PyGL3Display - 1.9-alpha

David Griffin (habilain)



2.0 will be the final version of PyGL3Display

I've been looking through PyGL3Displays code with the intention of implementing proper Z-ordering and have come to the conclusion uncovered that a) PyGL3Display would likely need some major API-breaking work to implement Z-ordering in any sane manner and b) there's a fair amount of other use cases which PyGL3Display, in it's current form, simply cannot do (e.g. multiple windows)

Hence the choices are either a backwards incompatible release or to put PyGL3Display in maintenance only mode and move to another project. I've chosen the latter; apologies to anyone that this inconveniences. - David

PyGL3Display is a high performance, OpenGL, 2D sprite library for Python/Pygame with a simple API, not too dissimilar to Pygames (There's an API compatible Image object, and Sprites are not too dissimilar). It requires slightly more recent hardware than other libraries, but it is "breaks the Pygame FPS counter" fast*.

License: GPL v2 / v3. Commercial licenses are negotiable - at least on parts which I have copyright on (as I am open to outside contribution).

Requirements: Python 2.x, Pygame, PyOpenGL, OpenGL 2.0 compliant system

On Linux only: CFFI can replace PyOpenGL

Not yet compatible with Python 3

Main Design:

1. Near optimal performance.

2. Use GPU shaders as much as possible, as Python programs are much more likely to be CPU bound.

3. Clean, easy to use "normal" API, which also has an advanced mode for people who want the absolute maximum in performance and don't mind getting their hands dirty. For normal use, the API should not be any more difficult to use than Pygame.

* "Breaks the Pygame FPS counter" fast: On my Phenom II based system, the text demo, which draws a not inconsiderable amount of text, jumps between 3333.33 FPS and 5000 FPS according to a Pygame clock object. A hand written FPS counter indicates the real FPS is about 4200. On a much older system (Pentium 4), PyGL3Display still manages 666.66 FPS according to Pygame clocks - which again, seems like I'm hitting some accuracy limit in floating points.

Note: Questions, bug reports etc. are all best done through Launchpad, because that way I'll get notified quickly.


An Alpha release for people who want to use the library. It seems stable, but is not yet feature complete. That said, it's probably better than the old 1.1 version in all respects.

This is *exactly* what I've been looking for! Thank you!

TIP: 7-zip 9.20 can handle xz files ( XZ is listed as a supported format.

Right-clicking in Windows Exploder doesn't show "Open with" for 7z, but if you open 7z File Browser and access the archive file it works. Looks like a bug in the installer, not registering the mime type.

7zip can't open it :(

I'd love to give it a try, but I can't do anything with the downloaded file.
I'm running Windows 7.
