@neauoire I have a question I suspect might be based on an ill-informed foundation.

But I am wondering, in your experience what kind of digital art consumes the least power?

Would it be pixel art? Or simple vector graphics?

@freedcreative Mhmm, I'm not sure, I don't think the style is so impactful. I can do 3d in moogle for longer on my computer than I can do pixelart in a html5 canvas.

@neauoire @freedcreative hmm, the efficiency of rendering code is what matters; but style is a factor in what rendering merhods will likely be used. e.g. neural network raytracing vs. bresenham.

the hardware is a factor too, an nes with ttl logic may consume many times more power trying to compute the same thing that takes a fraction of energy for a raspberry pi to compute

@zens @freedcreative so yeah, the platform is what matters most, the problem is now most low-energy platform always run high-octane inefficient software so..

@neauoire @zens I should give context.

I’m about to hook into teaching open creative software, and I’d also like to talk about shifting towards reducing power consumption too.

I was thinking one way might be, for example, teaching 1 bit pixel art via widely used, familiar software. Then showing how to use the same art techniques on low power software and hardware platforms.

So I was wondering if that’s the art style the best makes that jump.

@freedcreative @zens that's an excellent idea :) Maybe you could talk about emulation a bit!

@neauoire @zens I would love to.

I installed uxn for the first time this week, and I have a laptop that hasn’t been able to handle common computing tasks since I got it. Thought it might have finally found it’s purpose as a uxn host.

Seeing the pixel art you have produced on there is what made me think of this teaching approach.

@freedcreative @zens Have you tried noodle yet? It's designed for making 1bpp art :)

@neauoire @zens I haven’t yet but I plan to!

Step one was installing uxn last week, but my current setup is 4k so it was teeny tiny. That’s what made me think that laptop I’ve never been able use, but hated to discard or impose on someone else, might be my first sort-of salvage attempt.

It’s too weak to even handle basic web browsing properly, so uxn might make it useful 4 years after purchase!

@freedcreative @neauoire you could say that it is, with relation to low power displays like epaper, or that sharp memory display thing, or scientific calculators with z80 processors, green and black lcd displays and two aaa batteries last for months, possibly even on solar power

@freedcreative @neauoire my favourite is flipdot displays. clackclackclackclackclack

@freedcreative @neauoire intuitively it feels like retro tech and older art styles should consume less power, and that newer computers throw elecricity away on bloat and inefficient software, but I think we should always question our assumptions, and measure. a lot of that may be correct, or maybe hardware has become many times more efficient, but still consumes more power because it’d doing more.

I wonder if it’s possible to e.g. underclock a raspberry pi for lower power consumption

@zens @freedcreative Of course you can :) We throttle our devices so they suck on too much power, it makes them slower but it's worth it.

@neauoire @freedcreative back in the pthee lifetime when I homebrewed gameboy games, the gbc and gba had a “halt” instruction that would stop the CPU, and consequently use less energy- resuming on the event of an interrupt. in principle, if your game isn’t computationally intensive, you halt early to wait for the next frame and consume way less battery power.

on the other hand, many games instead do a “busy loop”, instead of halting at the end of a frame, a loop checks for some condition.

@neauoire @freedcreative this effectively puts the cpu at 100%, and consumes more power. a CPU with so called “static” memory and logic,is also able to go into a sleep mode, where the cpu is fully stopped and consumes zero energy, and is able to exactly resume when signaled

@neauoire @freedcreative a solar powered gameboy by <s>MIT</s> northwestern university of illinois heavily relied on this static halting concept retrorgb.com/solar-powered-gam

@neauoire @freedcreative combined with an epaper or memory display, non animated screens could potentially consume very little or no energy
