Looks very nice!!!! I'm wondering, since SDL is used, does that mean Librend
can only open one window?

I had planned to use SDL/OpenGL for my current application, but have switched to
FreeGLUT since it allows multiple windows.

GLUT is a better fitfor multiple windows but sadly its input handling is less than stellar:/There still are remains of the old GLUT backend there, I suppose itmight work with some tweaking. Another possibility would be to write aGTK/QT backend to manage the input and provide OpenGL context. Mightbe a worthwhile goal to pursue for the next version..-Ilmari

Ah, rats. Hmm. Is it that it responds poorly/sluggisly to input? Or
inconvenient API for getting events? (or...?)

Cool, I wasn't/am not yet familiar with GTK - just did a web search and
found: GtkGLExt http://gtkglext.source...

Looks nice, I'll have to try it out. (Cool, there seem to already be Ruby
bindings: http://ruby-gnome2.sourceforge.jp/hiki.cgi?G... )

Or> inconvenient API for getting events? (or...?)The last time i checked (a year or so ago (or was it three...)), itdidn't have mousewheel support (on win, linux version seemed to havemousebuttons 4 and 5) and there wasn't a real Windows installer. Theevent API is a bit of a pain as well, with all the events going toseparately set callbacks, instead of a single event pipe. Anyhow, it'sbeen a while since I last used it, so take this with a grain of salt -maybe things are better nowadays.Apart from that, it's a pretty good and easy to use system.-Ilmari
