Effectively, you have a 32 high x 1024×1024 cylinder. I mean, you can clearly see IN THE VIDEO, multiple words all over the inner and outer track. As long as the LED can switch very quickly, you can have an effective resolution of something much much higher (persistence of vision relies on seeing something that isn’t there any more – the LED doesn’t have to and normally doesn’t display a pixel for very long. Remember, the blade is MOVING along the rotational axis. Instead of calling them drawbacks, I’d say this project is incredibly cool already, and that I can’t wait to see what else this guy will come up with! You’re really stretching to invent this as a problem. Plus, there are a lot of potential ways to deal with noise issues: airfoils to wrap the blades, for example, or a glass case. Here’s the short list: you probably won’t want it running in a sleep clinic, a church, or during a violin recital none of which are on the short list of clients with business needs for purchasing volumetric 3D displays. You also claim noise will be a problem, but somehow conveniently neglect to say which environments that will be a problem in. It’s already good enough to prove his ideas are sound. If the timing isn’t good enough for what he’s trying to display today, he can solve that easily by using faster processors. Polar mathematical transformations solved that problem long before the advent of digital computers – it’s just a matter of applying some well understood math to the timing. You claim that “curved space” will be some kind of a problem with insurmountable distortion issues. Motion blur will help trick your eyes into ignoring the lack of detail. 32 pixels would be good enough for indicating layers: a car could drive in circles around a building, and although the car wouldn’t be rendered in HD quality, you’d still see the ideas. Well then let the disagreements begin! You claim that 32 pixels won’t be enough depth. Another way of limiting noise would be to use a very thick dome, but that would make it heavy and expensive, and would also limit cooling. Noise: This type of display is going to be very noisy unless you vacuum pump the dome, but then you probably won’t be able to get rid of the heat. It could theoretically be possible to build models that take this into consideration, but not with only 32 pixels of resolution. Being 3D there is no way this display could avoid this problem. The ones that weren’t would display distorted graphics since the inner edge of the display would be shorter than the outer edge. Resolution: The resolution seems to be 32x32x1024 pixels, you can not really display anything complex with only 32 pixels in two of the dimensions.Ĭurved space: These displays were usually made with the LEDs mounted on a PCB strip oriented the same as the spinning axle. But enough history, let’s talk drawbacks:įixed video memory: the onboard flash memory suggests that it will not be able to play back live generated video such as games. 3D versions have been discussed, but until recently small volume production of such a thing would have been expensive. This is a very old idea, the rotary POV displays were very popular advertisement displays in the 80s and 90s. Posted in LED Hacks Tagged POV display, viSio, volumen Post navigation So if there are any university coordinators in our midst - let’s get these guys some support! Today, and are finishing up a mechatronic engineering degree in Vienna, and are hoping to receive a grant to continue their studies abroad. You have to see the video of this thing in action. It’s an incredible project that started when he was only 16 years old. In total there are 1024 high power RGB LEDs, which draw a whopping 200W at full load, making it bright, crisp and visible even in direct sunlight. The new and improved VoLumen features 34 micro-controllers, each with 512MB flash memory for storing animation data. He’s been designing these Volumetric 3D displays for about 3 years now, with the first iteration called the viSio, capable of 40 fps 3D video without the need for any 3D glasses. As it turns out, the reason he built The Ripper was to aid in the manufacture of his VoLumen project. We recently shared one of other projects, The Ripper CNC Machine. It’s a stacked Persistance of Vision display, with 9 layers - effectively creating a Volumetric 3D POV Display. We’re just blown away by this new project by and.
