If use custom class for textures to store all pointers, id, name, gabage collector will not delete instances of such class and pointers will be not affected. Or I didnt understend the issue?
Some day I will lean how to load textured mesh with C#

Now only theory

Maybe anyone knows, how to use antialiasing with Silky.Nvg?
The heart image - it is the PNG texture which is 1000px in size, but rendered on screen in small size 100px and has visible jagged edges.

TechPizza•1/7/23, 4:43 PM

antialiasing won't be effective for images

flykeOP•1/7/23, 5:09 PM

I just want it look normal, smooth, the tecnical term is not important

Had same problem in UE and it solved by changes in texture settings.

TechPizza•1/7/23, 5:10 PM

hmm, linear instead of point clamp filtering maybe

Lyris the Kitori•1/7/23, 5:10 PM

you want to look for the sampling mode, antialiasing isn't applicable here

TTechPizza hmm, linear instead of point clamp filtering maybe

Lyris the Kitori•1/7/23, 5:10 PM

TechPizza•1/7/23, 5:11 PM

downscaling large textures (1000 to 100) won't be effective either

thrillis•1/7/23, 5:14 PM

Or make/get an svg heart

thrillis•1/7/23, 5:14 PM

Sidestep the problem

TechPizza•1/7/23, 5:15 PM

especially considering that they are using Silky.Nvg

The garbage collector has no bearing on cleaning up your graphics resources.

Redhacker2•1/7/23, 7:55 PM

The only exception to that is if you use a custom class that explicitly does so on garbage collection

flykeOP•1/7/23, 11:23 PM

What I want to get is on screenshot, using svg will not work in this case. Tried all flags on Nvg.createImage, but it all looks the same.

Lyris the Kitori•1/7/23, 11:23 PM

pngtree

TechPizza•1/7/23, 11:23 PM

why would svg not work

flykeOP•1/7/23, 11:25 PM

Because textures are in png, they are images. I have many assets similar type for game UI.

TechPizza•1/7/23, 11:28 PM

understandable. you may be able to set the filtering mode before rendering

TechPizza•1/7/23, 11:28 PM

or just clone silky.nvg and modify it to your needs

Redhacker2•1/7/23, 11:30 PM

Or you could just not use it for images like this

flykeOP•1/7/23, 11:30 PM

Found soulution fir Unity, and it said - use custom shader some kind of “alpha-cut off” for displaying UI, similar like shaders for transparent hairs. But this it too complicated, for person who barely knows how to load image

TechPizza•1/7/23, 11:30 PM

alpha cut-off is absolutely not what you want lol

Redhacker2•1/7/23, 11:30 PM

You just want a quad

Redhacker2•1/7/23, 11:30 PM

A textured quad

TechPizza•1/7/23, 11:31 PM

i'm surprised nvg doesn't have a way to change texture filtering mode :/

flykeOP•1/7/23, 11:41 PM

Just for “science” - Silky.Nvg is a wrpapper? Not real library? I cant modify how things rendered? For example add some effects using shaders from examples.

TechPizza•1/7/23, 11:43 PM

it is a implementation in c#, you can modify it however you like

TechPizza•1/7/23, 11:45 PM

oh would you look at thats, ImageFlags has a NearestNearest flag

TechPizza•1/7/23, 11:45 PM

so images are linear-filtered by default

TechPizza•1/7/23, 11:45 PM

maybe you should try generating mipmaps or just make those images smaller

flykeOP•1/7/23, 11:56 PM

Thanks, flags have no visual effect. Maybe I use it in wrong way. I set flag once when image loaded from path.

TechPizza•1/7/23, 11:57 PM

i don't think the filtering mode would help you when the image is being scaled 10 to 1

TechPizza•1/7/23, 11:58 PM

or the filtering mode is setup to not scale when going down, only when scaling up

Lyris the Kitori•1/8/23, 12:04 AM

you can also scale down the image in a photo editor to a reasonable size

flykeOP•1/8/23, 12:26 AM

Repeated my experiment with fresh head, and this works:
nvg.CreateImage(Src, ImageFlags.GenerateMimpas);nvg.CreateImage(Src, ImageFlags.GenerateMimpas);
Image has dark border, but not pixelated.

Lyris the Kitori•1/8/23, 12:27 AM

So much science just to display picture

LLyris the Kitori you can also scale down the image in a photo editor to a reasonable size

flykeOP•1/8/23, 12:46 AM

I tested with Photoshop, resized image to 100px - and pixelated effect gone.
Image displayed ok with default "0" flag. So it was just an issue with image loading.
For the average user this is out of logic, we're expecting bigger images will look better.

Aqua•1/8/23, 12:47 AM

you often have mixed results scaling down large images.
if you use linear interpolation with mipmapping though it can look pretty damn good

Aqua•1/8/23, 12:47 AM

but if you're using point interpolation with no mipmaps then it's gonna look pretty garbage

flykeOP•1/8/23, 12:49 AM

What type of "interpolation" should I choose for 2d textures? Image editors have multiple options, never thought they are important.

TechPizza•1/8/23, 12:50 AM

gpus are not good at filtering

TechPizza•1/8/23, 12:50 AM

that's why mipmaps exist

Aqua•1/8/23, 12:50 AM

bilinear is normally decent enough.
if you're using a image editor then cubic interpolation is the one I'd suggest

TechPizza•1/8/23, 12:50 AM

most image editors just have a "best quality" option

Aqua•1/8/23, 12:51 AM

really? both the ones I use allow you to specify the exact interpolation type to use

TechPizza•1/8/23, 12:53 AM

by "just" i didn't mean only one :)

Aqua•1/8/23, 12:54 AM

TechPizza•1/8/23, 12:54 AM

paint.net is pretty good

Aqua•1/8/23, 12:55 AM

the heck is fant lmao
