    Hi Adam I choose optical because is more smooth, with the inertia of the bulb filaments the leds respond more slow if not the strobe effect I don't tolerate more than few minutes. But like this I can let them for hours.(but I have to change bulbs when they burn out):rolleyes: In the column I...

    Doubt the embroidery on the shirts would be accurate enough! But it's a fun idea in the abstract. Adam

    Actually that's exactly what I was thinking. :) I've seen a few videos on Youtube, but they were from well-financed content creators with lots of subscribers and millions of views on each of their videos. It definitely did not look easy. Curious how the assembly process went for you? Adam

    I haven't tried that one yet, but based on a quick peek it looks really nice. I've enjoyed Raw Data a great deal even though the setting isn't nearly as photo-realistic. First-person shooters are already well-represented in VR, but I'd like to see the technology used for other games. Imagine...

    yes I do. I'll have to find them or i'll just take new ones. It's not what you are thinking. It's functional in the sense all the parts are there but it's plastic. You turn the shaft by hand and the valves and such operate. no oil no gas.... I wanted to do a metal one that runs but never got...

    From the first link in the first post above: "No one seems to realize that the well-known "Rainbow Hologram" technique can also let you produce holograms which are not based on optical interference at all. This makes it possible for you to create holograms where the "interference fringes" are...

    buffo replied to a thread hand drawn hologram in Hologeekery
    I was completely unaware of the existence of scratch-holograms. This is really interesting! So how wide would the scratches be from the point of a compass needle as described in the first post? I would imagine they would be quite a bit wider than 30 microns at least.?. If so, then a laser...

    I agree whole heartedly with this. It's a shame that we only have stereoscopic displays because we'll always be limited by that. I halfway agree with this. The problem I see is that with VR, there needs to be so much more than just 3D visuals. The graphics are immersive and I will admit,...

    You mentioned buying used - have you checked the Facebook Laserist Group? Sometimes people post equipment for sale there. If you're thinking about buying new, you might want to have a look at the X-Laser Skywriter projectors. They come in 2 and 5 watt versions. (5 watt is the HPX Tour) ...

    Agreed, although I'm at a loss to come up with another solution for 3D apart from a stereoscopic display. While the idea of capturing an interference pattern in a hologram to create a true 3D image is sexy as hell, I can't fathom a technology that could create such an interference pattern in real...

    That's the bit I'm struggling with and wonder if it's why the original company folded. Why do you need a mat and a projector when you can simply project the whole game into a pair of VR glasses such as Pimax or Occulus? Maybe this is an attempt to produce a cheaper version of VR by using AR and...

    Unfortunately with "3D" there is really very little movement forward. It seems the industry is stuck at stereoscopic displays. That's the only game in town right now and has been for a long time. The only development is just perfecting was has already been the industry standard for decades. ...

    Not to dispute anyone here but I find the DMX features of Beyond and Quickshow very capable. I use Beyond exclusively for controlling my Halloween display ever year. DMX sequences can be programed with as many steps as you want, block changes between the steps or gradual. These sequences can be...

    Someone posted a while back about a small inflatable dome that you could use in your living room (seriously, like 2.5 meters - maybe smaller?), and if I remember correctly the use case involved a head-mounted pair of MEMS-projectors fed by a laser source. Coupled with the head-tracking 3D glasses...

    What you can do with the laser via DMX will depend on the capabilities of the built-in DMX control. While Beyond (and QuickShow?) can do DMX output, that's not really their main focus, so I wouldn't recommend it unless you're already using Beyond/QS for laser control. For dedicated DMX...
