I thought I was done with the sinewaves. But after a reminder from @Andrew_Tuline I gave them another go today. Why not describing lissajous functions in a 3dimensional space? Why not linking one to x, y and scale of a single noise plane? That looked already pretty funky. Next step: What happens if you apply several lissajous sets to several layers? Have a look!

The fine tuning here – the balance of all parameters becomes tricky. It is a thin line between good looking and chaotic flicker. I´m at a point where I would need a holographic projection to visualize all my variables and layers in realtime. If you try to adjust the parameters while watching the final merged animation it just drives you crazy – no chance to trace what is going when where and why wrong – the system simply has become to complex.
Well, mapping small 8x8 versions of the noise arrays onto the matrix is an work arround for now. The oscillator values I mapped with a different color semitransparent on the top of it…

Probably a good time to consider connecting several matrices to a Teensy in order to have a decent developing environment capable of visualizing all layers and data simultaneously.

I have so many ideas and it has become hard to explain or describe them even to myself – I just „see“ them and all I can do is to manifest (code) the visions immediately, otherwise they are lost. Good, that I have some free time at the moment…

NICE! It looks like it’s rotating :smiley:

Just 2 different layers shifted against each other create this illusion of a 3dimensional space. There is no particle system behind :wink:

Very nice, and SURREAL!

@ http://www.youtube.com/watch?v=L4uElKHFzbk&t=2m36s I love the combination of music and visuals

You should make a “montage” video showing the progression of your work over the last year!

That is a nice idea, Mark. But you know, before I can do this I need to write some REALLY good effects to have a proper ending of the video… :wink:
By the way, I thought about you today while considering the usage of your palettes. I think this is calculation-timewise the fastest solution for my “defined soft edges” problem.

Good idea Mark. Is this a series of light strips, or a pre-configured matrix? I’d love to see a montage!

It is a matrix like this one: http://www.ebay.de/itm/16-X-16-RGB-LED-Matrix-WS-2812-B-/111469594570?pt=Bauteile&hash=item19f41b07ca

I found these on Aliexpress last night — FYI around the 58 USD mark.

I was tempted to buy four — but then realised the edges are much wider than the pixel spacing

I just saw these 32x8 flexible-back matrices:


Now if only they were half that price… I would have ordered more than I did.

Lots of possibilities, nice pre-built rectangular matrix panel.

@James_Carruthers : There are no conducting tracks outside the leds beside to the capacitors - but they are in the same distance as the others. So what I am going to say is that I see no reason NOT to crop the panel down to a size alowing to string them together. (Sorry for my english, I just woke up…)
@Mark_Kriegsman Thanks for the link, they appear perfect to be mounted on a cylinder for projecting the pixels as with small distance to a wall as a long uplight.

Correction: at the upper and lower end are 2 tracks - the “serpentines” - but why not having the really thin “pcbs” overlapping in this area? It is still within the range of the led distance.

@Mark_Kriegsman Not a montage yet, but my youtube channel shows at least the progress I made within the last 6 month: https://www.youtube.com/channel/UCkOEj4gOrUq1rbKElkmdo9g
