with VPT and used it with my students several times. I took a projection mapping workshop through CHiKA several years ago using Madmapper and modul8. With a depth camera scan, I can use that scan and isolate where the graphics are to appear. ![]() They can also do this in realtime, as I use this to detect where people are in the space at any given moment. Depth cameras take a scan of a space (often using infrared light/projections), noting not only x and y coordinates, but also z coordinates. The dawn of depth cameras accelerated this field. ![]() You define where the projection will go and confine it to that area. The projected image will not spill out to the outer space or the room. With projection mapping, you can project an image onto a surface, and only have the image upon the surface. The defined mechanical nature of hardware never fitted with the conceptual vision. I am going for an organic look, similar to what sailors refer to as milky seas caused by the luminous bacteria Vibrio harveyi, living in association with microalgal blooms. ![]() ![]() Both take away from the magic and etherealness that I am after. Considering the scale that I envision this piece, using hardware would require scads of wires and connections that signify either a lot of labor or manufacturing or some kind. This rules out LEDs (even the sewable and flexible ones). I am after a light that has minimal visual supports (ie hardware, wires, etc), and is light weight and soft (ie, flexible). I am seeking a field of light, a cloud or disbursement of light. I do not want visible individual lights nor hardware. I am not looking for a glow from within the fibers. While I have made other pieces that utilize that hardware (which has come a loooong way in recent years), such as Transmissions From The System, Memory Capsules, among others, it’s not the look that I am seeking. I’ve worked with all sorts of hardware for previous projects from incandescent bulbs to LEDs. Since then, I’ve looked into numerous ways to accomplish this. The vision that has been consistent throughout this odyssey, is glowing soft fiber structures.
