The document discusses drawing 3D scenes interactively. It covers viewing in OpenGL, including viewport transformation. It also discusses the OpenGL pipeline and different matrix representations for modeling transformations, projections, and converting between coordinate spaces, including the modelview, projection, and viewport matrices. It provides details on setting up and using these matrices to define the coordinate systems and drawing pipeline for 3D graphics.
