glutin VS emacs-gl

Yeah, render Emacs via GPU. We get underlined display server opengl context using surfman or glutin. Since PGTK is gtk, we are using gl_area. Replaced the Cairo drawing with this Firefox's Webrender. Using this, you can except some improvements to rendering. However, I dont know how to do benchmarks regarding GUI rendering.

But I think this will be solved when I switch back the GL context creation to glutin (thankfully, version 0.30 will decouple from windows creation), and I rewrite sprite-render.

Hello, I'm a beginner rust dev trying to make a simple thingy in piston. I've got a picture to follow the mouse cursor, but when I try to hide the cursor with window.set_capture_cursor(true) , it seems like mouse events seize to exist. I found this bug report Mouse Grabbing and MouseMoved Event · Issue #696 · rust-windowing/glutin (github.com) , but that was resolved years ago. I'm using pistoncore-glutin_window = "0.70.1". Am I doing something wrong? If not, is there any other easy way to hide the cursor?

Luckily, there are quite a few libraries out there that provide this functionality, some of them specifically aimed at OpenGL. Those libraries save us all the operation-system specific work and give us a window and an OpenGL context to render in. One of those libraries is glutin. It allows us to create an OpenGL context, define window parameters, and handle user input, which is plenty enough for our purposes.

Yeah this is a known issue in VMs https://github.com/rust-windowing/glutin/blob/master/ISSUES.md but I haven't found a way to fix it. It does not even work with llvmpipe mesa, which provides the newest OpenGL drivers.

By the way, why only for pgtk? It would be nice to have it without pgtk or xwidgets (OpenGL was avaialable via xwidgets since quite some time, as a plugin).

If you need some 3D viz, there is also an Emacs binding to OpenGL. I believe it works only on X11, but I am not sure.

Webrender is using openGL. There are existing work out there regarding this. https://github.com/Jimx-/emacs-gl . But I would prefer WebGPU API over opengl's if I want to do computer graphics.

There is also a module to do OpenGL. You will have to compile the module yourself, but it shouldn't be too hard. No idea though how well, if at all, it works on macos.

Generally, librsvg (svg.el), is your best option to start with graphing in Emacs. Alternatively, if you are really ambitious you could take a look at Emacs-gl if you are familiar with OpenGL. Those are your drawing library. On top of them you will have to create some higher level library to draw charts, you could either adapt/convert one existing from some of other projects, for example there are several popular and good libraries for javascript that could probably work well with svg renderer. Perhaps take a look at some of Common Lisp charting libraries and see if you can make them work on top of svg.el or emacs-gl. For example, cl-2d seems quite reasonable to port to Emacs Lisp.
