From windowing systems to virtual reality, real-time graphics code is ubiquitous. Programming
models for constructing graphics software, however, have largely escaped the attention of pro-
gramming languages researchers. This essay introduces the programming model of OpenGL, a
ubiquitous API for real-time graphics applications, for a language-oriented audience. It high-
lights six broad problems with the programming model and connects them to traditions in PL
research. The issues range from classic pitfalls, where established thinking can apply, to new
open problems, where novel research is needed.
