Pygfx

• wgpu-py

  7 468 9.1 Python

  WebGPU for Python

  

  Sorry, I'll try to be clearer. QRhi docs[1] say "The Qt Rendering Hardware Interface is an abstraction for hardware accelerated graphics APIs, such as, OpenGL, OpenGL ES, Direct3D, Metal, and Vulkan." And PySide6 includes a (python) wrapper for QRhi[2]. Meanwhile, pygfx builds on wgpu-py[3] which builds on wgpu[4] which is a "is a cross-platform, safe, pure-rust graphics API. It runs natively on Vulkan, Metal, D3D12, and OpenGL".

  So, from the standpoint of someone using PySide6, QRhi and pygfx seem to be alternative paths to the exact same underlying graphics APIs.

  Thus my question: How do they compare? How should I make an informed comparison between them?

• xgpu

  1 2 8.1 Python

  WebGPU (webgpu.h) Python bindings

  https://pypi.org/search/?q=wgpu

  Looks like xgpu is where it's actually at.

  xgpu: https://github.com/pyrym/xgpu :

  > xgpu is an aggressively typed, red-squiggle-free Python binding of wgpu-native, autogenerated from the upstream C headers

  wgpu-py has a conda-forge package: https://anaconda.org/conda-forge/wgpu-py

• fastplotlib

  3 413 8.9 Python

  Next-gen fast plotting library running on WGPU using the pygfx rendering engine

  

  Apart from being based on wgpu, Pygfx also has a better design IMO. Korijn deserves the credit for this. It's inspired by ThreeJS, based on the idea to keep things modular.

  We deliberately don't try to create an API that allows you to write visualizations with as few lines as possible. We focus on a flexible generic API instead, even if it's sometimes a bit verbose.

  We leave it up to others to create higher level (domain specific) APIs. Fastplotlib is one example: https://github.com/fastplotlib/fastplotlib

  QRhi is pretty much the exact same goal than pygfx with a different implementation: https://github.com/qt/qtbase/tree/dev/src/gui/rhi

• colour-visuals

  1 34 6.5 Python

  WebGPU-based visuals for colour science applications

  

  Pygfx is awesome!

  For years, we have looked at something solid to be able to implement 3D colour science visualisation. We used Vispy, but encountered some issues when interacting with the scenegraph, then a quick stint with Three.js which required doing dirty things to pass Python data to Javascript, and finally, Pygfx is the one that enabled us to do what we wanted: https://github.com/colour-science/colour-visuals
