CYGN-B

[Greg]

Is the CYGN-B recognized as a unique enough piece of physics that a Dryer complete system must contain a non-emulated original CYGN-B circuit?


The 3D6B emulator is not a Dryer complete system. The constraint is eight max ADCs for live signal input.


So, for example, the individual gain pots on the 6b panel were an important part of the instrument. In 3D6B one sets punch in / out points for data modification, declares the joysticks as four individual gains, and then does a take.


It's like playing a live rock show by recording two guitar strings at a time, with editing capabilities. It sucks.


But perhaps it's not philosophically as cut and dried as that. The encoders and the 6B can be viewed as a single system requiring exactly one two person take and another one person live performance for the art proper to exist. So the take + performance idea is already there.


I'm developing toward choreography determined parameters dynamically applied to the joysticks so it's like the system hands you all the right dials to turn at the right times, and you get to keep your hands on the joysticks, and still do the live performance.


Two more good ideas noted:
1) A shorthand for the user interface design philosophy behind the 6B.


2) A "Dryer test" regarding performance. laserist and ronhip are among the very few people who could perform the calibration for the test.


Ron: Yes, thank you! Exactly the photos I was remembering. Do you still have access to the photos and slides you preserved? We'd love to see and discuss any photos of people, places, and or equipment you might care to post.


Steve: That circuit lesson sounded interesting. I love the fascinating insights into the theory and history underlying the development of radar that you always share.


Other notes:
Ramp Z is another 3D mode of Ivan space. Suggestions welcome.

on the definition of the Ivan space:


Multiple simultaneous points on a two dimensional plane can be described using a coordinate system. In Ivan space, the points are not independent of each other. Each point described as a vector or coordinate is transformed by a menu of gains, states and offsets, and by joystick positions.


As the result of the collaboration on this thread, an open live performance laser show development framework based on but not limited to an implementation of the Ivan space in C++ code exists. Ok it's not exactly "open".


In any case, an existing implementation in software should make a definition accessible.


In reply to the exploding message, incendiary comment follows. Please realize I'm mostly saying this for the jokes. No offense to anyone.

I want my content, what ever innovative imagery I might develop, to be able to resolve in a pullback to that stately orb of danubes, and have it look as genuine as possible. It's like ending a concert on a blues E. Back to where it all comes from can be a potent theatrical device.


In past discussion it was analogized joysticks vs. DAW to a pool of kids splashing around vs. synchronized swimming. I think this is a very good analogy. I find synchronized swimming dull, but it's all in the mind. Wiggle those joysticks and cymbals crash. Birds fly. Spaceships do ballet, and tornadoes have <censored>.


To scoff at non centering analog joysticks is to sneer at Cymbaline.

Greg,

Yes, I have access to the archive since, I guess, I'm the "archivist" having done all the digitization of images, videos and documents. Unfortunately I don't have a way to usefully put all that on-line. I don't own a digital Asset Management (DAM) system or have access to a public version anymore. But I do have all the assets and the associated metadata. I was looking into a DAM called "Daminion" (https://daminion.net/) but it only runs under Windows, and I don't think I want to take on running a Windows based machine (I'd much prefer MacOS or LINUX... Something I know...) Scott is still publishing videos to YouTube: https://www.youtube.com/@Laserium

About me and laserist being the only ones, there are others still around too. Remember, even though I did that wonderful show for 20 years, I haven't touched it since 1998 (28 years ago!!!), so I may a bit rusty, or completely rusted through!
