OpenFrameworks VS DiligentEngine

Not exactly VJ, but could be used for it. https://openframeworks.cc

Since you have C# experience, take this time to learn more about C++ while you continue to look. While yes, it is very easy to write bad code, it's not a huge deal since you just graduated and are just hacking around. Plus there are a lot of helpers these days to make writing bad code a little less likely.A former mentor of mine gifted me "C++ Without Fear" by Brian Overland which I can recommend. It's not too expensive, I think it was $25 or something like that, likely less used. Also comes in E-book form.If you'd like a gentler introduction to C++, may I recommend openFrameworks?

Have you come across openFrameworks (https://openframeworks.cc/) or Cinder (https://libcinder.org/)?

Not sure it checks all your boxes, but check openFrameworks?

I recently heard of openFrameworks which should make it pretty easy to make your game. It handles putting together a bunch of other libraries and window management so you can focus on drawing some shapes on the screen and handling user input. Sounds like love2d but all C++.

let me know if I can help out - also checkout the forum at openframeworks.cc - the people there are very friendly and helpful - especially with people that are completely new to oF...

I mean, https://www.libcinder.org and https://openframeworks.cc have been mainstays of the creative coding industry for a long time now. A Rust take on the problem shouldn't be too surprising.

Neither Apple nor Microsoft want any usable multiplatform graphics API. For this reason, none of them delivers such a thing.

If you want a multiplatform graphics API, you should use a library which implements such API on top of these native OS-specific APIs.

I have good experience with that one: http://diligentgraphics.com/diligent-engine/ I’ve used it couple times on Windows with D3D12 backend, and on Linux with GLES 3.1 backend.

Diligent Engine: They say their engine is the successor of bgfx, but I'm not rly into that topic.

Diligent Engine. A Modern Cross-Platform Low-Level 3D Graphics Library and Rendering Framework Tweet.

Read other people's code (I recommend modern small to medium sized github projects, because large ones can be overwhelming) or else you will forever stay in your bubble of how things are done. For example, I had learned a thing or two by using (and code browsing) diligent engine's source.

Diligent Engine

I'm not speaking out of my ass, either, I have very actively followed low-level development being done towards open-source engines such as Diligent and Wicked. I personally am a contributor to the latter engine, as well. It is baffling to me that independent developers don't support this platform.
