Pygfx' purpose is to bring powerful and reliable visualization to the Python world. ๐
Pygfx (pronounced "py-graphics") is built on wgpu, enabling superior performance and reliability compared to OpenGL-based solutions. It is designed for simplicity and versatility: with its modular architecture, you can effortlessly assemble graphical scenes for diverse applications, from scientific visualization to video game rendering.

pip install -U pygfx glfw
To work correctly, pygfx needs some window to render to. Glfw is one
lightweight option, but there are others, too. If you use a different
wgpu-compatible window manager or only render offscreen you may choose to omit
glfw. Examples of alternatives include: jupyter_rfb
(rendering in Jupyter),
PyQt
, PySide
, or wx
.
In addition there are some platform
requirements, see the wgpu docs. In
essence, you need modern (enough) graphics drivers, and pip>=20.3
.
We're currently working towards version 1.0
, which means that the API
can change with each version. We expect to reach 1.0
near the end of
2024, at which point we start caring about backwards compatibility.
This means that until then, you should probably pin the pygfx version that you're using, and check the release notes when you update.
Note The example below is designed against the
main
branch, and may not work on the latest release from pypi, while we're in beta.
Note A walkthrough of this example can be found in the guide.
import pygfx as gfx
import pylinalg as la
cube = gfx.Mesh(
gfx.box_geometry(200, 200, 200),
gfx.MeshPhongMaterial(color="#336699"),
)
rot = la.quat_from_euler((0, 0.01), order="XY")
def animate():
cube.local.rotation = la.quat_mul(rot, cube.local.rotation)
if __name__ == "__main__":
gfx.show(cube, before_render=animate)
Some of pygfx's key features are:
- SDF based text rendering (example)
- order-independent transparency (OIT) (example)
- lights, shadows, and physically based rendering (PBR) (example)
- event system with built-in picking (example)
- texture and color mapping supporting 1D, 2D and 3D data (example)
And many more! Check out our feature demos in the docs.

To get a working dev install of pygfx you can use the following steps:
# Click the Fork button on GitHub and navigate to your fork
git clone <address_of_your_fork>
cd pygfx
# if you use a venv, create and activate it
pip install -e ".[dev,docs,examples]"
pytest tests
The test suite is divided into two parts; unit tests for the core, and unit tests for the examples.
pytest -v tests
runs the core unit tests.pytest -v examples
tests the examples.
