[matplotlib-devel] Qt OpenGL Backend

[Rowland, J (James)]

Hello

 

I have made a small Qt3 / OpenGL backend which we use
for fast animated plots. It depends on PyOpenGL and a tiny SWIG wrapping of
FTGL (texture mapped FreeType fonts). Using GL directly seemed the quickest way
to get high framerates on large displays. I understand the concerns about a
proliferation of unsupported backends (with no image support, sorry), but if anyone
is interested is there anywhere to upload this where other people could have a
look?

 

Cheers


James

Its only 6 sliders and a reset button. I suggested it because it seemed like 
such a simple task that would be natural to handle with the backends native 
widgets.

When Qt-4 came out, someone contributed a partially complete backend and I 
finished it because I wanted to use it.

Is there any objection to my replacing the SubplotTool with native widgets for 
the Qt4 backend? The SubplotTool isn't working there anyway. I'll drop the 
subject as far as the other backends are concerned.
