[LOGGED] Aliasing w/LINES actor and glitches w/Live Draw

ckim

@dusx even with the bg size connected, the GPU Lines look jankier. The CPU Lines is too heavy/inefficient to be of use but sure looks cleaner/prettier!

I can see a difference also with a similar patch as DusX

here a screenshot detail of the lines:

you can see the white line (GPU) is not so clean as the yellow one.

and a screenshot with the zoom from projectors to 400:

This is a known issue. It happens when you make a small, tiny direction reversal (like quickly going a little bit up then immediately going a little bit down). It's a problem that has to be solved with changes to the code.

Can we expect an improvement soon?

Just so you can see how the aliasing is playing out, take a look at all these edges:
Would be awesome to be able to get a cleaner image.

In all honesty, this improvement will likely not be coming soon. There are more important features to core functionalities of the program in the works right now, and side-stepping those in order to improve something solely in the Live Drawing actor would only benefit our users that utilize the Live Drawing actor, (whereas the core changes we're looking at are aimed at making improvements that will benefit as much of the userbase as possible). We wish we had enough capital to hire an army of programmers who could help us improve everything about the software as quickly as possible and to implement feature requests immediately but unfortunately, we don't have those resources so we need to be very deliberate about what areas and features we spend time on developing.

Sorry, probably not the answer you wanted to hear, (and it's not the answer we want to give either), but for now we have to focus on other things.

Best wishes,

Whoa that's gorgeous!

This problem with the Lines vs the Classic Lines actor is something we'll definately investigate.

@woland

it is OK. Unfortunately I am not able to program so I could help.

@woland Thank you! Flag me down when you figure it out

as it happens, i love those spiky glitches. something similar popped up in a patch i made years ago - long before Live Drawing actor was a thing. i have no idea where these lines came from, but i tend to embrace glitches like this:

if you manage to fix the Live Drawing code, it would be lovely if there was a way to select glitch or non-glitch variants.

@dbini "To glitch or not to glitch..."

@woland Circling back around to the aliasing LINES actor problem and sending an oh-so-friendly-nudge to see if it might be possible to address? I would put it to good use immediately xxxxxxxxxxxxxxxxxxxxxxxC

@ckim

Unfortunately we're still dealing with other new features and addressing different bugs at the moment, but in the meantime, a workaround might be to use the lovely, free drawing program Alchemy and the Screen Capture actor to get that back into Isadora (I've used this method for a performance before and was very pleased with the result).

Best wishes,

Woland
