The Sharpest, highest resolution full color volumetric display in existence! Check out our 3D printed Volmetric display at: volumetrics.co/ Prior work: thecriticaltec...
I was thinking about this concept for a few weeks before I bumped onto this video. I was thinking a high speed projector projecting vertically down on a spinning wavy surface might be more clear than this. Cool concept anyway. :-)
@@AndroidFerret Do you know anywhere the parts or plans for these are commercially available? The volumetrics company is defunct, having a hard time finding alternatives. I'm trying to commission the plans to be made, but I'm not sure about the arduino microctontroller.
To anyone reading this now in the future. A two photo diodes on the base should work, and put light on that spot every N frames. Then you can use the light shining on them to speed up or slow down the motor slightly. That could divide the frames outputted into separate layers.
Well i don't want to be the bearer of bad news but this is not really projecting 3d objects or shapes, based on this and other videos from this channel it looks like there is a common occurrence with the projected image being a long linear shape, but also seems like it has a fixed length problem (as in the projected shape always extends to the top and to the bottom of the spinning display), which implies that it can't produce a small shape in the middle of the screw or display, it might still be possible to achieve this with this current set up it has, but based on all the videos posted it seems they didn't show any update/demo of a moving object within the confines of the display. In conclusion, Like I said it is still possible to use this for actual 3d with just a few tweaks (as in placing a encoder synced with the projector).
Hi Michel, if i was to project more complex shapes using an fpga to process the images and control a motor, would a servo motor be best suited? (vs steppers, encoders, etc.)
WoW, you got better results grass hopper... i start to wonder what projector are you using that have such high speed. so your next task is getting away from the extrusion trick...but it looks nice...
Spin the helix synchronously with the projector and it'd be easy enough to change shape mid extrusion It does requires a new frame per vertical 'pixel' , 1080 vertical resolution = 64800 hz for 60fps video, bit of an ask for a commercial projector but well within the reach of current electronics
Hello David, I am really interested in this technology and I want to work on this, I am a student of computer science. It would be really great if you could get in touch with me to discuss some of the process like printing (projecting) the images etc. I'm really looking forward for your reply and help.
I am in the same boat. I want the info on that helix. How light can the helix be? Can we access the 3d print files from the helix. I have a pico projector I want to experiment with. I am an indie developer. Thanks for any info.
+ondrej buncek Hi, I get pretty good result with the machine, I actually find it one of the best I've worked with so far. If you want some best practice tips feel free to pay us a visit at our Berlin studio :)
