Q: Integration with GLFW

[mokiat]

Hi,

I came across this library and would like to plug it into some existing code of mine and get started with WebGPU coding.

My framework is already based on GLFW and I was wondering if there is a trivial way to get go-webgpu to work with GLFW?

I see that the examples use gamen, however, it does not support some of the features I need (e.g. gamepad input; drag & drop) and would also mean a more substantial rewrite.

Hey,

Sure you can use go-webgpu with glfw. The examples boids, cube, triangle and triangle-msaa use glfw. Each of these examples use pretty similar functionality from glfw.

The only quirky thing right now is that glfw doesn't have an extension for webgpu surface initialisation, so we have to do it manually and to do it cross platform way in Go we have to spread the surface creation across multiple go files. see:

• triangle/surface_darwin.go
• triangle/surface_wayland_linux.go
• triangle/surface_windows.go
• triangle/surface_x11_linux.go

Now that I think about it, go-webgpu repo can host a separate module that will have this helper function - meaning wgpu module will not depend on glfw; keeping things independent.

Hi! Thanks. I was looking at the wrong examples it seems. Sorry about that.

Having these functions available ready for use would be ideal. Aside from making it easy to get started with the library, if there are any issues in the future, they need only be fixed once.

Should I close this issue or will you be using it as reference for future work?

[rajveermalviya]

Closing it is fine. I'll mark it as answered

@mokiat I created wgpuext/glfw which provides the surface description creation helpers. Check out the examples for usage: boids, cube, triangle and triangle-msaa

@rajveermalviya , thanks. Just had a look and it works very nicely.
