Dear All,
I've stumbled on this yesterday evening: "The function beginGL() does not exist.", while trying to switch a sketch from 1.5.1 to 2.0b6 (tried it now with 2.0b7, still doesn't work).
Minimal sketch reproducing this would be found here: http://wiki.processing.org/w/Advanced_OpenGL, and the fault lies somewhere in
PGraphicsOpenGL pgl = (PGraphicsOpenGL) g; // g may change GL gl = pgl.beginGL(); // always use the GL object returned by beginGL
I am just a happily hacking noob, tried to browse through the code and issue tracker, still no clues as to what/why/where.
I dearly hope this is not machine specific, but just in case, I am running win7 64, with an nvidia quadro inside.
Cheers,
D.
