Multi-Viewer 3D Displays (why the 3DS is a handheld divice)

I have been trying to make a, glasses free, multi-viewer 3D monitor (like the Nintendo 3DS, only 23 inch and multiple viewers), and it is much more tricky than it looks.
The parallax barrier cuts down the brightness exponentially based on the number of viewer (50% light cut to do 1 pair of eyes, 75% for 2), so with 2 viewers the screen is dim. But there is more, the resolution is not only cut by 1/4, a pixel is just as narrow, but I am adding a huge gap between them (some test subjects could not even tell what they were looking at)…
Lenticular lenses cost about $12 a foot, but none of the ones I got in the sampler pack line up with the pixels on any of the monitors, so I have to sacrifice even more horizontal resolution…
I gave up and started doing head tracking, but isolating individual eyes on that scale is just about impossible, so I wind up wasting 4X the resolution just to have enough margin for a single viewer…
And it still doesn’t isolate the eyes properly!!!
Now I have a 3D display (if you do not move faster than the head tracking can follow, and remain 2 to 3 1/2 feet from the monitor) that tracks your head, but will not respond to more than 1 viewer…
So I decided that when the head tracking detects more than one person, or if you move around too fast, the character (Tuba-Goose​) will get irritated and leave…
If I can get it to do that, I would consider it a hell of an achievement. And even watching this quasi-3D interface figure out where you are and adjust the perspective  to compensate (with a bit of a lag sometimes) is a little unsettling… Kind of like being eyeballed by a goose…

I can work with this, but I might still have to buy the 3D monitor, or at least the lens that is made for the 23 inch display…

Isadora Updates

Mark recently updated Isadora …
Check out the release notes.

It changes the ways that videos are assigned to the stage.

Myo to OSC

Hey there everyone.

Here is a video those missing steps of getting the Myo up and working:

And here are the links that you would need:

https://github.com/samyk/myo-osc for the Xcode project

https://www.myo.com/start/ for the Myo software

Remember, that this is a very similar process to getting the Kinect, or any number of other devices connected to your computer and Isadora.

Please let me know if you have any questions, or if you would like to borrow the Myo and try to do this yourself.

Best!

Coherence???

I was thinking we might want our scenes to be connected… I have a patch that turns on an outside night scene with crickets chirping and animal moving around in the woods… There is also a little parallax as the “performer” moves around in the space (the 33% X 50% piece of the stage before the performer triggers another patch/scene/whatever), but I could adapt it if we have a common vision…

The performer’s position is represented by the moving H (Vorizontal) and V (Vertical) readout. The numbers would not be visible in the projection.
The trigger position is in the lower left corner.

The “Sextant” and a patch that I was using to activate my Scene/Actor when the performer was in area 1

I am guessing the area’s range is 100 X 100 in both directions, so I divided it into 33/33/34 W and 50/50 H, and wrote a user actor to define area 1. This could be used to activate a scene or turn on/off projectors.

The red quantifies the H axis, blue the V, purple is the combined, and green is the output with a value.
