Gotta go fast #1

Open Magnogen opened 2 years ago

It just takes way too long, especially at high(ish) resolutions like 2K.

Loading new canvas sizes also takes a while

Split it up and only computer smaller imagedatas at a time
Maybe make it into a shader (thanks for the idea, Xima)
Workers? idk research this...
Also only make it recompute when it needs to (currently its always rendering, even if the parameters don't change at all)

Alright, done the first one - the image is now split up into configurable chunks. This makes a nice mosaic effect when constantly changing the network values.

I'll have to fix a few bugs, I'll make issues for em and link here.

Got started on the last one too, most of the way there, just gotta fix the bugs I mentioned.

As for the shader and webworker ideas, I have no idea how to start that so ig I'll just do some glsl research and such, but tbh I quite like the rendering animation anyway, so we'll see how it goes

This is an excellent video - definitely look into using workers and typed arrays for speeding this up. The chunking I already have would definitely help too as each worker can just pass the chunked typed array back and the main thread can render it.

ARRAY BUFFERS

Saw this on twitter - might be worth looking into it tbh, a potential 3-4x boost in speed? Interesting.

Edit: Just did this with Camaker - SO FAST

Interesting, this might be a further stretch, but could be worth it. Idk
