Hi Nicolas, I haven't tried your glipy terminal, but it looks very interesting. The main issue with an OpenGL backend for MPL is simply that a naive implementation is going to look ugly when compared, pixel-by-pixel, against the Agg or cairo backends to generate bitmaps. Agg and cairo are very good at drawing anti-aliased lines, whereas one must jump through hoops to get consumer OpenGL cards to render lines well. Here's an idea -- an OpenGLAgg backend that actually uses Agg for all the rendering, but blits the results to an OpenGL texture for display. Thus, the backend would really just be glue between the existing Agg backend and pyglet. -Andrew ------------------------------------------------------------------------------ This SF.net email is sponsored by: High Quality Requirements in a Collaborative Environment.
