rbfx VS Veldrid

good engines for C++ that meet your requirements https://github.com/u3d-community/U3D https://github.com/rbfx/rbfx i highly recommend taking a look at rbfx, U3D doesn't have all the fancy features that rbfx has but deep down they are the same engine almost. They are forks of Urho3D, a mature engine that has existed from the year of 2011/2010.

Urho3D is dead. There is the U3D project which is essentially a maintenance fork made after the original project was taken over by a crazy Russian nationalist. There is also rbfx which is a progression fork that is working to make improvements such as to the PBR rendering pipeline, making it work with C# if desired, as well as rebuilding and improving the editor. The original Urho3D is soon to be even more dead than currently, since the discourse forum is set for archival and deactivation at 4:00 AM tomorrow morning.

Go to: https://github.com/rbfx/rbfx, they have a discord but IIRC it's basically just a CMake build so you flip the flags to say "WebGL" or "Emscripten" or w/e and CMake will basically tell you everything that's wrong.

If anyone is looking for a Unity alternative, the guys at rbfx are doing a great job revamping the old Urho3D codebase: https://github.com/rbfx/rbfx

It has good C# scripting support, a nice editor and modern rendering pipeline.

You could try Urho3D or its newer fork rbfx.

I use an engine called rbfx which is a fork of the Urho3D engine. A lot of it is just the fact that I've been using it for over a decade, so I am comfortable with it. I'm a programmer, not really comfortable with integrated editor engines such as Unity or Godot, and the easy C++ extensibility of the engine appeals to me. Plus it's decently powerful, and well supported on a lot of platforms (I build for Windows, WebGL, and very occasionally RPi for the most part) and is open source to satisfy that stubbornly libertarian side of my character.

I'd recommend Veldrid

So, for example, Veldrid, a low cross-platform graphics API-agnostic rendering and compute library for .NET, has its own bindings to provide different graphics backends. How were those created? Is it a completely manual process? are tools available? How are those maintained?

https://github.com/mellinoe/veldrid and https://github.com/dotnet/Silk.NET are nice wrappers around several graphic apis

Check out Veldrid.

Veldrid is a lower level engine that abstracts away a bunch of backends for you. Youll have to build your own pieces on top.

Also noteworthy: Veldrid

in addition to what everyone has said already, take a look at https://github.com/mellinoe/veldrid

Veldrid for graphics although I think SILK.net would also work well.

If you’re interested in C#, You could look into Veldrid. It is 3D however, so im not sure how easy it is to do 2D with it. ImGui.NET is a set of .NET bindings for Dear ImGui, which is one of the best immediate mode gui librarys out there imo. It has a canvas feature which allows you to draw 2D shapes via the gui renderer. Also, the creator of Veldrid and ImGui.NET has an example project for ImGui.NET using veldrid..

Veldrid attempts to wrap several graphics api, directx11, metal, opengl, and vulkan. You would have to write most things from scratch but this lib will work cross platform. Probably not consoles though.
