Creating a Debug Context

To get the most from OpenGL’s debugging facilities, it is necessary to create a debug context, which implies that you need control over the flags and parameters used to create the context. Context creation is a platform-specific task that is often handled by a wrapper layer such as GLUT. Modern implementations of GLUT (such as FreeGLUT, which we use in many of this book’s samples) include the function glutInitContextFlags(). This function takes a number of flags that can be used to control how contexts subsequently created behave. One of these flags is GLUT_DEBUG, which will enable a debug context. Many other platform abstraction layers have similar mechanisms. If you are not using an abstraction layer, then you will ...
