webrtc-unreliable VS msdfgen

The Cargo.toml on GitHub has the optional dependency specified correctly.

I use WebRTC for multiplayer, and Rust has a great library (webrtc-unreliable) To be fair, C++ has libdatachannel which I like using too.

You can, in theory, get UDP-like characteristics out of a different web API - with a WebRTC datachannel configured to be unreliable and unordered. I haven't seen anybody use that API just because it's a pretty big pain to use. The developer of Agar IO called it too hard to use in a HackerNews comment, but nowadays there's simpler libraries than the ones he had in 2016 like webrtc-unreliable and libdatachannel. You still need to run a STUN/TURN server and the integration is easier than it was back then, but still much harder than raw UDP sockets though.

webrtc-unreliable: Provides an async API to a UDP-like transport over WebRTC

You can do this today with https://github.com/kyren/webrtc-unreliable

Take a look at webrtc-unreliable. I haven't tried it, but it claims to implement just a simple subset of webrtc to get udp-like functionality.

This very well explained here https://github.com/Chlumsky/msdfgen and with more details in link d pdf.

Basically, signed distance fields allow high resolution renders from low resolution rasters which represent character shape.

No idea how to help you but I will just drop this since it improved the quality for me by 1000 https://github.com/Chlumsky/msdfgen

And that's the complicated state of the art version for 3D perspective. Other versions are even simpler.

This is known as a “multi-channel signed distance field”, or “msdf”.

I use this, free and has been very good for me https://github.com/Chlumsky/msdfgen

Distance fields are not slow to render. They don't need a powerful gpu. Valve was already using SDF for textures in 2007 and released a paper about it. MSDF (multi channel signed distance fields) is a popular text libraries for game engine devs that uses distance fields. Distance fields are fast to render in 2D and even 3D. The problem is with everything around it. Lighting, shadows, shading will all require specialized tooling and likely a specialized engine for very little benefit (imo).

Signed distance fields only work well for relatively simple characters.

If you have highly detailed characters like Chinese or emojis, you need larger resolution to faithfully represent every detail. One way to get around excessive memory requirements is to store the characters in their default vector forms and only render the required characters on demand, but then you might as well render them at the required pixel resolution and do away with the additional complexity of SDF rendering.

SDFs are still useful though if you have to render text at many different resolutions, for example on signs in computer games, as seen in the original paper https://steamcdn-a.akamaihd.net/apps/valve/2007/SIGGRAPH2007...

In the past, SDFs also had problems with sharp corners, which has been solved in https://github.com/Chlumsky/msdfgen

MSDFGen looks pretty sweet. https://github.com/Chlumsky/msdfgen
