Dear Gabriel,
This sounds like a really useful addition. Perhaps you could
steal^H^H^H^Hborrow someone else's code to make your life considerably
easier? Agg has a reputation for being a really great 2D bitmap
drawing kit in C++, and perhaps we could even use matplotlib's Python
binding. I don't know too much more about other toolkits, but I think
there's also an open-source implementation of the Quartz API. IIRC,
this is the kiva part of the chaco/scipy toolkit.
I guess speed could be critical in some cases (I can easily forsee
wanting to render into a texture object in realtime), so it might be
prudent to benchmark any potential libraries before doing any heavy
lifting.
I'd be happy to work with you to get this incorporated, although my own
time for implementation is pretty limited.
Cheers!
Andrew

Hello,
I'm interested in using standard QuickDraw-like drawing functions
(such as PaintArc() or PaintRect()) while still maintaing VisionEgg's
nice object stimulus model. It's quite easy to go down to the PyGame
level and just do it in straight OpenGL, but I'd sacrifice the ability
to easily add new stimuli to arbitrary viewports, in addition to many
other (great!) VisionEgg benefits.
The closest analogue in the default libs is the MoreStimuli module,
particularly Target2D(). In the hopes of delaying creating my own
module in this vein, essentially mimicking the QuickDraw/GDI functions
that I need, I was wondering if anybody's played around with making
such a library for VisionEgg.
Not a particularly difficult task, but quite time-consuming.
Thanks!
