Buy the book if you want to know how NOT to design a C++ OpenGL classes for Windows. The book makes a big (and common) mistake of integrating OpenGL rendering context management into CView derived object, as if OpenGL could render to CView window only! You cant find very important Windows specific issues in the book, like rendering to DIB section and using it to integrate OpenGL rendering with Windows and GDI. Full screen rendering issues are also not covered. You also won't find any WindowsNT specific issues (like rendering to enhanced metafile).
