Right. In a longer term, i think OpenGL is a way to go, to get access to hardware-accelerated renderer. It is , however a lot more work comparing to providing thin layer on top of existing vector-graphics library, because OpenGL operates with much more primitive entities: triangles. > Anyway, we still have some other stuff to do before: > > - finish athens (including new text model) > - finish bridge > - test same with linux, windows > etc. > > On Apr 17, 2013, at 7:50 AM, Denis Kudriashov <dionisi...@gmail.com> wrote: > > Hi > > 2013/4/17 Fernando Olivero <fernando.oliv...@usi.ch> >> >> NICE work Esteban! >> >> Does the AthensQuartzSurface, support all Athens related code?
