simple-game VS piet

I have a somewhat naive version of this sort of system running via wgpu, but that's likely lower level than you'd want to go.

I won't claim this is great code, but poke around a little bit at my wgpu code and get a sense for how it compares to OpenGL. Overall the concepts are pretty close to each other, it's just that you declare everything up front instead of poking at OpenGL via functions to set things to the state you want.

It's really not that bad. I had some complaints about WGSL a few months ago but it was surprising how quickly it improved. Here are some simple real-world shaders you can look at:

If you combine it with a quick build step to give you shader compilation errors before your program runs, it becomes a pretty nice shading language. There are still a few rough edges but it's not _that_ bad to work with.

Thanks! I ended up going that route here

You can even check https://github.com/linebender/piet and https://github.com/RazrFalcon/tiny-skia. They are pure rust libraries. Skia as a whole is a big binary to add.

First, at the deepest level, we are moving away from Piet, which is a cross-platform 2D graphics abstraction. Under the hood it uses whatever the standard OS API is. Instead we will be using Vello which we have been building as a research project for years already. It is starting to near its v0.1, which is very exciting. Fundamentally it is a novel GPU accelerated 2D rendering engine with a strong focus on performance. It is not ready for benchmarks yet, but we're confident it will deliver. If you're curious, you can check out the Vello roadmap for 2023.

you can use piet, although that is more of an abstraction over existing, platform-dependent libraries. So not really pure rust, but definitely cross-platform.

Piet is the backend for the Druid UI framework. It is indeed cross-platform. The SVG backend looks like it would work without an OS, but I'm not sure the value of a GUI toolkit without an OS anyway :)

Piet can render text. You can use Piet_common with the BitMapTarget to generate images Here is an example.

Piet (https://github.com/linebender/piet) should work.

So the 3 I'm looking at right now are 1. druid 1. piet 1. bevy

It relies on piet 2D graphic library; on Linux that means GTK/Cairo 2D primitives
