category: Tcl sdesc: "Tk OpenGL rendering widget" ldesc: "Togl is a Tk widget for OpenGL rendering. Togl does almost no OpenGL drawing itself, instead it manages OpenGL drawing by calling various Tcl commands (a.k.a., callback functions). Those commands can be C functions that call OpenGL (in)directly or another Tcl package." homepage: http://togl.sourceforge.net/
